黄河流域生态保护与高质量发展耦合协调性及障碍度研究

Study on the Coupled Coordination and Barrier Degree of Ecological Protection and High⁃Quality Development in the Yellow River Basin

为给黄河流域生态保护和高质量发展的政策研究提供参考,以2006—2020年黄河流域九省(区)为研究对象,分别构建生态保护与高质量发展评价指标体系,采用熵值法进行测度,并借助耦合协调模型和障碍度模型,探究生态保护与高质量发展2个系统之间的耦合协调关系及其障碍因子。结果表明:1)黄河流域九省(区)生态保护与高质量发展时序上发展态势良好,但各省(区)异质性明显;2)黄河流域生态保护与高质量发展耦合协调度整体处于上升阶段,但水平仍较低,在时序上经历了濒临失调—勉强协调—基本协调的演变历程,在空间上呈现下游>中游>上游的分布格局;3)黄河流域生态保护与高质量发展耦合协调关系主要受污染治理、生态建设和创新发展三重制约,且各省(区)的主要障碍因子存在差异。

In order to provide reference for the policy research of ecological protection and high⁃quality development in the Yellow River Ba⁃sin,taking 9 provinces in the Yellow River Basin from 2006 to 2020 as the research object,the evaluation index system of ecological protec⁃tion and high⁃quality development was built respectively.It measured by entropy method and explored the coupling coordination relationship and obstacle factors between the two systems with the help of coupling coordination model and obstacle degree model.The results are show that a)the overall trend of ecological protection and high⁃quality development in the Yellow River Basin is good,but the heterogeneity of each province is obvious.b)The coupling and coordination degree of ecological protection and high⁃quality development in the Yellow River Basin is on the rise as a whole,but the level is still lower.In terms of time sequence,it has experienced the evolution process of near imbal⁃ance⁃barely coordination⁃basic coordination,and the spatial distribution pattern is downstream>midstream>upstream.c)The coupled and coordinated relationship between ecological protection and high⁃quality development in the Yellow River Basin is mainly constrained by the triple constraints of pollution control,ecological construction and innovative development,and there are differences in the main obstacle fac⁃tors in each province(region).
