南淝河水环境质量的物元分析综合评价

Comprehensive Assessment of the Water Environment Quality of the South Feihe River Using the Matter Element Analysis Method

将水质标准、评价标准及其特征值作为物元,对评价标准和水质指标实测值进行标准化处理后,得到模型的经典域物元、节域物元、权系数及关联度,进而建立了水质评价模型,并运用该模型对南淝河水环境质量进行综合评价,与密切值法评价结果比较,取得了较好的一致性,表明该法切实可行.

The standards of water quality and the indexes for evaluating the water quality and its Eigen value are made as matter element, after normalizing the evaluated standards and surveyed data, the sutra field, controlled field, weight coefficient and relating degree are obtained. Meanwhile, the model for evaluating the water quality is built up, and then the model is applied on evaluating the water quality of the South Feihe River in the city of Hefei, which has coherence to the result of the method of the intimate data method and indieates that the presented method is practical.
