摘    要:本文在物元分析理论的基础上,将水质量标准、评价指标及其特征值作为物元,并以苏州市第Ⅱ承压地下水为例进行了水质评价。通过建立评价模型,对评价标准及实测数据进行归一化,得到模型的经典域、节域、权系数及关联度,评价结果表明,苏州市大部分第Ⅱ承压地下水水质优良,达到了Ⅰ、Ⅱ类水,未遭受外来物质的污染,评价结果符合实际情况。

关 键 词:水质评价  物元法  苏州市  第Ⅱ承压地下水

Abstract:Based on the matter element theory, this paper discussed the standards of water quality, the in- dexes for evaluating the water quality and its value as matter element, taking Suzhou city as evaluation example, constructed the evaluation model and normalized the evaluation standard and testing data to obtain the sutra field, controlled field, weight coefficient and relating degree of the model. The results showed that the quality of the greater part of second confined groundwater in Suzhou city is excellent, reaching to the first, second grade level, is not yet polluted by outer material, the results conform to reality.
Keywords::water quality evaluation  matter element method  Suzhou city  the second confined groundwater
