摘要:

以黄河流域35个城市为研究对象,分别构建产业绿色化与生态环境绿色化指标体系,基于熵值法测度两系统综合指数,并通过耦合协调度模型和空间自相关法对2009—2018年两系统耦合协调度的时空特征及空间集聚性进行分析。结果表明:(1)黄河流域产业绿色化与生态环境绿色化综合指数总体呈上升趋势且具有趋同性,上游地区生态环境绿色化水平高于产业绿色化水平,中下游地区相反;(2)时空维度上,黄河流域产业绿色化与生态环境绿色化的耦合协调度总体呈上升趋势,上中下游地区呈现“凹”字型发展特征且稳定程度不同;(3)空间集聚上,黄河流域产业绿色化与生态环境绿色化耦合协调度呈显著正相关性,存在明显聚集性,高-高聚集主要集中于上游地区,低-低聚集由中游地区向中下游地区扩展。

Abstract:

Taking 35 cities in the Yellow River Basin as the research object, the index systems of industrial greening and ecological environment greening are constructed respectively. Entropy weight method is used to calculate the comprehensive indexes of the two systems. Furthermore, based on the coupling coordination degree model and spatial autocorrelation method, the spatio-temporal characteristics and spatial agglomeration of the coupling coordination degree of the two systems are analyzed from 2009 to 2018. The results show that: (1) In terms of comprehensive level, the comprehensive indexes of industrial greening and ecological environment greening in the upper, middle and lower reaches of the Yellow River Basin show an upward trend and are generally similar. The greening level of eco-environment is higher than that of industry in the upper reaches, but it is lower than the greening level of industry in the middle and lower reaches. (2) In terms of spatiotemporal dimension, there is an upward trend in the coupling coordination degree of the industrial greening and ecological environment greening in the Yellow River Basin. The upper, middle and lower reaches in the Yellow River Basin are characterized by "high-low-high" development, and their development stability is different. (3) In terms of spatial agglomeration, there is a significant positive correlation between industrial greening and ecological environment greening in the Yellow River Basin, indicating that there is obvious aggregation in space. High-high aggregation is mainly concentrated in the upper reaches, and low-low aggregation extends from the middle reaches to the middle and lower reaches.

Key words: Yellow River Basin, industrial greening, ecological environment greening, coupling coordination degree
