| 摘 要： | 水环境质量评价是水环境保护和治理工作中的一项重要任务。应用熵权法来确定评价指标的权重，建立了基于熵权的水环境质量评价物元分析模型，对重庆市凤嘴江的水环境质量进行了评价，并与传统物元分析方法和BP网络法进行对比。结果表明，该方法的评价结论合理，用熵权法确定评价指标的权重客观、计算简便。

| Abstract: | The evaluation of water environmental quality plays an important part in the protection and control job of water environment. Matter element analysis model based on entropy weight is proposed. The Fengzui river of Chongqing city is taken as an example for applying to evaluate the water environmental quality. The results are compared with that of the traditional matter element analysis method and BP networks. It shows that the proposed model is reasonable, and that the entropy weight method is objective and convenient in calculation. |
