河南省水资源承载力空间差异分析

Spatial Difference Analysis of Water Resources Carrying Capacity in Henan Province

以河南省18个地市为研究对象,从水资源-社会-经济-生态复合大系统选取16个指标,基于熵权TOPSIS法对2018年河南省18个地市进行水资源承载力空间差异分析和综合评价。评价结果显示:2018年,河南省水资源承载力较弱,从空间差异看,南部地区属较强承载,西部地区次之,北部和东部地区承载力最弱;水资源承载力由强到弱依次为信阳、驻马店、南阳、郑州、三门峡、洛阳、平顶山、商丘、漯河、济源、许昌、周口、安阳、开封、鹤壁、新乡、焦作、濮阳;水资源子系统和经济子系统对城市水资源承载力影响较大,GDP、产水模数、降水量3个指标对河南省各地市2018年水资源承载力影响最大。

Taking 18 cities in Henan Province as the research objects,this paper selects 16 indicators from the water resources-society-economy-ecology composite system.Utilizing the entropy weight TOPSIS method,it conducts the spatial difference analysis and comprehensive evaluation of water resources carrying capacity on 18 cities in Henan Province in 2018.The evaluation results show that the water resources carrying capacity of Henan Province in 2018 is weak.From the perspective of spatial difference,the water resources carrying capacity is the strongest in the southern region,followed by the western region,and the northern and eastern regions are the weakest.Cities with descending water resources carrying capacity are as follows:Xinyang,Zhumadian,Nanyang,Zhengzhou,Sanmenxia,Luoyang,Pingdingshan,Shangqiu,Luohe,Jiyuan,Xuchang,Zhoukou,Anyang,Kaifeng,Hebi,Xinxiang,Jiaozuo,Puyang.The water resources subsystem and the economic subsystem have great influences on water resources carrying capacity in different cities.GDP,water production modulus,and precipitation affect the water resources carrying capacity most in 2018.
