1、 In 2009, there were 9.8424 million hectares of natural grassland in Altay, Xinjiang, accounting for 83.4% of the total land area, of which 7.2393 million hectares were available, accounting for 14.5% of the total grassland area in Xinjiang. Seasonal grazing grassland is the main part of natural grassland. Rotation grazing of grassland according to season has always been the management mode of grassland animal husbandry in Altay region. The grassland in the whole region is basically rotated by summer pasture, spring and autumn pasture and winter pasture, and only Kanas small area is rotated by summer pasture and winter spring and autumn pasture

summer pasture: it is distributed in the cool climate of the mid alpine zone, mainly using subalpine meadow, alpine meadow and alpine grassland type grassland, and the utilization time is about 3 months

spring and autumn pasture: spring and autumn pasture is distributed in the mountains of the middle mountain zone, mainly using temperate meadow and temperate grassland in the mountains, and the utilization time in spring and autumn is about 3 months

winter pastures: most of them are distributed in the plain desert area with warm water shortage in low altitude basin, and a few are located in the leeward and sunny section of low mountain and inversion zone, and the utilization time is about 6 months

the grassland in Kanas small forest area was rotational grazing in summer and winter, spring and autumn. Winter, spring and autumn fields are distributed in the meadow belt of Zhongshan Mountain with mowing conditions. They can be used in winter, spring and autumn, and the utilization time is as long as 9 months. The area and carrying capacity of grazing grassland in different seasons in Altay area (table 6-15)

Table 6-15 area and carrying capacity of seasonal pastures in 2009 in Altay area source: data from animal husbandry department of Xinjiang Uygur Autonomous Region, 2009

the area of seasonal pastures among cities and counties in Altay area also varies greatly. The carrying capacity of spring and autumn pasture is 6.3 times that of summer pasture, and that of winter pasture is 10.6 times that of summer pasture. In summer, the grassland livestock of Jimunai county were scattered to the summer pasture of Altay City, burjin county and Habahe County, while in winter, the livestock of the above three counties were herded and overwintered in the winter pasture of Sawuer mountain in Jimunai county

In terms of animal husbandry, Altay is a large agricultural economic zone dominated by grassland animal husbandry, with 7.2393 million hectares of grassland available in four seasons, which is one of the main animal husbandry bases in Xinjiang. The livestock resources in Altay area include Kazakh native breed horse, white headed cattle, Xinjiang brown cattle, Simmental cattle, Chinese Holstein cattle, Kazakh horse, Xinjiang (Northern Xinjiang) Bactrian camel, Altay sheep, Xinjiang (Northern Xinjiang type) white cashmere goat, Xinjiang Qinggeli cashmere goat and Xinjiang West fine wool sheep. Altay fine wool sheep is the main livestock species in the livestock structure in this area, In 2008, there were 2.4984 million in stock, up 19.82% year on year

in 2005, the maximum number of livestock in Altay reached 5.2823 million, and in 2010 it was 4.3348 million, which was 1.9 and 1.6 times of 1978 respectively, showing a rapid growth trend, but also weakening the carrying capacity of the grassland in Altay (Fig. 6-2). In 2010, the output value of animal husbandry in Altay was 2.197 billion yuan

Fig. 6-2 the change of the maximum livestock raising amount in Altay from 1949 to 2010 is the development period of animal husbandry in Altay from 1949 to 1965. The maximum livestock raising amount increased from 432200 in 1949 to 3167900 in 1965. The characteristics of this period are that the maximum livestock proction continued to increase, and in 1955, it exceeded 1 million heads; In 1961, it exceeded 2 million and reached 2.257 million

From 1966 to 1986, it was the period of platform development. During this period, the maximum number of livestock raised increased and decreased, but remained between 2.27 and 2.47 million. In 1982, the highest number of livestock was 3.4732 million. During this period, the average was 2.88 million

There was a rising period from 1967 to 2005. The maximum number of livestock raised increased from 2.827 million in 1967 to 5.2823 million in 2005. Although it declined slightly in 1993 and 1994, it has been on the rise since then

From 2006 to now, it is a declining period. The characteristic of this period is that e to the limitation of the carrying capacity of the original grass and the adjustment of the structure of animal husbandry in the region, the maximum amount of animal husbandry has been decreasing. In 2006, the maximum number of livestock raised in Altay was 5.1971 million, which decreased to 4.3348 million in 2010. It can be predicted that the maximum livestock proction will decrease by 2020, and finally reach the average value of the platform development period from 1966 to 1986, which is about 3 million

Second, the characteristics of animal husbandry in Altay area

Altay area is a pure animal husbandry area, with vast grassland area, large usable area, excellent forage quality, large proportion of medium and high-grade forage species, less poisonous grass and non herbivorous grass, and more than 95% of all kinds of forage, with high utilization rate of forage

the grassland in the whole region was in a state of diversity, in which the area of plain desert grassland was the largest, accounting for 60.65% of the total available area, and the unit proctivity was the lowest, which was 1.76 HA / sheep; The minimum area of alpine steppe is 53 hectares; The highest proctivity of Lowland Meadow and plain swamp is 0.12 HA / sheep. According to the utilization pattern, there are four types (table 6-16). The winter pasture area is 3.4552 million hectares, the spring and autumn pasture area is 2.625 million hectares, the summer pasture area is 1.058 million hectares, and the spring, winter and autumn pasture area is 165900 hectares

Table 6-16 area and stocking capacity of four seasons pasture in 2008 in Altay area

data source: Animal Husbandry Bureau of Altay area, 2009

it can be seen from table 6-16 that winter pasture and spring and autumn pasture are 3.4 times and 2.56 times of summer pasture respectively according to available area, while theoretical stocking capacity is only 77.00% and 59.00% of summer pasture. In winter and spring and autumn, the number of pastures is very small, and the carrying capacity is also small. Summer pasture is the advantage and potential of this region, but it can only be used for 80 days in a year; Although the area of winter pasture is vast, it is short of water, the grass quality is poor, and the natural conditions are bad; Due to overgrazing and overgrazing, grassland degradation in spring and autumn pasture needs to be improved

from the grazing point of view, on the one hand, the four seasons pasture is very unbalanced, the winter pasture is 77.00% of the theoretical carrying capacity of the summer pasture, the spring and autumn pasture is 59.00% of the theoretical carrying capacity of the summer pasture, and the winter spring and autumn pasture is only 4.00% of the theoretical carrying capacity of the summer pasture. On the other hand, e to the sparse and low grass layer in winter pasture, livestock can not eat in every snowy year, "strong in summer, fat in autumn, thin in winter, dying in spring" and "yield rection in case of disaster" have become insurmountable barriers for nomadic proction

To sum up, the basic characteristics of animal husbandry in Altay area are grassland grazing, animal husbandry, grazing by water and grass, raising livestock by the sky, grazing and management of proction activities with seasons, which have strong regularity and dependence on nature. The balance degree of grassland in four seasons, the quality of grassland, the amount of grass stored and the climate directly affect the development of animal husbandry

(1) grassland degradation is serious and overload is excessive.

e to the change of climate conditions, the impact of human proction activities, the increase of livestock carrying capacity per unit area and the lack of scientific grazing management, the ecological balance of grassland has been seriously damaged and the contradiction between grassland and livestock is sharp (table 6-17)

In addition, according to a special report entitled "fission of Altay Grassland" in Altay daily on November 12, 2009, the theoretical carrying capacity of natural grassland is 9.54 million sheep units. At the end of 2009, the actual carrying capacity of Altay area was 16.88 million sheep units, and 7.34 million sheep units were overloaded, with an average overload rate of 75%. The available area of summer pasture is 15.24 million mu, which can carry 4.73 million sheep units. The existing livestock is 6.59 million sheep units, and the overload rate is 39.00%; The spring and autumn pasture has a usable area of 39.04 million mu and can carry 2.49 million sheep units. At present, there are 6.17 million sheep units and 3.68 million sheep units overloaded, with an overload rate of 148%; The available area of winter pasture is 51.83 million mu, which can carry 2.31 million sheep units. The existing livestock is 4.12 million sheep units, and the overload rate is 71%. 79.34 million mu grassland has been degraded to varying degrees, with the degradation rate of 73%. The degradation rates of summer pasture, spring and autumn pasture and winter pasture are 58%, 89% and 72% respectively, of which 44.3 million mu are seriously degraded, accounting for 40%

note: summer pasture and spring and autumn pasture are calculated by the highest feeding amount, and winter pasture is calculated by the number of stocks at the end of the year

data source: Bureau of animal husbandry of Altay region, concted a comprehensive grassland resource survey in 2009

2007, and the number of main 9 grassland categories did not decrease, However, the biomass, height and proportion of excellent forage decreased significantly, especially in mountain meadow, meadow steppe, mountain steppe and grassland desertification (table 6-18, table 6-19, table 6-20). The grassland area in mountainous area is about 25% of the total grassland area in the whole region, but the actual carrying capacity of grassland is as high as 57.00%

Table 6-20 main grassland types in 1982 and 2007. According to incomplete statistics, ring the 20 years from 1969 to 1989, the valley forests of the ulungu River and the Erqis River Basin decreased by 487000 mu, and still decreased at the rate of 10000-20000 mu per year in 2009. At the same time, in order to expand the area of cultivated land, farmers and herdsmen cut down the trees around the farmland. In addition, livestock gnaw on branches, bark and tree seedlings, resulting in the continuous decline of the natural regeneration ability of the forest and the decreasing of the forest area. Affected by the abnormal climate, the snow line rises, the glacier melts, the groundwater level drops, the secondary forest in the valley dies in large area, the area of wetland in the region declines sharply, the function of forest water conservation declines, the precipitation in the whole region decreases significantly, the grassland fire and forest fire happen year after year, and the biodiversity is seriously damaged

In Altay area, there are many natural disasters in the proction of animal husbandry. The proction of animal husbandry is still extensive and depends on the weather to raise livestock. The situation of livestock "full in summer, fat in autumn, thin in winter and starved to death in spring" has been in a vicious circle. The shortage of forage in winter and spring has resulted in the low disaster resistance ability of animal husbandry proction, especially in the case of natural disasters such as gale, snow disaster and drought, resulting in the shortage of forage storage, resulting in a passive situation of big disaster and small disaster

(3) it is easy to be damaged by insects and rats, and it is very serious. The area of locust and rodent infestation is over 133300 hectares every year, accounting for more than 15% of the total grassland area. Among them, the area of locusts is more than 53300 hectares. In some areas with dense rodent holes, the holes are connected, and the ground is mined out, and the grass and shrub plants on the ground are withered

In 2009, the total area of grassland with water shortage and serious water shortage was 6.0388 million hectares

Polkadot is a blockchain agreement, It aims to support multiple chains within a blockchain network. It aims to overcome a problem in the current blockchain environment: hundreds of blockchains exist in isolation and have little communication ability

History of Polkadot
Polkadot was developed by parity technologies and led by Gavin wood and Jutta Steiner, two former Ethereum executives. The project is also supported by the Web3 foundation, a closely related organization that provides funding, advocacy, research and cooperation for the project

parity was established in 2015. Initially, it began to develop node software only for Ethereum, known as the parity Ethereum client. The company has phased out its support for the project, allowing it to focus on Polkadot and its related project, substance

development started in November 2017, when developers released the first piece of code on GitHub

the company launched two proof of concept in mid-2018 and deployed Polkadot's first parallel chain in July 2018. Polkadot will be launched as "initial" in May 2020, and token transfer will be launched in August 2020

as of September 2020, Polkadot's relay chain has not been activated, and the on chain auction has not been launched
