Abstract:: In order to boost up the applicability and guidance of the third level of national regionalization in Yunnan Province and thus to prevent and manage effectively soil and water conservation in the province. In virtue of the multivariate data, we deeply explored the four regionalization of soil and water conservation in Yunnan Province. According to the characteristics of soil erosion in Yunnan Province, there are 86 indicators including natural, socio-economic, land use and soil erosion which were selected in the index system. All indicators in the index system were analyzed using principal component analysis and cluster analysis by SPSS software, then with the help of GIS, it turned the result of cluster analysis into the distribution of map about four major factors, namely nature, socio-economic, land use and soil erosion. The four maps were used for spatial overlay analysis, the Yunnan Province soil and water conservation comprehensive evaluation map was preliminarily received. This method can greatly improve the efficiency and accuracy of the regionalization of soil and water conservation in Yunnan Province, and provide reference for the different levels of the regionalization of soil and water conservation work.
