中文摘要：

依据《农村饮用水安全卫生评价指标体系》,采用单因子评价法对新疆喀什地区东部叶尔羌河流域农村地区地 下水水质安全进行评价.结果表明：叶尔羌河流域平原区1 4组潜水水样中,水质安全类别为安全、基本安全、不安全的 分别占14.3%、 7.1%、 78.6%;51组浅层承压水水样中,水质安全类别为安全、基本安全、不安全的分别占3 .9% 、 7 .8% 、 88.3% ;6 组深层承压水水样水质安全类别均为不安全.研究区农村地区地下水水质较差,但研究区山前倾斜平原的地 下水水质相较于叶尔羌河流域中下游的地下水水质要稍好一些;在垂向分布上,潜水水质优于承压水水质,浅层承压水 水质优于深层承压水水质;研究区农村地区地下水水质较差主要受气候、土壤、地貌及生活、工业活动等影响.

英文摘要：

According to the “Safety and Sanitation Evaluation Index System of Rural Drinking Water”, this study used the single-factor eval-uation method to evaluate groundwater quality security in rural areas of Yarkant River basin in eastern Kashi region. The results show that the quality security categories of phreatic water wells are safe,basically safe and unsafe,accounting for 14 .3%, 7.1% and 78.6% respectively of the 14 investigated wells; the quality security categories of shallow confined water wells are safe,basically safe and unsafe,accounting for 3.9%,7.8% and 88.3% respectively of the 51 investigated wells; the quality security categories of six deep confined water wells are all un-safe. The quality of groundwater is poorer in rural areas, but the quality of groundwater in the piedmont sloping plain is better than that in the middle and lower reaches of Yarkant River. Vertically, the quality of unconfined groundwater is better than that of the confined groundwater, and the quality of shallow confined groundwater is better than that of the deep confined groundwater. The arid climatic conditions,landform, soil, living pollution and industry pollution are the major factors of poor groundwater quality.
