中文摘要	本文以新疆阜康三工河流域为研究区域，分析了干旱区陆流域的景观生态的基本特点。在此基础上，基于景观格局构造了景观损失系数和综合风险指数作为区域景观生态风险评价指标，并利用空间分析方法对风险指数进行变量空间化，通过对生态风险指数采样结果进行半方差分析和空间插值，揭示了该区域的生态环境状况的空间分布特征。结果表明：研究区内的生态风险有不断扩大的趋势，区域内形成三个高的景观生态风险区域。根据评价结果，提出了内陆流域生态环境的重点保护与治理区以及合理的保护与综合整治对策。
英文摘要	In this paper, Sangong River Basin in Fukang was selected for case study. The landscape ecological characteristics of the inland river watershed of arid area were analyzed. Based on the landscape struc-ture, the authors brought forward indexes and formulas to measure landscape damage degree and risk value of ecosystem. The system sampling method was used to make it a spatial variance, and the semivariagram analysis and block Kriging were conducted to explore the spatial characteristics and distribution of landscape ecological risk in the study area. The results indicated that the ecological risk in the study area tends to extend, and three belt areas with high ecological risk were formed in this region. Based on the results, the most important regions of eco-environmental protection in the study area were determined, and the management countermeasures of eco-environmental protection and strategies were put forward.
