Studying land use change and its spatial expansion along the terrain gradient is of great significance for identifying the direction of land use change and its sustainable use. In this paper, a case study is conducted in Banxi village, Youyang county, Chongqing City. The major aims is to study the characteristics of land use pattern in the region and provide reference for adjusting land use structure and ecologic reconstruction in similar karst areas. Overall, the expansion forest land enables rocky desertification at high terrain to be controlled to some extent. In order to realize reforestation and ecological environment improvement quickly, dominant tree species at scrublands should be fostered and economic forest trees should be inter-planted in still preserved slope cropland focuses in 2011.
