| Abstract: | Based on translated data from remote sensing images in 1993 and 2005,under the help of GIS software,the vegetation coverage and landuse plan in Anding region of Dingxi City was calculated by means of remote sensing image.The land slope in the region was computed by raster Digital Elevation Model(DEM) and the soil erosion was graded.The results indicated that the area of forest and grassland,build land had increased significantly and water region increased slightly,arable land and unused land had decreased g... |
