%X This paper takes Luxiang town of Shuangyang district in Changchun city as study area. Based on SPOT5 remote sensing images and DWG full-factor relief map, NDVI was extracted and density was segmentated to indentify the vegetation-covered rate by remote sensing software. Meanwhile, the slope information was extracted from the DWG file by GIS software and degree the topography slope. According to the vegetation overlap degree, the topographic map and land use map, we identified the degree index of the soil erosion intensity,as a result, soil erosion map was gained.
