摘　　要：人类活动对地下水环境造成了严重影响。以驿城区地下水源地补给区为例,对该区地下水进行评价分析。采用水质评价和污染状况评价,并通过ArcGIS绘制超标因子污染分级图。结果表明:未污染水样有37组,占总水样的35.24%;被污染水样68组,占总水样的64.76%;主要超标因子为铁、锰和氨氮;主要污染原因有工业三废的排放、化肥和农药的过度使用、生活垃圾随意堆放和排放产生的污染及其他污染。Human activities have made serious impact on the groundwater environment.Taking the groundwater source replenishment area in Yicheng District as an example,the groundwater in the area is evaluated and analyzed.The water quality evaluation and pollution status evaluation are adopted,and the pollution grading map of the over-standard factors is drawn by ArcGIS.The results show that there are 37 groups of unpolluted water samples,accounting for 35.24%of the total water samples.68 groups of polluted water samples,accounting for 64.76% of the total water samples,and the main over-standard factors are iron,manganese and ammonia nitrogen.The main causes of pollution include:the discharge of industrial waste,the excessive use of fertilizers and pesticides in agriculture,the random stacking and discharge of household garbage and other pollution.
