%X Today, more and more research has focused on the issues of Global Environmental Change(GEC) and sustainable development(SD), and the study of land use/ cover change is a hot subject and front issue among all the researches. The serious eco-environment problems have been an obstacle to the economic and social development in upper reach of Yangtze River Basin, and the natural degradation also restricts the sustainable development for upper reach and all regions of Yangtze River Basin. Based on the DEM data, this paper analyzed the relationship of land use with elevation, slope and aspect in 2000. It is discovered in the result that the types of land use in upper reach of Yangtze River Basin in 2000 changed with different grade of elevation, slope and aspect. It is also indicated that these topographical factors have important influence on land use in upper reach of Yangtze River Basin. In order to protect the e-co-environment and to promote the sustainable development in the upper reach and all regions of Yangtze River Basin, land use management should be enhanced based on the local condition. And further research should be developed to optimize land use and improve land cover with the influenced factors such as elevation, slope and aspect.
