Abstract：Studying the ecological efficiency of land use in Dongting Lake Ecological Economic Zone can identify influencing factors and enhance wetland conservation effectiveness,providing insights for global wetland management.Based on the super-efficiency SBM model and the panel data of 24 regions in 2016-2020,this paper measures the ecological efficiency of land resources in each county(city,district);Based on stochastic frontier regression analysis(SFA),it analyzes the main factors affecting the ecological efficiency of urban land and its direction of action,and eliminates environmental factors and random interference items to obtain a more real ecological efficiency value.The empirical results show that the average initial ecological efficiency in the first phase of Dongting Lake from 2016 to 2020 is 1.0258,while the average adjusted ecological efficiency in the third phase is 0.9564.There is a significant difference between the results of the third phase and the first phase,indicating that environmental factors and random disturbances have a significant impact on the ecological efficiency of land.
