【摘要】 在综合分析水环境承载力概念的基础上,结合河南省水环境现状,从水资源、水生态和社会经济3个方面考察水环境承载力,构建河南省水环境承载力评价指标体系,采用层次分析法计算各项指标的权重,并采用向量模法对河南省水环境承载力进行定量评价。计算结果表明,从2007-2016年,河南省水环境承载力基本上在逐年增加,但总体上还是处于中低水平,水资源紧缺是限制河南省水环境承载力的关键因素。更多还原

【Abstract】 Based on the comprehensive analysis of the concept of water environment carrying capacity and the current situation of water environment in Henan province,the carrying capacity of water environment was investigated from three aspects of water resources,water ecology and social economy,and the index system of carrying capacity of water environment in Henan province was constructed. The weight of each index was calculated by AHP and the carrying capacity of water environment in Henan province was quantitatively evaluated by vector model method. The results show that from 2007 to 2016,the carrying capacity of water environment in Henan province basically increased year by year. But overall it is still at a low level,water shortage is the key factor limiting the water environment carrying capacity of Henan Province.更多还原
