摘要: 地下水水质评价可为地下水资源开发利用与保护提供科学依据。针对传统水质评价法指标存在随机性、模糊性和不确定性等特点,根据蛤蟆通流域86个地下水监测数据,选取了NH4+,NO2-,Fe2+,Mn2+,Zn2+,CODMn6项能反映水质的指标体系,运用熵权法确定评价指标的权重,构建了基于熵权法的集对分析模型,并利用该模型对蛤蟆通流域地下水水质进行评价,并将评价结果与修正的内梅罗指数法的计算结果进行了对比分析。结果表明:蛤蟆通流域地下水水质中等偏下,Ⅳ,Ⅴ级水质的地下水分布占较大面积,而Ⅱ,Ⅲ级地下水分布所占面积较小。评价结果与修正的内梅罗指数评价法反映的水质特点具有一致性,与实际情况相符。可见基于熵权法的集对分析模型合理可靠。

Abstract: The evaluation of groundwater quality serves as a scientific basis for the exploitation and protection of groundwater resources. The indicators of traditional water quality assessment models are random, fuzzy and uncertain. In view of this, a set pair analysis model based on entropy method is established and applied to the groundwater quality assessment for Hamatong drainage basin. According to data of 86 monitoring points, six indicators, including NH4+, NO2-, Fe2+,Mn2+, Zn2+, and CODMn are selected and given weight by using entropy weight method. The assessment result is compared with that of modified Nemerow index method. The results implies that the groundwater quality of Hamatong drainage basin is below average, with Ⅳ and Ⅴ levels accounting for a large water area, while Ⅱ and Ⅲ levels occupying a small area. The assessment result is consistent with that of the modified Nemerow index method, both comforting well with reality. The set pair analysis model based on entropy weight is proved rational and reliable.

Key words: groundwater quality assessment, entropy weight, set pair analysis, comparative analysis, Hamatong drainage basin, water resources exploitation
