"双碳"视域下内蒙古地区农业生态效率时空演进特征及影响因素研究
THE SPATIOTEMPORAL EVOLUTION CHARACTERISTICS AND INFLUENCING FACTORS OF AGRICULTURAL ECOLOGICAL EFFICIENCY IN INNER MONGOLIA FROM THE PERSPECTIVE OF"DUAL CARBON"
摘要
Abstract
One of the important sources of carbon emissions is agricultural production activities.Conducting research on agricultural ecological efficiency from the perspective of"dual carbon"and exploring ways to achieve higher agricultural ecological benefits at a lower resource cost is of great significance for promoting green and high-quality agricultural development.This research took Inner Mongolia Autonomous Region and its 12 leagues and cities as the research object,constructed a comprehensive evaluation index system for agricultural ecological efficiency,and used the global super efficiency SBM model and grey correlation analysis model to study the spatiotemporal changes and influencing factors of agricultural ecological efficiency from 2001 to 2022.The results showed that:(1)From 2001 to 2022,the agricultural ecological efficiency in Inner Mongolia Autonomous Region showed a"U"-shaped change of first decreasing and then increasing,which was basically consistent with the changes in carbon sink and carbon source ratios.(2)The development level of agricultural ecological efficiency varied among different league cities,with an overall fluctuating upward trend,generally showing a pattern of higher efficiency in the east than in the west and higher efficiency in the west than in the central region.Among them,Alxa league,Hulunbuir city,Chifeng city,and Tongliao city were the first level,Bayannur city,Wuhai city,Xing'an league,and Xilingol league were the second level,and Hohhot city,Baotou city,Ordos city,and Ulanqab city were the third level.(3)The correlation between the per capita arable land scale,fertilizer intensity,industrialization level,proportion of agricultural output value,disposable income of rural residents,per capita GDP and agricultural ecological efficiency was relatively high,with values of 0.7751,0.7525,0.7041,0.6724,0.6634,and 0.6458,respectively.Therefore,in the future,Inner Mongolia Autonomous Region should explore its own agricultural development priorities based on the resource endowment characteristics of each league and city,gradually alleviate the contradictions of internal unbalanced development,accurately grasp the key factors affecting agricultural ecological efficiency,and effectively improve the overall level of agricultural ecological efficiency.关键词
