摘　　要：在分析水土流失分布特征、构建水土保持区划指标体系基础上,采用主成分分析、聚类分析及ArcGIS空间叠置等方法划定了昌吉州水土保持四级区划,即南部中高山冻融区、南部中低山丘陵水源涵养生态保护区、南部低山丘陵土壤保持区、中部绿洲人居环境农田防护区、北部荒漠生态维护防风治沙区、北部中低山水源涵养生态维护区,并提出了各分区水土流失防治布局。Based on analyzing the distribution characteristics of soil and water loss and building the index system of soil and water conservation regionalization,the paper delimited four-level divisions of soil and water conservation in Changji Prefecture by using the methods of principal component analysis,cluster analysis and ArcGIS spatial overlay methods,including the southern middle-high mountain freeze-thaw area,the southern middle-low mountain and hilly water conservation ecological protection area,the southern low mountain and hilly soil conservation area,the central oasis living environment and farmland protection area,the northern desert ecological maintenance windbreak and sand control area and the northern middle-low mountain water conservation ecological protection area.It also put forward the layout of soil erosion prevention and control in each sub-areas.
