| 摘 要： | 地下水的水质分析与污染评价是地下水保护与污染控制的重要内容。参照区域背景含量和国家地下水环境质量标准，运用模糊数学的方法对该地区地下水中NH4+、NO3-、CL-、总硬度、NO2-、COD、Fe、F-、Cr6+九种组分的分析结果进行了数据处理，并在此基础上，将该区地下水按水质好坏划分为五个等级，其中区内大部分地区属于水质较好的级地下水分布区。受人类活动影响，水质最差的五级地下水主要分布在工厂和居民区集中的地区。

| Abstract: | The background analysis and pollution evaluation of groundwater is an important content of environmental protection and pollution control.Referring to the background content of the ground water and the National Environmental Quality Standards of Groundwater, fuzzy mathematics was used as a way to proceed the analyzed data of NH4+, NO3-, CL-, total hardness, NO2-, COD, Fe, F- and Cr6+.Based on this the water quality was divided into five levels.Most of this area belongs to Ⅱ, where the water quality is better.Because of the influence of human’s activity, the Ⅴ water, which is the worst, mostly distributes in factories and residential area. |
