摘要: 模糊数学综合评判法在地下水环境质量评价过程中存在隶属度和多指标综合运算规则选取等问题，该文结合地下水标准修正隶属度函数应用于晋江市地下水质量评价，并对比分析了修正后的4种运算规则的模糊数学综合评价结果及其内梅罗指数评价法结果存在的异同性，结合GIS技术与地统计，给出了研究区“加权平均型”地下水环境质量综合评价数字地面模型，分析结果得出目标区地下水环境质量综合评价结果整体处于良好水平，说明修正后的模型能更真实地反映地下水水质状况，有较高的应用价值。Abstract: There are problems of membership and multi index comprehensive operation rule selection in the application of fuzzy comprehensive mathematics evaluation method in the groundwater environmental quali-ty assessment process .Combined with groundwater standard and the application of the modified member-ship function in the groundwater quality evaluation of Jinjiang City ,this paper makes a comparative analy-sis of the similarities and the differences between the results of the fuzzy mathematical comprehensive eval-uation based on the modified four kinds of operation rules and the results based on the Nemerow index e-valuation method .And combined with GIS technology and geostatistics ,this paper gives the digital terrain model for the“weighted average” comprehensive evaluation of groundwater environment quality .The re-sults of the analysis reveal that the overall environment quality of the ground water in the target area is in good condition ,and the revised model has a higher application value because it can more truly reflect groundwater quality .
