摘　　要：【目的】对喀什市生态环境敏感性评价及驱动力进行分析,为制定科学合理的生态环境保护与可持续发展策略提供参考。【方法】以GIS为技术支撑,利用层次分析法(AHP),建立生态环境敏感性综合评价体系,对喀什市进行生态环境敏感性评价。首先对高程、坡度、坡向、植被覆盖度、水体缓冲区、道路缓冲区、居民点距离和土地利用类型等8个生态敏感性评价因子进行评价;其次运用加权平均的方法计算出综合生态敏感性;最后,采取自然间断点法进行生态敏感性分区,得到喀什市综合生态环境敏感性分布图。【结果】结果表明,喀什市生态环境敏感性以不敏感、轻度敏感和中度敏感为主,极敏感区域、高敏感区域、中敏感区域、低敏感区域、极低敏感区域面积占比分别为26.47%、27.32%、23.30%、15.79%、6.83%。中度敏感及以上区域主要分布在北部和西部,东部有少部分,其余部分为不敏感和轻度敏感。从地理探测器结果可知,植被覆盖度是喀什市生态敏感性发生变化的主要驱动力因素。【结论】研究结果有助于加深对喀什市生态敏感性格局的理解,可为生态风险评估和可持续发展策略的制定提供有力支持。[Purposes]This paper analyzes the sensitivity assessment and driving forces of the ecological environment in Kashi City,providing theoretical basis for formulating scientific and reasonable strategies for ecological environment protection and sustainable development.[Methods]Based on GIS technology and utilizing Analytic Hierarchy Process(AHP),a comprehensive evaluation system for ecological environment sensitivity is established to conduct an ecological environment sensitivity assessment of Kashi City.Firstly,this paper evaluates 8 ecological sensitivity evaluation factors including elevation,slope,aspect,vegetation coverage,water buffer zone,road buffer zone,residential distance,and land use type;then,this paper uses the weighted average method to calculate the comprehensive ecological sensitivity;finally,the natural discontinuity method was adopted for ecological sensitivity zoning,and a comprehensive ecological environment sensitivity distribution map of Kashi City was created.[Findings]The research results indicate that the ecological environment sensitivity of Kashi City is mainly insensitive,mildly sensitive,and moderately sensitive.The areas of extremely sensitive,highly sensitive,moderately sensitive,low sensitive,and extremely low sensitive areas account for 26.47%,27.32%,23.30%,15.79%,and 6.83%,respectively.Moderately sensitive and above areas are mainly distributed in the north and west,with a small portion in the east,and the rest being insensitive and mildly sensitive.According to the results of the geographic detector,vegetation coverage is the main driving factor for changes in ecological sensitivity in Kashi City.[Conclusions]The results are conductive to deepening the understanding of the ecological sensitivity pattern in Kashi City and provide strong support for future ecological risk assessment and the formulation of sustainable development strategies.
