山西省耕地利用生态效率时空演变及障碍因素研究
Study on the Spatiotemporal Evolution and Obstacle Factors of Ecological Efficiency of Cultivated Land Use in Shanxi Province
摘要
Abstract
Based on panel data from 11 cities in Shanxi Province from 2016 to 2023,this study uses the unex-pected output super-efficient SBM model and obstacle degree model to explore the spatiotemporal evolution and obstacle factors of ecological efficiency of cultivated land use in Shanxi Province.The results show that:(1)the overall ecological efficiency of cultivated land use in Shanxi Province shows a fluctuating growth trend,and each city has achieved a leap from low to high efficiency,gradually narrowing the regional gap;(2)The spa-tial distribution of ecological efficiency of cultivated land use in Shanxi P rovince has gradually evolved from a polarized distribution of"high in the north and south,low in the middle"in the early stage to a distribution characteristic of overall balanced optimization,and the spatial synergy continues to strengthen;(3)Labor in-put,land input,and agricultural machinery input are the main obstacles to improving the ecological efficiency of farmland utilization in Shanxi Province.The regional differentiation of obstacles in various cities is signifi-cant,forming a pattern of cross constraint of multiple factors such as land,agricultural machinery,labor,and irrigation.Therefore,it is proposed to promote coordinated development of regional economy and strengthen the synergy of ecological efficiency;optimize factor input and agricultural industry structure,and build a solid foundation for improving ecological efficiency;implementing differentiated and precise policies,breaking through regional barriers and bottlenecks,so as to provide a theoretical basis for the sustainable use of cultivat-ed land in Shanxi Province.关键词
