摘　　要：揭示喀什市发展建设过程中景观生态风险的特征,以便为区域规划发展提供决策。数据源以2020年第三次全国土地调查初步成果,采用生态风险指数和空间分析方法(半方差分析法和克里金插值法)将研究区域分为低、较低、中等、较高和高风险区5类,得到生态风险分布图。研究表明:喀什市态风险指数空间分布主要呈环带状,高风险区主要位于无人区,低风险区主要位于喀什市城区和其余地区的过渡地区。In order to reveal the characteristics of landscape ecological risk in the process of development and construction of Kashi City, so as to provide decision-making for regional planning and development.Taking the preliminary results of the third national land survey in 2020 as the data source, this paper uses ecological risk index and spatial analysis methods(semi variance analysis and Kriging interpolation)to divide the research area into five categories: low, low, medium, high and high risk areas, and obtains the ecological risk distribution map. The research shows that the spatial distribution of risk index in Kashi City is mainly circular and banded, the high-risk area is mainly located in no man′s land, the lowrisk area is mainly located in the transition area between the urban area of Kashi City and other areas.
