摘　　要：地下水是新疆天山北坡平原区生活用水、工业用水及灌溉用水的主要水源。依据2011年77个地下水样的pH值、总溶解固体(TDS)、总硬度、氨氮、NO2-、NO3-、高锰酸盐指数、F-、Cl-、SO42-检测结果,采用单项指标评价法进行地下水质量评价,统计了各地各评价指标在不同水质级别所占的比例;采用化学组分浓度对比法对同一监测井2003年和2011年的18组水样进行地下水污染评价,分析了水质变化趋势和地下水污染原因。结果表明:2011年潜水和承压水中Ⅳ类和Ⅴ类水质所占比例之和分别为40.0%和47.6%;潜水水质类别基本呈现变好的趋势,而承压水水质类别呈现变差趋势。Groundwater is one of the important water sources of domestic water,industry water,and irrigation water in the plain area of northern slope of Tianshan Mountains in Xinjiang.Based on the pH,TDS,total hardness,ammonia,NO2-,NO3-,permanganate index,F-,Cl-,and SO42-values of 77 groundwater samples in 2011,the single factor method was used to evaluate groundwater quality and calculate the proportions of each evaluation index in different groundwater quality levels.Groundwater pollution was assessed based on 18 groundwater samples of the same observation well in 2003 and 2011using the chemical component concentration comparison method,and the variation trend of groundwater quality and causes of groundwater pollution were analyzed.The results showed that groundwater with quality level ofⅣ andⅤin the unconfined and confined aquifers accounts for 40.0% and 47.6%in 2011,and the water quality of unconfined aquifer improves while the water quality of confined aquifer deteriorates.
