摘　　要：梳理华中地区农业绿色发展水平的时空演化特征,探究其区域差异,是分析区域农业绿色可持续发展的基础。采用熵值法和耦合协调度模型对华中地区2010—2020年47个地级市的农业绿色发展水平进行测度,分析其时空演化特征,并在此基础上进一步运用变异系数法探究区域差异。在时序变化上,农业绿色发展水平综合评价指数均值从0.233增长为0.376。在空间变化上,农业绿色发展水平处于快速发展和高速发展阶段的地级市数量越来越多,而且各地级市之间存在明显区域差异,具体表现为中北部和西北部地区农业绿色发展水平高于其他地区。2010—2020年华中地区各地级市农业绿色发展耦合协调度值整体呈上升趋势,耦合协调度值在0.100~0.500之间。变异系数从2010年的0.147下降为2020年的0.119,表明华中地区农业绿色发展水平整体区域差异逐渐降低。Exploring and sorting out the spatial and temporal evolutionary characteristics of the level of agricultural green development in central China and analyzing regional differences are the basis for the sustainable development of regional agricultural green development.In this paper,the entropy value method and the coupled coordination degree model are used to measure the level of agricultural green development in 47 prefecture-level cities in Central China from 2010 to 2020 and analyze their spatial and temporal evolution characteristics.On this basis,regional differences are further analyzed using the coefficient of variation method.In terms of temporal changes,the average value of the comprehensive evaluation index of agricultural green development level has increased from 0.233 to 0.376.In terms of spatial changes,the number of prefecture-level cities whose agricultural green development level is in the stage of rapid development and high-speed development is increasing,and there are obvious regional differences among municipalities,Specifically,the level of agricultural green development in the north-central region and northwest region is higher than that in other regions.Between 2010 and 2020,the coupling coordination degree value of agricultural green growth at each municipality in Central China showed an overall upward development trend,and it ranges from 0.100 to 0.500.The coefficient of variation decreased from 0.147 in 2010 to 0.119 in 2020,indicating that the overall regional difference in agricultural green development level in central China gradually decreases.
