泛长三角地区经济发展-空间开发-环境演变耦合协调的时空格局演化

Spatio-temporal Pattern Evolution of Economy Development-Space Exploitation-Environment Evolution Coupling Coordination in the Pan Yangtze River Delta

运用耦合协调模型测算2005、2010、2016年泛长三角地区经济发展-空间开发-环境演变的耦合协调度及两两系统间的耦合协调度并分析其时空格局演化特征。结果表明:(1)经济发展-空间开发-环境演变耦合度的时空格局差异明显,空间上呈"东北高、西南低"的格局特征,时间上呈接近于"S"型的演变态势;(2)经济发展-空间开发-环境演变的耦合协调度与其耦合度的空间格局具有一定关联性,整体上呈较为显著的"中东高、南北低"的空间分布特征,时间上其演变态势接近于倒"U"型的成长曲线;(3)经济发展-空间开发-环境演变两两系统间耦合协调状况差异明显,"经济发展-空间开发"的耦合协调情况相对较差,是未来亟待加强和优化的重点方向;而"经济发展-环境演变"整体上处于较高的耦合协调状态;"空间开发-环境演变"耦合协调的上升幅度较快。

This article aims to reveal the coupling coordination degree among economic development,spatial development and environmental evolution,and the coupling coordination degree between any two systems in the Pan-Yangtze River Delta region in 2005,2010 and 2016.In this paper,the index system have been built embodying these three aspects,based on the coupling coordination model,the spatial-temporal pattern and the rule of coupling co-evolution of coordination degree of economic development,spatial development and environmental evolution,and the coupling coordination degree between any two systems were examined comprehensively.Main results for this study are as follows:1、The coupling degree of economy development,space exploitation and environment evolution exhibited significant difference spatially and temporally;to be specific,it presented a spatial pattern of“high in the northeast and low in the southwest”.In the time dimension,it is in an evolutionary trend close to the“S”type.2、The coupling coordinating degree of economy development,space exploitation and environment evolution has a certain correlation with the spatial distribution of its coupling degree,it presented a spatial pattern of“high in the middle and east,and low in the south and north”.In the time dimension,it is in an evolutionary trend close to the growth curve of the inverted“U”type.3、There were obvious differences of coupling coordination status between any two systems,the coupling coordination of economy development and space exploitation had the poorest condition.Thus,it is the key direction to be strengthened and optimized in the future;whilst the coupling coordination between economy development and environment evolution had high coupling coordination condition;and the coupling coordination of space exploitation and environment evolution had increased faster.
