| 摘 要： | 将水质标准、评价指标及其特征值作为物元，对评价标准及实测数据进行归一化后，得到模型的经典域、节域、权系数及关联度，进而建立了水质评价的物元模型，并将该模型应用到重庆市的水质评价中，与BP网络法取得了有较好的一致性，而且评价结果符合客观实际。

| Abstract: | The standards of water quality and the indexes for evaluating the water quality and its eigenvalue are made as matter element, after normalizing the evaluate standards and surveyed data, the sutra field and controlled field and weight coefficient and relating degree are obtained, meanwhile, the model for evaluating the water quality is built up, then this model is applied on evaluating the water quality in Chongqing city , it has coherence to the result of the method of BP-ANN, and the result accords to the objective fact. |
