The Coupling Evolvement of ERE Composite System on Wuhan Metropolitan Area
以武汉城市圈为例，构建ERE动态耦合模型，分析1978-2009年社会经济、资源与环境的耦合度时间演化，发现经济持续增长而资源环境波动，且空间结构从金字塔形向纺锤形转变。
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.
