武汉城市圈社会经济—资源—环境耦合的演化分析

The Coupling Evolvement of ERE Composite System on Wuhan Metropolitan Area

都市圈社会经济—资源—环境的耦合协调机理已成为城市地理学研究的热点和前沿。建立都市圈社会经济—资源—环境耦合协调的演化度模型,基于时序数据分析了武汉城市圈社会经济—资源—环境耦合协调水平的演化特征:①1978—2009年社会经济发展水平不断提高,资源和环境水平震荡波动最终趋于平稳,资源环境系统对社会经济系统的响应和反馈较为明显,但有一定的时间滞后;②在规模分异上表现为由金字塔型结构向纺锤型结构演进的分异特征,在空间分异上表现为由核心边缘结构向等级圈层结构演进。

The issue on the coordinated development of social economy,resource and environment has been not only the core of regional development but also the key of current economic development.By taking Wuhan metropolitan area as a case,this study aims to construct the ERE dynamic coupling model and then analyzes the temporal evolvement of coupling degrees based on the method of Time Series Data Analyzing.The results show that： firstly,the social economy has increased gradually from 1978 to 2009,accompanied with the fluctuations of the resource and environment until even at last.The response and feedback of resources ＆ environment system to economic system has been evident,but lagged behind the economy development course;secondly,the dimensions difference characteristic presents the transformation from pyramid shape to spindle shape,and the spatial lamination evolves from center-marginal texture to rank circle level structure.
