1. 1. Natural resources: the Pearl River Delta is a tropical Delta, because its geographical location is in the south of Tropic of cancer (small delta), in the large delta, also in the north latitude 23 ° 40′—21 ° Most of them are tropical. In terms of climate, the delta is also a tropical region (see phenology, 1962, by Zhu Kezhen et al.). The vegetation landscape is also affected by it, and it develops into tropical monsoon forest vegetation. In addition, the northern part of the delta is the mountainous area of northern Guangdong, which acts as a barrier to the cold current from the north, so that the tropical vegetation can invade the mountain area north of the Tropic of cancer along the valley. The tropical characteristics of the Pearl River Delta are reflected in the large amount of water, small sediment content, many branching and radiating channels, and the development of wide and deep channels. The delta is flat with less rainfall than the surrounding hills, with an average of about 1600 mm, while the rainfall in the surrounding areas can reach 2000-2600 mm. Rainfall is concentrated in summer and less in winter. This rainy and dry season is the tropical climate characteristic. It is different from the high temperature and rainy years in the equatorial zone. Therefore, equatorial crops such as rubber tree, coconut, betel nut, cocoa, pepper and rian can not be introced in the Pearl River Delta, but tropical crops such as sisal, mango, pineapple and citronella can only be introced< Tourism resources: Yuanming new garden is located at the foot of Shilin mountain, Jiuzhou Avenue, Zhuhai, covering an area of about 1.39 square kilometers. It is built with Beijing Yuanming garden as the original manuscript and selected 18 of the 40 scenes of Yuanming garden according to the ratio of 1:1.

on the Bank of the beautiful Xianglu Bay in Zhuhai City, there stands a huge stone carving, the Zhuhai fisherman's daughter. She is wearing a Xiang Zhu, carrying a fishing net, holding her trousers lightly, holding a crystal clear pearl in her hands. With a look of joy and shame, she shows light to the world and offers treasures to mankind. Standing 8.7 meters and weighing 10 tons, this stone carving is composed of 70 pieces of granite. It is a masterpiece of Pan he, a famous Chinese sculptor.

There are more than 30 shopping malls in the city, with goods ranging from high-end household appliances, jewelry and jade, ancient books and paintings to food, clothing, stationery, medicine and daily necessities< Instrial characteristics: the overall level of export-oriented economy is high. The Pearl River Delta region gives full play to its geographical advantages adjacent to Hong Kong and Macao and the favorable conditions for overseas Chinese to spread all over the world. Guided by the international market and relying on the domestic market, it promotes the high-level and rapid development of the export-oriented economy. In 1994, the total export trade of the Pearl River Delta region reached 38.46 billion US dollars, accounting for 76.6% of the total export trade of the whole province in that year; The actual utilization of foreign capital reached 8.798 billion US dollars, accounting for 68% and 24% of the total amount of foreign capital actually utilized in the whole province and the whole country respectively
the optimization of instrial structure is reasonable. The Pearl River Delta region has completed the transformation from the traditional agricultural economy to an important manufacturing center, and has successfully realized the comprehensive linkage development of economy and society led by the secondary and tertiary instries. The proportion of primary, secondary and tertiary instries in GDP in the Pearl River Delta region has grown from 25.8:45.5:28.9 in 1980 to 8.8:51.2:40 in 1994. On the whole, the instrial structure of the Pearl River Delta has basically changed from traditional agriculture to instrialization, and then to instrial diversification
the pattern of agricultural instrialization has basically taken shape. Since the reform and opening up, with the acceleration of the process of rural urbanization, the market-oriented, socialized and intensive proction and management pattern of agriculture in this area has formed rapidly. In the proction and operation activities, the agricultural instrialization development mode of specialized proction, socialized service and enterprise management has been formed, which is guided by domestic and foreign markets, centered on economic benefits, based on resource development, supported by planting and breeding instry, integrated with agricultural instry, technology and trade, and integrated with proction, processing and marketing

I'm so tired. If you don't add points, you're really sorry for me

2. The Pearl River Delta, or PRD for short, is a delta formed by the impact and sedimentation of the Xijiang, Beijiang and Dongjiang rivers of the Pearl River when they enter the sea, covering an area of more than 10000

3. At present, there are six special economic zones in China; Shenzhen and Zhuhai, Kashgar and Zhuhai. In 1988, Hainan Island was regarded as a special economic zone, including Shantou, Zhuhai, Shenzhen and Shantou
in 1980, four special economic zones (SEZs) and Xiamen were established: Shenzhen, Hainan Island and Xiamen< There are two special economic zones in the Pearl River Delta

4. City and river are a pair of dialectical relations. River breeds city and city influences river
nature breeds rivers, which in turn nurture cities. Since ancient times, the rise and prosperity of the city are closely related to the reproction of rivers. Many times, the river is the pronoun of a city, the soul of a city and the mother of a city
the development of cities also has a great influence on rivers. For thousands of years, although history has changed and people have changed, cities and rivers can generally live in harmony and respect each other. But in the era of instrialization, cities and rivers seem to become enemies overnight. Sewage discharge, crazy sand mining, tree cutting and deforestation, the mother river that has been nurturing itself, the city "requites virtue with resentment". The river is not willing to be humiliated. The mud and sand, the turbid river and the flooded city make the city restless.

5. 1、 The characteristics of economic and social development in the Pearl River Delta region
1. From 1980 to 1996, the average annual growth rate of GDP in the Pearl River Delta region was 17.8%, which was not only higher than the average growth rate of 14.5% in the whole province and 9.7% in the whole country ring the same period, but also higher than the average growth rate of the "four little Dragons" in Asia ring the economic take-off period< The overall level of export-oriented economy is high. The Pearl River Delta region gives full play to its geographical advantages adjacent to Hong Kong and Macao and the favorable conditions for overseas Chinese to spread all over the world. Guided by the international market and relying on the domestic market, it promotes the high-level and rapid development of the export-oriented economy. In 1994, the total export trade of the Pearl River Delta region reached 38.46 billion US dollars, accounting for 76.6% of the total export trade of the whole province in that year; The actual utilization of foreign capital reached 8.798 billion US dollars, accounting for 68% and 24% of the total amount of foreign capital actually utilized in the whole province and the whole country respectively
3. The optimization of instrial structure is reasonable. The Pearl River Delta region has completed the transformation from the traditional agricultural economy to an important manufacturing center, and has successfully realized the comprehensive linkage development of economy and society led by the secondary and tertiary instries. The proportion of primary, secondary and tertiary instries in GDP in the Pearl River Delta region has grown from 25.8:45.5:28.9 in 1980 to 8.8:51.2:40 in 1994. On the whole, the instrial structure of the Pearl River Delta has basically changed from traditional agriculture to instrialization, and then to instrial diversification
4. The pattern of agricultural instrialization has been basically formed. Since the reform and opening up, with the acceleration of the process of rural urbanization, the market-oriented, socialized and intensive proction and management pattern of agriculture in this area has formed rapidly. In the proction and operation activities, the agricultural instrialization development mode of specialized proction, socialized service and enterprise management has been formed, which is guided by domestic and foreign markets, centered on economic benefits, based on resource development, supported by planting and breeding instry, integrated with agricultural instry, technology and trade, and integrated with proction, processing and marketing
5. Coordinated and balanced development of urban and rural areas. Since the reform and opening up, with the development of rural instrialization, the Pearl River Delta has accelerated urbanization. At the end of the 1970s, there were only dozens of towns. In the mid-1980s, there were 200, 406 in 1992 and 597 in 1994. It has increased nearly 10 times in 15 years. Zhongshan and Dongguan have jurisdiction over only established towns, but not counties and townships. In 1994, the proportion of non-agricultural population in the Pearl River Delta was 45.2%, 16 percentage points higher than that of the whole province. Now, every 65-127; There is a town in an area of one square kilometer. In the process of urbanization, the Pearl River Delta region complements and combines the advantages of service function of modern towns with the advantages of idyllic customs of modern villages, promotes the coordinated and balanced development of urban and rural areas, and forms a distinctive fusion area
6. Social mobility tends to be healthy and orderly. The Pearl River Delta is the largest gathering place of migrant workers in China. At present, there are millions of migrant workers in the region, forming a large-scale and characteristic migrant workers flow group. This kind of social mobility conforms to the logic of modern market economy and is the natural embodiment of the optimal allocation of human resources. After years of exploration and efforts, the management of migrant workers by relevant government departments and labor agencies has basically realized the management according to law, which has made the social mobility from disorder to order.

6. The Pearl River Delta region includes Guangzhou, Shenzhen, Zhuhai, Foshan, Jiangmen, Zhongshan, Dongguan, Huicheng District, Huiyang, Huidong and BOLUO of Huizhou City, and Ruizhou District, Dinghu District, Gaoyao district and Sihui District of Zhaoqing City. The area of the whole region accounts for 23.4% of the total area of the whole province, and the population accounts for 31.4% of the total population of the whole province (1994). In recent years, the GDP accounts for about 70% of the GDP of the whole province. The Pearl River Delta is one of the fastest growing regions in China. With the rapid development of economy, the social development of the region presents the characteristics of high degree of rural instrialization and rapid process of urban-rural integration. The Youth League organizations at all levels in the Pearl River Delta region have actively explored and practiced how to promote the development of the work of the Communist Youth League against the background of the local economic and social development and according to the actual situation of the local youth. The research group of the general office of the people's Republic of China went to Guangdong to conct a survey of the region. During the survey, it was found that the exploration made by the Youth League organizations in the Pearl River Delta region in recent years to adapt to the development of market economy can be summed up as: Socialized Operation and career development. 1、 The characteristics of economic and social development in the Pearl River Delta region 1. Sustained and rapid economic growth. From 1980 to 1996, the average annual growth rate of GDP in the Pearl River Delta region was 17.8%, which was not only higher than the average growth rate of 14.5% in the whole province and 9.7% in the whole country ring the same period, but also higher than the average growth rate of the "four little Dragons" in Asia ring the economic take-off period. 2. The overall level of export-oriented economy is high. The Pearl River Delta region gives full play to its geographical advantages adjacent to Hong Kong and Macao and the favorable conditions for overseas Chinese to spread all over the world. Guided by the international market and relying on the domestic market, it promotes the high-level and rapid development of the export-oriented economy. In 1994, the total export trade of the Pearl River Delta region reached 38.46 billion US dollars, accounting for 76.6% of the total export trade of the whole province in that year; The actual utilization of foreign capital reached 8.798 billion US dollars, accounting for 68% and 24% of the total amount of foreign capital actually utilized in the whole province and the whole country respectively. 3. The optimization of instrial structure is reasonable. The Pearl River Delta region has completed the transformation from the traditional agricultural economy to an important manufacturing center, and has successfully realized the comprehensive linkage development of economy and society led by the secondary and tertiary instries. The proportion of primary, secondary and tertiary instries in GDP in the Pearl River Delta region has grown from 25.8:45.5:28.9 in 1980 to 8.8:51.2:40 in 1994. On the whole, the instrial structure of the Pearl River Delta has basically changed from traditional agriculture to instrialization, and then to instrial diversification. 4. The pattern of agricultural instrialization has been basically formed. Since the reform and opening up, with the acceleration of the process of rural urbanization, the market-oriented, socialized and intensive proction and management pattern of agriculture in this area has formed rapidly. In the proction and operation activities, the agricultural instrialization development mode of specialized proction, socialized service and enterprise management has been formed, which is guided by domestic and foreign markets, centered on economic benefits, based on resource development, supported by planting and breeding instry, integrated with agricultural instry, technology and trade, and integrated with proction, processing and marketing. 5. Coordinated and balanced development of urban and rural areas. Since the reform and opening up, with the development of rural instrialization, the Pearl River Delta has accelerated urbanization. At the end of the 1970s, there were only dozens of towns. In the mid-1980s, there were 200, 406 in 1992 and 597 in 1994. It has increased nearly 10 times in 15 years. Zhongshan and Dongguan have jurisdiction over only established towns, but not counties and townships. In 1994, the proportion of non-agricultural population in the Pearl River Delta was 45.2%, 16 percentage points higher than that of the whole province. Now, every 65-127; There is a town in an area of one square kilometer. In the process of urbanization, the Pearl River Delta region complements and combines the advantages of service function of modern towns with the advantages of idyllic customs of modern villages, promotes the coordinated and balanced development of urban and rural areas, and forms a distinctive fusion area. 6. Social mobility is in a healthy and orderly way. The Pearl River Delta is the largest gathering place of migrant workers in China. At present, there are millions of migrant workers in the region, forming a large-scale and characteristic migrant workers flow group. This kind of social mobility conforms to the logic of modern market economy and is the natural embodiment of the optimal allocation of human resources. After years of exploration and efforts, the management of migrant workers by relevant government departments and labor agencies has basically realized the management according to law, which has made the social mobility from disorder to order. 2、 The characteristics of youth groups in the Pearl River Delta region 1. The composition of youth groups is binary structure. The youth groups in the Pearl River Delta are composed of local youth and migrant youth. According to statistics at the end of 1997, the total number of young people in Guangdong Province was 15.89 million, and there were more than 5 million young migrant workers in Guangdong Province. Young migrant workers are mainly concentrated in the Pearl River Delta. In some towns in the Pearl River Delta, the number of young migrant workers is basically equal to that of local youth. In some towns or administrative villages, the number of young migrant workers has exceeded that of local youth by several times, even more than ten or dozens of times. For example, there are more than 6000 young migrant workers in Dongshan District of Guangzhou, accounting for 65% of the total number of youth employment in the district. Another example is that there are more than 900000 young migrant workers in Bao'an District of Shenzhen, which is more than four times of the local permanent population; There are more than 15000 young migrant workers in Huanggang village, Futian District, which is 40 times of that in the village; There are nearly 30000 young migrant workers in Ailian village of Longgang District, while there are only 2907 villagers in this village. 2. The differentiation of youth group is obvious. In general, the youth in the Pearl River Delta are divided into two basic groups: local youth and migrant youth. With the further development of market economy and the increasingly extensive social contact, the integration and differentiation of youth groups in the Pearl River Delta are also deepening. Among them, "three high" youth and "four no" youth are two noticeable groups“ "Three high" youth refers to the youth with high ecation background, high position and high income. These young people are the "elites" among the youth, and their behavior style has obvious guiding and exemplary role in the youth“ The "four no" youth is a special youth group in the process of rural urbanization. These young people do not study, study, do not do business, do not work, mainly live by renting their own property, with obvious parasitism. According to the investigation and analysis of local youth league organizations, from the perspective of occupational classification, young workers mainly pursue stable income, young staff generally yearn for a decent and glorious life, civil servants prefer a smooth future, and intellectuals focus on seeking development opportunities. Among them, with the emergence and rapid development of various financial institutions, management institutions and new companies in the process of reform and opening up, the group of young staff has grown rapidly. Their knowledge level, social status and economic income are relatively high, and their life style and behavior style are obviously different from those of other professional groups. In short, there are obvious differences in the interest requirements and spiritual pursuit of different professional youth groups. Moreover, the diversification of this demand leads to the differentiation of youth groups. In the Pearl River Delta region, young people spontaneously set up professional associations based on common hobbies and interests, and their activities show obvious group characteristics. 3. Youth play an important role in the economic field. In the Pearl River Delta region, youth is the main creative force of material wealth. In the new economic organization, which is the leading force to promote local economic development, young people are basically working. For example, the large-scale young migrant workers who mainly work in the new economic organizations are and will play an irreplaceable role in the local economic development. As a new economic growth point in high-tech enterprises, young people are the vanguard of scientific and technological innovation. Zhongshan City can be selected as one of the 30 advanced cities of "prospering the city through science and technology" in China, which is inseparable from its strong young scientific research team. According to statistical analysis, in 1995, the contribution rate of science and technology to economic growth in Zhongshan City was 45%, more than ten percentage points higher than the national average. 4. Career choice focuses on development. When young people in the Pearl River Delta choose their careers, they usually pay more attention to whether they can bring development opportunities. According to the survey of local youth league organizations, 50.4% and 37.3% of young people in Zhuhai and Panyu respectively consider their long-term development prospects and personal interests and specialties first when choosing their careers. In the Pearl River Delta, a region with relatively mature economic development, the society can provide alternative employment opportunities for young people at all levels, thus realizing the unity of labor as a means of livelihood and realizing their own value to a greater extent. 5. Pay attention to social life. In the survey, I feel that the youth in the Pearl River Delta regard the social life beyond the "eight hours" as a very important part of their whole life, and regard the society as an important stage for their own activities. Moreover, the field of youth's social life is very extensive, and the social behavior across units, groups and regions is a very common phenomenon in youth's social life. The places of youth's social life are mainly public places. The traditional way of visiting relatives and friends and chatting is considered a waste of time. In daily interpersonal communication, young people attach great importance to independence, equality and mutual respect. In this area, youth culture is no longer a subculture, but a mainstream culture, leading the trend of cultural development to a large extent.

The Pearl River Delta is located in the south central part of Guangdong Province, the estuary of the Pearl River and the south of the Han nationality. The Pearl River Delta is not only a geographical region, but also an economic region, but its scope is slightly different. In a narrow sense, the Pearl River Delta economic zone includes Guangzhou, Shenzhen, Foshan, Dongguan, Huizhou, Zhongshan, Zhuhai, Jiangmen and Zhaoqing. The newly planned expansion of Shanwei (Shenzhen Shantou Special Cooperation Zone), Qingyuan, Yunfu, Heyuan and Shaoguan is the Pearl River Delta urban agglomeration formed by 14 cities. The Greater Pearl River Delta also includes Hong Kong and Macao special administrative regions

extended data

the Pearl River Delta is located in the southeast of Guangdong Province, the lower reaches of the Pearl River, adjacent to Hong Kong and Macao, across the sea from Southeast Asia, with convenient sea and land transportation, known as China's "South Gate"

The Pearl River Delta has become a world-famous manufacturing and export base, and one of the preferred regions for instrial transfer in the world. It has initially formed a group of enterprises and instries focusing on electronic information and home appliances

The Pearl River Delta is the main R & D base of high-tech instry in Guangdong Province, the largest high-tech instrial belt in China, and an important proction base of high-tech instry at home and abroad

the comprehensive information index of the Pearl River Delta economic zone was 67.6%, 3.3 percentage points higher than that of the whole province. The Pearl River Delta region and Shenzhen City were identified as the first batch of national electronic information instry bases; The first Linux public technical support service center in China has been built and put into use

"Greater Pearl River Delta" refers to the area composed of nine cities in the former Pearl River Delta, Hong Kong Special Administrative Region and Macao Special Administrative Region, which is the busiest and most developed area in the whole province in terms of transportation. It has initially formed a system with Guangzhou as the center, combining various modes of transportation such as railway, highway, waterway and civil aviation to connect Hong Kong, Macao and Macao Communication of the province and the country's more developed comprehensive transportation network

At the end of 2008, the State Council issued the outline of the reform and development plan for the Pearl River Delta region, covering nine cities, namely Guangzhou, Shenzhen, Foshan, Dongguan, Zhongshan, Zhuhai, Jiangmen, Zhaoqing and Huizhou“ "Greater Pearl River Delta" refers to the original nine cities in the Pearl River Delta, together with the Hong Kong Special Administrative Region and the Macao Special Administrative Region. It is the leading region of China's reform and opening up, and one of the important economic centers in China.

has a prominent leading role and strategic position in the national economic and social development and the overall situation of reform and opening up. Integration has become a national strategy. Around the integration of infrastructure, instrial layout, urban and rural planning, public services and environmental protection, the economic and geographical structure of the Pearl River Delta is undergoing major changes. The "double track" construction of track and greenway provides basic conditions for the acceleration of regional integration in the Pearl River Delta. The 11 city economic circles have formed quietly, and the inner cities of the Pearl River Delta are moving towards organic integration

8. At present, about half of the gross national proct of the Pearl River Delta region is achieved through international trade, and the total foreign trade exports account for more than 10% of the whole country. Most of the procts of many enterprises are supplied to the international market. The basic way to develop the export-oriented economy in the Pearl River Delta is to introce foreign capital, advanced technology, equipment and management. At the same time, the region has the advantages of being close to Hong Kong and Macao, the hometown of overseas Chinese, the excellent seaport and the rich labor force. In addition, the preferential policies formulated by the state make it a geomantic treasure land to attract foreign investment and foreign enterprises to settle down< First, the characteristics of economic and social development in the Pearl River Delta region. From 1980 to 1996, the average annual growth rate of GDP in the Pearl River Delta region was 17.8%, which was not only higher than the average growth rate of 14.5% in the whole province and 9.7% in the whole country ring the same period, but also higher than the average growth rate of the "four little Dragons" in Asia ring the economic take-off period< 2.

The optimization of instrial structure is reasonable. The Pearl River Delta region has completed the transformation from the traditional agricultural economy to an important manufacturing center, and has successfully realized the comprehensive linkage development of economy and society led by the secondary and tertiary instries. The proportion of primary, secondary and tertiary instries in GDP in the Pearl River Delta region has grown from 25.8:45.5:28.9 in 1980 to 8.8:51.2:40 in 1994. On the whole, the instrial structure of the Pearl River Delta has basically changed from traditional agriculture to instrialization, and then to instrial diversification< 4. The pattern of agricultural instrialization has been basically formed. Since the reform and opening up, with the acceleration of the process of rural urbanization, the market-oriented, socialized and intensive proction and management pattern of agriculture in this area has formed rapidly. In the proction and operation activities, the agricultural instrialization development mode of specialized proction, socialized service and enterprise management has been formed, which is guided by domestic and foreign markets, centered on economic benefits, based on resource development, supported by planting and breeding instry, integrated with agricultural instry, technology and trade, and integrated with proction, processing and marketing< 5.

In the Pearl River Delta region, young people spontaneously set up professional associations based on common hobbies and interests, and their activities show obvious group characteristics< Youth plays an important role in the economic field. In the Pearl River Delta region, youth is the main creative force of material wealth. In the new economic organization, which is the leading force to promote local economic development, young people are basically working. For example, the large-scale young migrant workers who mainly work in the new economic organizations are and will play an irreplaceable role in the local economic development. As a new economic growth point in high-tech enterprises, young people are the vanguard of scientific and technological innovation. Zhongshan City can be selected as one of the 30 advanced cities of "prospering the city through science and technology" in China, which is inseparable from its strong young scientific research team. According to statistical analysis, in 1995, the contribution rate of science and technology to economic growth in Zhongshan City was 45%, more than ten percentage points higher than the national average< 4. Career choice focuses on development. When young people in the Pearl River Delta choose their careers, they usually pay more attention to whether they can bring development opportunities. According to the survey of local youth league organizations, 50.4% and 37.3% of young people in Zhuhai and Panyu respectively consider their long-term development prospects and personal interests and specialties first when choosing their careers. In the Pearl River Delta, a region with relatively mature economic development, the society can provide alternative employment opportunities for young people at all levels, thus realizing the unity of labor as a means of livelihood and realizing their own value to a greater extent

5. Pay attention to social life. In the survey, I feel that the youth in the Pearl River Delta regard the social life beyond the "eight hours" as a very important part of their whole life, and regard the society as an important stage for their own activities. Moreover, the field of youth's social life is very extensive, and the social behavior across units, groups and regions is a very common phenomenon in youth's social life. The places of youth's social life are mainly public places. The traditional way of visiting relatives and friends and chatting is considered a waste of time. In daily interpersonal communication, young people attach great importance to independence, equality and mutual respect. In this area, youth culture is no longer a subculture, but a mainstream culture, leading the trend of cultural development to a large extent< In the Pearl River Delta, the concept of "socialization" used by Youth League organizations in different cities has different meanings. From the perspective of operation mode, the socialization of the work of the Communist Youth League in the Pearl River Delta is mainly reflected in three aspects

1. Social oriented design activities. The activities designed by the Pearl River Delta Youth League have a distinctive feature, that is, they are oriented to the youth and the masses of the whole society, so that people can participate voluntarily outside the "eight hours", so that the activities have a wide range of social participation. League organizations are generally only responsible for the design and publicity of activities, and rarely organize directly. For example, the "youth culture square" launched by the Guangdong Provincial Youth League Committee and the "everyone's music" stage founded by the Shenzhen Municipal Youth League Committee are all like this. Every weekend, the "youth culture market" activity is held in Tianhe City Square, a famous commercial network in Guangzhou. The stage is open-air, with free access and visitors. Now, youth culture square activities have been launched in cities in the Pearl River Delta. In Shenzhen, with youth as the main body and the principle of "voluntary, self recommendation, self acting and co entertainment", the "everyone's music" stage has held more than 2000 performances since its first opening in July 1986, with more than 40000 performers and more than 4.5 million audiences. There are more than 100 "everybody's music" stages of different scales in the city. "Everyone's music" is well-known in all walks of life. It is known as "night club for civilians in the special economic zone" and "blue sky in the hearts of migrant workers". During the period of welcoming Hong Kong's return to the motherland, the activities of "building a memorial forest for Hong Kong's return" and "the relay race of the footprints of Hong Kong's return" designed by the Shenzhen Municipal Youth League Committee were also carried out for the society

2. The organization construction of the Communist Youth League is the difficulty in the development of the Communist Youth League under the market economy. In this regard, the Pearl River Delta Youth League has taken new steps in its exploration. Their main methods are: to break the restriction of administrative subordination and the pattern of "one factory and one branch", and to explore new ways for state-owned enterprises to build Youth League by setting up enterprise youth working committee, building Youth League with interest, building Youth League in employee dormitory area, and building Youth League in activity center. By relying on the flexible forms of trade union, community and instry, the new economic organizations can build the league

The Pearl River Delta is not only a geographical region, but also an economic region. Located in the central part of Guangdong Province. The new Pearl River Delta Urban Agglomerations include Guangzhou, Foshan, Zhaoqing, Qingyuan, Yunfu, Shaoguan, Shenzhen, Dongguan, Huizhou, Shanwei, Heyuan, Zhuhai, Zhongshan, Jiangmen and Yangjiang, which are formed by 9 + 6 cities

The Pearl River Delta is the largest plain area in Guangdong Province. Advanced manufacturing and modern service bases with global influence, the main regions of China's participation in economic globalization, the national science and technology innovation and R & D bases, the important engine of national economic development, the gateway of South China's opening to the outside world, and the leader of radiating and driving the development of South China, central China and southwest China

the Pearl River Delta is one of the three urban agglomerations with the largest population, the strongest innovation ability and the strongest comprehensive strength in China

extended data:

location of Pearl River Delta ° 40'－ twenty-one ° 30' Most of them are tropical. In terms of climate, the great delta belongs to the south subtropical region (see phenology, 1962, by Zhu Kezhen et al.)

The Luoping mountain range is the boundary between the West and the north, that is, to the west of the Luoping mountain range is Xijiang valley area, which is traditionally called the mountainous area of western Guangdong; To the north of the mountains is the Beijiang River system, or the mountainous area of northern Guangdong. The Luofu Mountain Area on the east side is the eastern boundary of the delta

The landform age of the hilly platform is older than that of the plain; Therefore, most of the weathering crust has developed into lateritic red soil, which belongs to latosol red soil. Only higher hills can see the development of red soil, which is concive to the growth of subtropical evergreen broad-leaved forest

The Pearl River Delta, formerly known as the Yuejiang plain, is the general name of the large delta formed by the common alluvial of the Xijiang River and the Beijiang River and the small delta formed by the alluvial of the Dongjiang River. It is an inverted triangle. The bottom is a line from Sanshui City in the West and Guangzhou City in the east to Shilong, and the top is yamen Bay. It covers an area of 11000 square kilometers

The alluvium is thin, generally 20-30m. The ground fluctuates greatly, surrounded by hills, mountains and islands, accounting for 30% of the area. The central part is plain, distributed in the south of Guangzhou, north of Zhongshan, east of Jiangmen and west of Humen. The average annual sediment discharge of the Pearl River system is more than 80 million tons, and the Delta near the estuary is still extending to the South China Sea. In the estuary area, it can stretch 10-120 meters per year on average, becoming one of the key reclamation areas in China

climate condition

belongs to subtropical climate, warm and humid all year round. The annual average temperature is 21-23 ℃, the coldest is 13-15 ℃ in January, and the hottest is more than 28 ℃ in July. From June to October, there are often typhoons, with concentrated rainfall and the hottest weather. The average annual precipitation is more than 1500 mm

the rainy season is synchronous with the high temperature season, the soil is fertile, and the river is vertical and horizontal, which is beneficial to agriculture. The altitude is below 200 meters and the terrain is flat; The climate is high temperature and rainy, dominated by south subtropical monsoon

The climate in the Pearl River Delta is characterized by four unknown seasons, no snow in three winters, evergreen trees, evergreen fields and no frost. According to Zhu Kezhen in his book "special climatology", the tropics is a place where "all seasons are summer, and every rain becomes autumn". He thinks that the south of Wuling is the tropics. But the Pearl River Delta is within the subtropical zone
