摘　　要：利用焦作地区88个监测孔水质指标检测结果,采用模糊综合评价法对焦作地区浅层地下水中硝酸盐氮、溶解性总固体、硫酸盐、硬度、六价铬、氟化物、镍离子、氨氮、氯化物共9个指标进行评价。通过建立因子集、评价集、隶属度集、模糊权向量矩阵,进行模糊综合运算最终确定研究区浅层地下水水质的级别。评价结果表明,研究区浅层地下水质很差,污染率高达81.82%,其中,劣Ⅴ类水质高达26.14%,主要分布于北部的大家作、小尚、北敬村以及南部的任庄、小王庄、南李村一带,与工业污染源、农业污染源和生活污染源分布具有一致性。Based on the detected water quality indexes of Jiaozuo Area from 88monitor holes,this paper evaluates nine groundwater quality indexes including nitrate nitrogen,total soluble solid,sulfate,hardness,hexavalent chromium,fluoride,nickel ion,ammonia nitrogen and chloride by using the fuzzy comprehensive evaluation method.The water quality level of shallow groundwater is finally established by establishing factor sets,evaluation sets,membership sets and fuzzy weight vector matrix,and carrying on fuzzy comprehensive evaluation.The results show that the shallow underground water quality of research area is poor,pollution rate is as high as 81.82%.Among them,the five poor types of water quality reach as high as 26.14%,mainly distributed in northern Dajiazuo Village,Xiaoshang Village,Beijing Village and south of Ren Village,Xiaowang Village and Nanli Village,which are consistent with the distribution of industrial pollution sources,agricultural pollution sources and domestic pollution sources.
