| "Beautiful China Construction"is a major construction strategic idea and task proposed in the report of the"18th National Congress"of the party,and is the core goal of promoting the country to achieve high-quality development.In view of the important role of animal husbandry in the economic and social development of pastoral areas,the status of animal husbandry development determines to a large extent the degree of"beautiful China"in the future.This article starts from economic,environmental and social dimensions,based on land cover use classification data,grassland ecosystem net primary productivity,and statistical yearbook data from three aspects:the spatial distribution of pastoral production,the capacity of grassland resources,and the sustainability of herders livelihoods.Diagnose the target,build a comprehensive evaluation system for the construction of beautiful pastoral areas,and quantitatively evaluate the construction level of beautiful pastoral areas in the leagues and cities of the Inner Mongolia Autonomous Region from 2001 to 2019.It is expected to provide a scientific basis for the construction of beautiful pastoral areas in the Inner Mongolia Autonomous Region.The main conclusions are as follows:(1)The rationality of the allocation of animal husbandry production space:The average value of the rationality index for the allocation of animal husbandry production space in Inner Mongolia from 2001 to 2019 was 30.37%,which increased from 35.72%in 2001 to 44.88%in 2019,an increase of 25.63%.The average value of the rationality index for the allocation of animal husbandry production space in the leagues and cities was between 1.92%and 97.62%.The animal husbandry production space allocation of the Xilin Gol League was the most reasonable,and the Alxa League was the lowest,only 1.97%.The average NPP of grassland in all league cities was between 25.22 and 308.46 g C/m~2.The highest NPP in Xing’an League was 308.46 g C/m~2,and the lowest in Alxa League,accounting for only 8.18%of the NPP in Xing’an League.From 2001 to 2019,the average feeding volume at the end of June in Inner Mongolia was 151,790,706 sheep units,and the average feeding volume at the end of December was 97479704 sheep units.The feeding volume at the end of June increased by124.09%in the past 20 years,with an annual growth rate of 6.53%;at the end of December Feeding volume has increased by 71.67%.(2)Resource guarantee capacity:The average supply and demand balance index of grassland resources in the Inner Mongolia Autonomous Region from 2001 to 2019 was28.63%,showing an overall downward trend,from 37.00%in 2001 to 21.90%in 2019,a decrease of 40.81%.The reduction rate was 2.15%.In 2002,the supply and demand balance index of grassland resources in the Inner Mongolia Autonomous Region was the largest at42.75%,and in 2016,the supply and demand balance index was the lowest at 18.95%.The average value of the supply-demand balance index of grassland resources in the leagues and cities was between 11.13%and 59.49%.The grassland resource supply-demand balance index of the Xilin Gol League was the largest,and the Alxa League was the lowest,which was only18.71%of the Xilin Gol League.In 19 years,the average SNPP of grassland resources ecological supply in Inner Mongolia was 8.62 Tg C,which increased from 7.14 Tg C in 2001to 8.55 Tg C in 2019,an increase of 19.75%.The average SNPP value of each league city was between 0.01 and 2.38 Tg C.The ecological supply of grassland resources in Xilin Gol League was the largest,and Wuhai City was the lowest,only 0.26%of Xiling Gol League.From 2001to 2019,the average CNPP demand for grassland resources produced by the livestock industry in Inner Mongolia was 31.23 Tg C.The CNPP increased from 19.3 Tg C in 2001 to 39.04 Tg C in 2019,an increase of 102.31%and an annual growth rate of 5.38%.From 2001 to 2019,the average value of CNPP in Inner Mongolia’s leagues and cities was between 0.03 and 5.36Tg C.The demand for grassland resources for animal husbandry production in Chifeng City was the largest,and that in Wuhai City was the lowest,only 0.53%of that in Chifeng City.(3)Livelihood sustainability of animal husbandry:The average value of Inner Mongolia’s Livelihood Sustainability Index from 2001 to 2019 was 21.66,which increased from 21.32 in 2001 to 24.81 in 2019,an increase of 16.38%,showing an overall upward trend.In 2017,the highest livelihood sustainability index of Inner Mongolia Autonomous Region was 28.11,and the lowest in 2009 was 17.75.From 2001 to 2019,the average per capita disposable income of urban residents in Inner Mongolia was 20085.89 yuan,and the average per capita disposable income of pastoral areas was 7,329.22 yuan.The per capita disposable income gap was 36%.The per capita disposable income of urban residents increased by668.62%from 2001 to 2019,and the per capita disposable income of pastoral areas increased by 659.24%from 2001 to 2019.In 19 years,the income gap between urban and rural residents in Inner Mongolia increased from a difference of 3,292 yuan in 2001 to a difference of 25,499 yuan in 2019,with an annual growth rate of 33.72%.The average number of scientific and technological personnel in Inner Mongolia from 2001 to 2019 was 7,277.The number of scientific and technological personnel in Inner Mongolia Autonomous Region decreased from 12,249 in 2001 to 5,900 in 2019,a decrease of 51.83%.Hohhot City had the highest average technology content of China Animal Husbandry among all league cities in Inner Mongolia,with 465.48,and Xing’an League had the lowest average technology content of 19.36,accounting for only 4.16%of Hohhot.(4)Comprehensive evaluation of the construction level of the beautiful pastoral area:The average value of the comprehensive evaluation index for the construction of the beautiful pastoral area in Inner Mongolia from 2001 to 2019 was 27.48,and the overall trend was increasing,from 30.68 in 2001 to 36.73 in 2019,an increase of 19.72%in 2016 The largest comprehensive beauty index of pastoral areas in Inner Mongolia was 39.3,and the lowest in2012 was 21.09.From 2001 to 2019,the average value of the comprehensive evaluation index for the construction of beautiful pastoral areas in Inner Mongolia’s leagues was between 9.74and 77.31.The pastoral area of Xilin Gol League had the highest comprehensive beauty index and Tongliao City had the lowest.Only 12.6%of Xilin Gol League.(5)Recommendations for the construction of beautiful pastoral areas in Inner Mongolia:All leagues and cities should combine local grassland resource endowments,and with the support of national policies,promote the rational allocation of animal husbandry production spatially;strive to maintain the balance of grassland resource supply for animal husbandry development and increase grassland resources.Broaden the channels for increasing herdsmen’s income,and improve the quality of life of herders;continue to improve the construction and release of the evaluation index system and evaluation for the construction of beautiful pastoral areas Standards,to carry out dynamic research on the construction of beautiful pastoral areas.Vigorously promote the construction of the beautiful pastoral area as an important part of the beautiful China pattern,and build a beautiful ecological barrier scenery line in the north of the motherland!... |
