【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 enhance the applicability and guidance of the three-level regionalization of soil and water conservation in Yunnan Province, the prevention and control of soil and water conservation can be carried out more effectively. The index system of soil and water conservation regionalization in Yunnan Province was constructed by selecting 86 indexes of four factors of nature, social economy, land use, and soil and water conservation in view of the division of soil and water conservation in Yunnan Province. The principal component analysis and cluster analysis of the index system were carried out by SPSS software, and the results of cluster analysis were plotted into natural factor distribution map, social and economic factor distribution map, land use factor distribution map and soil and water conservation factor distribution map combined with GIS software. The spatial overlay of the distribution maps of the four elements was used to preliminarily complete the work of four levels of soil and water conservation zonation in Yunnan Province. This method greatly improves the efficiency and accuracy of soil and water conservation regionalization, in order to provide reference for different levels of soil and water conservation regionalization.
