地下水是南疆5地(州)生活用水及灌溉用水的重要来源.在南疆5地(州)采集了104个地下水样,测定其pH值、总溶解固体、总硬度、氨氮、NO2-、NO3-、高锰酸盐指数、F、Cl-、SO42-,采用一票否决法对各取样点的地下水水质进行了评价,进而完成了地下水水质等级分区,统计了各地(州)各评价指标在不同水质级别中所占的比例.分析结果表明,该区地下水天然水质较差,并存在人为污染.据此提出了防治地下水污染的4条建议.%Groundwater is an important resource of domestic water and irrigation water in the five administrative prefectures of southern Xinjiang. The 104 groundwater samples of the five administrative prefectures were collected and their value of pH, TDS,total hardness,ammonia und nitrogen,NO-2 , NO-3 >permanganate index,F- ,C1- and S24- were tested,groundwater quality of sampling points was evaluated by method of only one negative vote,to distinguish the groundwater quality level,and count proportion of the evaluation indexes in different quality levels in the five administrative prefectures. The results showed that the natural quality of groundwater in the study area is poor,and there is the artificial pollution. Accordingly four proposals in prevention of groundwater contamination were put forward.
