摘　　要：巩义市城区地下水是巩义市城区重要的供水水源,为掌握其地下水的水质状况,为巩义市城区地下水资源利用提供依据,在巩义市城区布设8个地下水水质监测点,对巩义市城区2011年和2014年的地下水水质进行了监测,利用单因子指数法和综合指数法对监测数据汇总分析,确定了主要超标因子,并对地下水水质进行了评价。结果表明:该地区地下水中的主要超标因子为氨氮、亚硝酸盐氮、高锰酸钾、铁(Fe)、锌(Zn);且2011年巩义市城区地下水水质以Ⅱ类水为主,2014年多为Ⅳ类水,说明该地区水质呈现出逐渐恶化的趋势。The main water source of the urban area in Gongyi City is groundwater. To control the quality of groundwater and provide the basis for the utilization of groundwater resources, 8 monitoring stations were set in the urban area of Gongyi, and the groundwater quality in 2011 and 2014 were monitored. The monitoring data were analyzed by single factor index method and comprehensive index method. The main exceeding standard factors were analyzed, and the groundwater quality was evaluated. The results show that the main exceeding standard factors in the groundwater are ammonia nitrogen, nitrite nitrogen, potassium permanganate index, iron and zinc, and the groundwater quality is mainly in class Ⅱ water in 2011 while it is in class Ⅳ water in 2014. It is indicated that the groundwater quality in the urban area shows a trend of gradual deterioration.
