黄河经济带生态文明建设与城市化耦合关系及空间特征研究

The coupling relationship and spatial characteristics analysis between ecological civilization construction and urbanization in the Yellow River Economic Belt

通过研究系统耦合协同评价体系,构建一个适宜大区域的评价生态文明建设和城市化情况的指标体系,借助该指标体系,从时空两个维度分析黄河经济带2008—2016年生态文明建设和城市化耦合协调发展状况、格局及空间关系。实证结果表明:(1)2008—2016年,黄河经济带生态文明建设成效并不显著,压力依然很大;城市化有所提升,但发展速度依然偏慢。两方面均不存在明显的龙头城市,且空间差异明显。(2)2008—2016年,研究区生态文明建设与城市化处于低度耦合阶段,协调度处于轻度失调状态,生态文明建设普遍滞后于城市化,表现出明显的空间异质性和行政指向性。(3)协调度表现出一定的空间依赖,存在一定的空间溢出效应,地理临近的区域更容易受高协调度区域的影响。

To explore the sustainability of regional development,on the basis of the system coupling collaborative evaluation system,a comprehensive index system suitable for large regions and multi-cities is constructed,which can evaluate the construction of ecological civilization and urbanization.With the help of this index system,the ecological civilization construction and the coupling and coordinated development of urbanization in 80 cities at and above the Yellow River Economic Belt from 2008 to 2016 were evaluated from two dimensions of time and space.Then,the exploratory spatial data analysis method is used to analyze the spatial pattern and spatial relation characteristics of the coupling coordination level in the research area.The empirical results show that:(1)From 2008 to 2016,the ecological civilization construction in the Yellow River Economic Belt did not achieve significant results,and the pressure was still very high,which proves the necessity and urgency of ecological protection and high-quality development in the Yellow River Basin.The overall urbanization had improved,but the entire development rate was still too slow.There was no obvious leading city in both aspects,and the spatial difference was distinct.(2)From 2008 to 2016,the ecological civilization construction and urbanization in the cities of the Yellow River Economic Belt were in a low degree of coupling,the coordination degree was slightly unbalanced,and the ecological civilization construction generally lagged behind the urbanization development.The spatial pattern was characterized by obvious spatial heterogeneity and administrative orientation.(3)The coordination degree of ecological civilization and urbanization in the research area showed a certain spatial dependence and spatial connection,and the coordination degree showed a certain spatial spillover effect,and the geographical adjacent areas were more susceptible to the influence of regions with high coordination degree.
