Abstract: It is of great significance to conduct some research on the change of ecosystem services value, via the reseach on the change of the land use, in order to provide reference on land use layout, ecoenvironment protection and ecological recovery. Recently, the status of land use in Dongting Lake Area fluctuates frequently. The research on the dynamic ecosystem services value may provide suggestions on the ecorehabilitation in this area. Based on table of Chinese ecosystem service value per unit area of different ecosystem types and on the land use change data of Dongting Lake Area, the ecological assets were divided into 7 types; the ecological value coefficients were set and the research on the change of ecosystem services value (ESV) was carried out during the time from 1980 to 2000s. The result shows that: (1) If defining the 1980 as the midpoint, the former decade had a decline of ESV, while the latter an increase, indicating the achievement of ecosystem construction of the area. (2)The change of wetland's ESV determined the change of the whole ESV of the Dongting Lake; the water area ESV dominated the main portion of ESV in the whole area.
