摘　　要：地下水水质评价是地下水污染防治和合理开发利用的基础,为解决“单指标最高类别法”存在的可能夸大水质恶劣程度、无法体现水质整体状况及无法区分同类别内水质优劣等局限性。采用模糊Borda法对济南市4处地下水水源地的综合污染指数法和主成分分析法的水质评价结果进行组合评价。结果表明,3种评价方法均能够体现水质整体状况,且能区分同类别水质的优劣程度,结果具有一致性。模糊Borda组合法可有效避免权重赋值对评价结果的影响,具有更高的区分度,在饮用水水源地的水质评价中具有较高的合理性和实用性。Groundwater quality evaluation is the basis for groundwater pollution prevention and control and rational development and utilization.In order to solve the limitations of the"single indicator highest category method"that may exaggerate the degree of water quality,fail to reflect the overall condition of water quality,and fail to distinguish the quality of water within the same category,the fuzzy Borda method was used to combine and evaluate the water quality evaluation results of the comprehensive pollution index method and the principal component analysis method of four groundwater sources in Jinan.The results show that all three evaluation methods can reflect the overall condition of water quality and distinguish the quality of water in the same category,and the results are consistent.The fuzzy Borda combination method can effectively avoid the influence of weight assignment on the evaluation results,has a higher degree of discrimination,and is more reasonable and practical in the water quality evaluation of drinking water sources.
