| 摘 要： | 首次运用均方差-模糊综合评判复合模型,选取地下水水质的主要影响因子,通过评价因子的选取及评价集的建立、隶属函数及单因子隶属度的确定、评价指标权重的确定和综合隶属度的确定四个步骤,对天津蓟县官庄地区深层地下水水质行了综合评价.评价结果表明,研究区采样点水质总体级别为I级,说明该区地下水水质较好,而局部点位硝酸盐超标是导致水质污染的主要原因,这一结论与该区其它研究成果评价结果相一致.

| Abstract: | The multi-model of mean square deviation and fuzzy synthetic Judgments is firstly used to evaluate the deeper groundwater quality of Guan-zhuang in Jixian,by choosing the major affected factors.The result shows that the groundwater quality of samples in the area is all in grade I and in a state of better.While super-standard of nitrate is the reason leading to pollution of groundwater.The conclusion is approximately uniform with that before.It was proved that the multi-model of mean square deviation and fuz... |
