中文摘要：

干旱背景下的城市人居环境是一个复合生态系统,其影响因素具有多元性的特点,而气候因素和人文建设对城市人居环境的质量影响又具有双重性.因此,针对气候因素的多变性、模糊性和人文建设的层次性,运用模糊综合评价法（FCEM）和主成分分析法（PCA）对巴州地区的城市人居环境质量进行了评价,结果表明：模糊综合评价法和主成分分析法在分别对气候因素和人文建设定量评价方面效果较好.综合研究结果显示,库尔勒市人居环境最优,其次是和硕县与和静县,若羌和且末总体评价得分较低;巴州经济发展水平、生态建设皆不平衡,而公共服务能力建设普遍较低.针对巴州地区人居环境质量状况及其差异提出了改善和优化人居环境的相关措施.
