生态价值视角下长江经济带农业绿色生态效率时空演变及其影响因素研究OACSTPCD
Study on Spatio-temporal Evolution and Influencing Factors of Agricultural Green Ecological Efficiency in Yangtze River Economic Belt from Perspective of Ecological Value
在农业生态系统服务价值(ESV)的基础上,采用基于非期望产出的超效率SBM模型,对2012-2021年长江经济带农业绿色生态效率进行了测算,实证研究了其时空演变规律及影响因素.结果表明:(1)长江经济带农业绿色生态效率呈现先降后升,2018年后保持平稳发展的态势,整体处于较高水平,区域差异明显,从均值来看表现为中游＞上游＞下游;(2)长江经济带各省市农业绿色生态效率值整体得到提高且较多地集中在较高值上,高低效率地区差距缩小,整体农业绿色生态效率值…查看全部>>
On the basis of the value of agricultural ecosystem services(ESV),the super-efficiency SBM model based on undesirable output was used to measure the agricultural green ecological efficiency in the Yangtze River Economic Belt from 2012 to 2021,and its spatio-temporal evolution law and influencing factors were empirically studied.The results show that:(1)The green ecological efficiency of agriculture in the Yangtze River Economic Belt decreased first and then …查看全部>>
