| Abstract: | As a case study in Jiangxi province, the eco-environment factors which affect soil and water loss are chosen. Then each factor is given avalue by soil erosion formula, and gotten a weight by adopt PCA method. The risk degree of soil and water loss are divided, and the results are analyzed. |
