摘　　要：利用格兰杰因果检验优化下的数据包络分析方法,评估抚仙湖流域2010—2022年土地利用的生态效率,为实现土地利用投入最小化、产出最大化、生态效率最大化,提出土地利用优化方案.结果表明:抚仙湖流域2010—2022年的土地利用生态效率整体保持有效,呈现良好发展态势;2011、2013、2014、2017、2018、2020、2021、2022年,这8年均为DEA强有效,综合效益和规模效益均为1,土地利用生态效率达到最优,其余5年为非DEA有效.因此,推动技术创新与进步是促进抚仙湖流域土地利用效率提升的关键因素.应结合未来土地利用规划,优化投入和产出,注重提高技术创新与进步,提升土地利用的生态效率,实现经济发展与生态效益的双赢.The aim of the article is to assess the ecological efficiency of land use in the Fuxian Lake Basin from 2010 to 2022 through the data envelopment analysis method(DEA)optimized by Granger causality test,and to propose a land use optimization scheme in order to achieve the minimization of land use inputs,the maximization of outputs and the maximization of ecoefficiency.The results show that the overall ecological efficiency of land use in the Fuxian Lake Basin from 2010 to 2022 remained effective,showing a good development trend.In the years 2011,2013,2014,2017,2018,2020,2021,and 2022 in the Fuxian Lake Basin,the DEA was strongly efficient with both comprehensive efficiency and scale efficiency reaching 1,indicating optimal ecological efficiency of land use.The remaining 5 years were inefficient in DEA.Therefore,Promoting technological innovation and progress is a key factor in promoting land use efficiency in the Fuxian Lake Basin,combining the future land use planning,optimizing inputs and outputs,focusing on technological innovation and progress are essential to the ecologically efficient land use,and achieving a win-win situation of economic development and ecological benefits.
