Fuzzy comprehensive assessment on Luanhe water environment based on information entropy

This article set up a surface water quality fuzzy evaluation model, information entropy is used to determine weight of each factor of effect water quality, and then fuzzy comprehensive assessment is developed to evaluate Luanhe downstream surface water environment. The results showed that the method solved weight distribution problem better, and more reasonable and reliable conclusions are made by this method. Predicting result is consistent with the local surface water environment. This result can provide the basis for surface water environment remediation on Luanhe downstream in the future.
