模糊综合评判法在淮南市浅层地下水评价中的应用

Application on Fuzzy Comprehensive Evaluation Method in Shallow Groundwater Evaluation of Huainan City

通过对淮南市浅层地下水水样进行测试、分析,选取氯离子、硫酸盐、硝酸盐氮、总磷、锰、铅等六项指标为评价指标,依据《地表水环境质量标准》(GB3838-2002),运用模糊综合评判法对研究区水质进行了合理评价。研究结果表明:淮南市浅层地下水综合水质较差,大部分地区浅层地下水已遭受到不同程度污染,多数水体不能直接作为饮用水。

Based on the result of shallow groundwater samples test and analysis,six indicators including Cl-、SO42-、NO3-、P、Mn、Pb were selected as proxies index for the quality of shallow groundwater in Huainan.According to the environmental quality standards of groundwater,the quality of shallow groundwater in Huainan was properly evaluated by the fuzzy comprehensive evaluation method.The results show that the integrative quality of shallow groundwater in Huainan is poor.And in most parts of the study area,shallow groundwater has been polluted in different extend so that a lot of water cannot be drink directly.This evaluation makes the quality characteristics of groundwater in Huainan clearer and provides scientific data for water resources protection and planning.
