摘　　要：采用F值评分法对新疆昌吉州东部平原区2016年63组水样进行了地下水水质评价,结果表明:昌吉州东部平原区2016年地下水以Ⅲ类水为主,水质属良好级。在超标率统计中,除Cl-未超标外,Na^+、SO4^2-、TDS、TH含量存在超标的井点,超标率最高的化学组分为TH。同时,根据54组2012-2016年原位井水质监测数据对地下水质量时空分布规律及水质劣化原因进行了分析,结果表明:昌吉州东部平原区2012-2016年Ⅲ、Ⅳ类水分布面积逐渐增大,地下水水质整体呈劣化趋势,其中承压水水质劣化程度大于潜水的。地下水水质劣化受自然因素(包气带岩性、地下水补给)和人为因素(工业和生活污染、地下水开采)的影响。The F-value evaluation method was used to evaluate the water quality based on 63 groundwater samples of the eastern plains of Changji Hui Autonomous Prefecture of Xinjiang in 2016. The results showed that the groundwater quality classification was mainly class III and groundwater quality was good in 2016. Except Cl- did not exceed the water quality standard, others chemical composition of Na^+, SO2-4, TDS and TH of the well points that exceeded water quality standard. Chemical component with the highest rate of exceeding the standard was TH. At the same time, the spatial and temporal distribution law of groundwater quality and the cause of deterioration of groundwater quality were analyzed by collecting 54 in situ water quality monitoring data from 2012 to 2016. The results show that the distribution areas of class III and IV water quality are increasing and the groundwater quality shows deterioration trend from 2012 to 2016 in the study area. The deterioration degree of confined groundwater quality is greater than that of unconfined groundwater quality. The main reasons leading to deterioration of groundwater quality include natural factors(lithology of unsaturated zone and groundwater recharge) and human factors industrial and domestic pollution, groundwater exploitation.
