| 摘 要： | 为了增强全国水土保持三级区划在云南省的适用性和指导性，更有效地开展水土保持预防治理工作。针对云南省开展水土保持四级区划，选取自然、社会经济、土地利用、水土保持4类要素的86个指标构建了云南省水土保持区划指标体系，通过SPSS软件对指标体系进行主成分分析和聚类分析，结合GIS软件将聚类分析结果绘制成自然要素分布图、社会经济要素分布图、土地利用要素分布图、水土保持要素分布图，并对这4个要素分布图进行空间叠置，初步完成了云南省水土保持四级分区工作。该方法大大提高水土保持区划的效率和准确性，以期为不同层次水土保持区划工作提供借鉴。

| 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. |
