| Abstract: | On the basis of analyzing the major factors which effected soil erosion,these factors are interpreted using L andsat- 5 TM image.Meantime,all basic erosion pattern spots are interpreted according to comprehensive feature of soil erosion on TM images,too.Then, the grades of soil erosion are determined by a multi- factor and multi- level comprehensive judgment method.It also analyzes the present situation and the general devolping trend of soil erosion. |
