基于复合模糊物元-熵权组合模型的淮河干流健康综合评价

选取河流的物理特征、水文情势、水环境质量、生物多样性4个方面建立河流健康综合评价指标体系,构建基于复合模糊物元与熵权法的河流健康综合评估数学模型,对淮河干流关键断面进行实例应用研究.结果表明,淮河干流淮滨、王家坝、鲁台子与蚌埠4个关键河段的河流健康指数分别为0.470、0.435、0.462和0.432,河流综合健康水...

Comprehensive health evaluation of Huaihe River mainstream based on compound fuzzy matter element-entropy weight combination model

A comprehensive evaluation index system of river health was established from four aspects, including physical characteristics, hydrological regime, water environment quality and biodiversity. A mathematical model for comprehensive evaluation of river health was established based on composite fuzzy matter element and entropy weight method. A case study on the key sections of Huaihe River mainstream was carried out. The results show that the river health indexes of the four key sections of Huaibin, Wangjiaba, Lutaizi, and Bengbu in Huaihe River mainstream are 0. 470, 0. 435, 0. 462, and 0. 432, respectively. The comprehensive health level of the river is not high as a whole, showing a downward trend from upstream to downstream. Due to the influence of national policies and human activities, the health of the river of Lutaizi section has increased significantly.
