On basis of the interpreting of remote sensing data and overlaying of vector data

the distribution and change law of land use and cover with change of slope and aspect and the influences of the slope and aspect on the single dynamic change degree and comprehensive dynamic change degree were discussed by applying the function of GIS to manage the spatial and attribution data. The positive and negative effects of social driving force on the land use and cover dynamical changes were analyzed in this paper. The research results indicated that human activity

which is extending to terribly steep slope slowly

mainly centralized in the lower area. In Daninghe River watershed

steep and terribly steep slope farming land distributed too much and forest land distributed too little

which have a negative effect on environment.
