Based on the remote sensing images of 1987, 1993 and 2000, the wetland spatial database in Zhangdu watershed was built up and the images were interpreted as supported by GIS. After an analysis on the change of the wetland in Zhangdu Watershed, the authors explained the reason for wetland change from the point of human activities. Three essential conclusions are drawn as follows: Firstly, wetland is the main land use form in Zhangdu Watershed; Secondly, natural wetland and artificial wetland decreased from 1987 to 2000, and the water land area decreased most; Thirdly, the factor that affects the change of wetland in Zhangdu Watershed is adjustment of industry and urbanization.
