| Abstract: | Taking Pengyang County as an example,according to the principles of returning cropland to forest(grass),how to scientifically and reasonably choose forest and grass model of returning cropland to forest(grass) in Pengyang County was discussed based on GIS.Through the research method of spatial analysis of GIS,the proportion of forest to grass,the area and distribution of cropland were anglicized under the conditions of soil erosion,slope,river,and the suitable mode was found.GIS technology provided valid me... |
