    摘要:

    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,河流综合健康水平整体不高,自上游到下游呈下降趋势,由于国家政策和人类活动影响,鲁台子河段的河流健康状况明显升高。

    Abstract:

    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.
