多维视角下黄河流域水环境与社会经济协调性研究

Research on the Water Environment⁃Social Economic Coordination of the Yellow River Basin from a Multi⁃Dimensional Perspective

从多个逻辑维度和空间视角研究了黄河流域水环境与社会经济的协调度。在流域水环境与社会经济交互作用分析的基础上,从水资源、水污染及水治理3个逻辑维度构建黄河流域水环境指标体系,采用耦合协调模型,衡量黄河流域水环境与社会经济的整体协调度;从黄河流域上中下游、七大沿黄城市群及61个城市3个空间视角和水资源、水污染及水治理3个逻辑维度,采用邓氏关联度方法测度水环境与社会经济的关联水平并探究其成因。结果表明:黄河流域水环境与社会经济间整体协调度较低但呈上升趋势;2009—2018年,3个逻辑维度下水环境与社会经济的关联度均为0.7~0.8,空间分异性不明显;2009—2018年,黄河流域中游水环境与社会经济的关联度有所上升,流域上游和下游的关联度有所下降,太原城市群的关联度呈上升趋势,宁夏沿黄城市群的关联度稍有下降;61个城市中,需重点关注陇南市、临汾市、宝鸡市等水资源与社会经济之间关联度高的城市,固原市、陇南市、晋城市等水污染与社会经济之间关联度高的城市,临汾市、庆阳市、巴彦淖尔市等水治理与社会经济之间关联度低的城市。

This paper studied the coordination degree between water environment and social economy in the Yellow River basin from multiple logical and spatial dimensions.Based on the analysis of the interaction between water environment and social economy,the water environment index system of the Yellow River basin was constructed from three logical dimensions of water resources,water pollution and water govern⁃ance.The coupling coordination model was used to measure the overall coordination degree between water environment and social economy in the Yellow River basin.From the three spatial dimensions of the upper,middle and lower reaches of the Yellow River basin,seven urban ag⁃glomerations along the Yellow River and 61 cities,and three logical dimensions of water resources,water pollution and water governance,this paper used Deng’s correlation degree method to measure the correlation level between water environment and social economy and explore its causes.The results show that the overall coordination degree between water environment and social economy in the Yellow River basin is low but increasing.From 2009 to 2018,the correlation degree between the three logical dimensions of water environment and social economy fluctuated between 0.7-0.8 and the spatial differentiation is not obvious.From 2009 to 2018,the correlation degree between water environ⁃ment and social economy in the middle of the Yellow River basin has been increased,while the correlation degree between water environment and social economy in the upper and lower reaches of the Yellow River basin has been decreased.Taiyuan urban agglomeration shows an in⁃creasing trend and Ningxia urban agglomeration along the Yellow River decreases slightly.Among the 61 cities,it needs to focus on the cities of Longnan,Linfen and Baoji that have high correlation between water resources and social economy,the cities of Guyuan,Jincheng and Longnan that have high correlation between water pollution and social economy and the cities of Linfen,Qingyang and Bayannur that have low correlation between water management and social economy.
