Description :
The AA. studied the spatiotemporal features of soil and water loss in the Three Gorges Reservoir Area (TGRA) from 1999 to 2004 based on RS and GIS techniques. Results and discussion on the analysis of the correlation between soil and water loss and soil types, land use types, topography, rainfall. The aim of this paper is to further discuss the basic driving mechanism to the changes of soil and water loss, simulate and forecast soil and water loss in the TGRA and its response to eco-environment, so as to lay a foundation for establishing an effective mechanism to improve soil and water conservation and the eco-environmental quality in the TGRA.
