Measurement Of Carbon Emission Efficiency In Agriculture And Rural Areas In Henan Province Analysis Of Influencing Factors

Climate change has become an important factor limiting the sustainable development of human society,and how to effectively control greenhouse gas emissions to slow down the global warming trend is a major issue of common concern and urgent need to be solved by the whole global society.2021,the fourth session of the 13th National People’s Congress announced the development goals of the 14th Five-Year Plan,which emphasizes To achieve carbon peaking by 2030 and carbon neutrality by 2060.Since the 20th National People’s Congress was held,the government work report has again emphasized the need to actively and steadily promote carbon peaking and carbon neutrality,and in the context of this "double carbon" target,greenhouse gases from agriculture and rural areas cannot be ignored.Henan Province is the main grain-producing area in China,and as a large agricultural province,it plays an important role in the low-carbon development of agriculture and rural areas.The study of carbon emissions from agriculture and rural areas in Henan Province is intended to provide data support and theoretical reference for better promoting.the green development of low-carbon agriculture and the construction of beautiful Henan Province.In view of this,this thesis focuses on the characteristics of agricultural and rural carbon emission efficiency and its influencing factors in Henan Province:Firstly,the spatial and temporal characteristics of agricultural and rural carbon emissions of 18 cities in Henan Province during 2000-2020 were estimated by applying the IPCC method,and the results showed that the total agricultural and rural carbon emissions in Henan Province showed an inverted "U" curve trend of increasing and then decreasing,and the distribution of carbon emissions in each city was uneven,and the overall spatial pattern was gradually increasing from north to south and from west to east;Secondly,the Undersirable-Super-SBM model was used to measure the carbon emission efficiency of rural agriculture in Henan Province,and the spatial and temporal differences were investigated,which showed that the carbon emission efficiency level of rural agriculture in Henan Province showed a fluctuating upward trend,i.e.The results show that the efficiency level of agricultural and rural carbon emissions in Henan Province shows a fluctuating upward trend,i.e."rising-declining-slowly rising-rapidly rising",and the spatial pattern that the regions with good efficiency levels are distributed in the northwest and southeast,the cities with medium efficiency levels are the most numerous and concentrated in a row,and the cities with the lowest efficiency averages are sporadically distributed;Afterwards,the Tobit regression model empirically found that the level of urbanization and the effective irrigation rate promote the efficiency of rural agricultural carbon emissions,while the intensity of fertilizer use,agricultural machinery density,electricity consumption per unit of output value and crop planting structure inhibit the efficiency of rural agricultural carbon emissions;Finally,based on the above findings,this thesis proposes a series of countermeasures to improve the carbon emission efficiency of rural agriculture in Henan Province:to improve agricultural technology and increase energy saving and emission reduction;to strengthen the management of breeding process and promote the green transformation of animal husbandry;to promote the change of rural energy and realize the low-carbon development of rural areas;to increase scientific and technological innovation and build a scientific and technological support system.
