| Abstract: | Soil erosion is first environmental problem and an important national disaster in Jinsha River Basin of Yunnan Province. In the paper, the author selects 8 index, and uses the method of fuzzy cluster analysis for regionalizing soil erosion disaster in Jinsha River Basin of Yunnan province. As a result of the regionalization, the paper divides the Basin into three regions and nine subregion of soil erosion disaster. The study on the regionalization has revealed the regional differences of soil erosion disaster in the Basin, and may provide scientific bases for mapping out the planning of preventing and controlling soil erosion disaster and the measures of disaster reduction in the light of local conditions. |
