黄河中下游河南省高质量发展与生态环境耦合协调度时空格局研究

Spatial temporal pattern of coupling coordination degree between high quality development and ecological environment in Henan Province in the middle and lower reaches of the Yellow River

科学认知经济高质量发展与生态环境保护之间的耦合协调关系,对于指导我国未来可持续发展具有重要的现实意义.以地处黄河中下游的河南省为研究区域,构建经济高质量发展和生态环境评价指标体系,运用耦合协调度模型分析了两者之间的协调发展情况,结果表明:(1)河南省各市生态环境指数值域范围为0.143~0.808,北部和中部地区相对较低,南部和西南部相对较高,地域分异特征明显;(2)通过分析2014至2018年河南省各市高质量发展指数,发现郑州市历年均在0.8以上,远高于其他城市;(3)2014至2018年河南省各市耦合协调度值介于0.34~0.73,主要处于勉强耦合协调和中级耦合协调阶段,南北地区差异明显.针对河南省经济发展和生态环境保护现状,可通过构建中原城市群“一核一副四轴四区”的空间格局,引领其他城市经济快速发展,同时,通过建设黄河中下游生态走廊,加强黄河中下游生态环境同治共保.

Scientificly understanding of the coupling and coordination relationship between high-quality economic development and ecological environment protection is of great practical significance to guide China's future sustainable development.In this paper,Henan Province,which is located in the middle and lower reaches of the Yellow River,was taken as the research area to construct the evaluation index systems of high-quality development and ecological environment,and the development of coordination between them was analyzed by using the coupling coordination model.The results showed that:(1)the range of eco-environmental index in Henan Province was 0.143-0.808,the northern and central regions were relatively low,the south and the southwest were relatively high,and the regional differentiation was obvious;(2)By analyzing the high quality development index of Henan Province from 2014 tO_(2)018,it was found that Zhengzhou was above 0.8 over the years,far ahead of other cities;(3)From 2014 tO_(2)018,the coupling coordination degree of each city in Henan Province ranged from 0.34 to 0.73,mainly in the stage of barely coupling coordination and intermediate coupling coordination,with obvious differences between the north and the south.In view of the current situation of economic development and ecological environment protection in Henan Province,the rapid economic development of other cities can be led by constructing the spatial pattern of"one core,one vice,four axes and four districts"in the Central Plains Urban Agglomeration.At the same time,the ecological environment should be jointly managed and protected by constructing the ecological corridor in the middle and lower reaches of the Yellow River.
