In Dongting Lake area,because of human's unreasonable exploitation and utilization,the wetland's ecosystem degeneration and ecological value decline occurred,resulting in serious effect to regional economic sustainable development.Lake recovery is a main method to renew the ecological function of the wetland ecosystem.In this paper,the eco-economic theory and a range of evaluation methods are applied,which capture different components of the total economic value(TEV)based on the investigations and experiments for the purpose of evaluating the eco-economic benefit of the lake recovery skills.The main evaluation methods include:the method of tax rate of Sweden researching value,travel consumption method,Robert Constanza method,market value method and assets value method.The conclusion shows that the total assets value of the wetland resources in the Lake Recovery area is690214.13×10 4 $RMB,which is about four times that of before.The result suggests that renewing the wetland ecological environment,protecting the wetland resources and carrying out the assets management of the wetland resources in Dongting Lake area are the effective ways to realize the sustainable utilization of the wetland resources and to guarantee the sustainable development of the regional economy around the Dongting Lake area.
