青海省水资源-环境-社会经济系统耦合协调特征

Coupling and Coordination Characteristics of Water Resources⁃Environment⁃Socio⁃Economic System in Qinghai Province

水资源、环境、社会经济系统之间相互影响、协同演进,对3个系统相互作用关系的研究是目前的热点。为探究水资源-环境-社会经济系统的耦合协调特征,以青海省为研究对象,构建多系统评价指标体系,利用耦合协调模型及灰色关联模型对2000—2020年青海省水资源-环境-社会经济系统耦合协调特征进行定量评价。结果表明:(1)研究期内,青海省水资源、环境、社会经济子系统的评价指数呈现不同程度的增大趋势;(2)水资源-环境-社会经济系统耦合度处于融合高水平阶段,耦合协调度处于由中级协调向良好协调过渡的阶段;(3)在3个子系统中,水资源子系统的发展水平对青海省水资源-环境-社会经济系统耦合协调发展影响较大,环境子系统次之,社会经济子系统的影响相对较小。

Water resources,environment and socio⁃economic systems interact with each other and evolve cooperatively.Research on the in⁃teraction among the three systems is a hot topic at present.In order to explore the coupling and coordination characteristics of water resources⁃environment⁃socio⁃economic system,this paper took Qinghai Province as the research object and constructed a comprehensive evaluation in⁃dex system.Based on the statistical data of water resources,environment and socio⁃economic systems in Qinghai Province from 2000 to 2020,it used coupling coordination model and grey correlation model to quantitatively evaluate the coupling and coordination characteristics.The results show that a)during the study period,the evaluation indexes of water resources,environment and socio⁃economic systems in Qinghai show an upward trend of varying degrees.b)Coupling degree of water resources⁃environment⁃socio⁃economic system is at a high level of inte⁃gration,and coupling coordination degree is in a transitional stage from intermediate to good coordination.c)Among the three subsystems,the development level of the water resources system has stronger influence to the coupling and coordinated development of Qinghai Province,the environment system is the second one and the socio⁃economic system has relatively weaker influence.
