摘　　要：运用定量分析方法动态识别三大典型城市群空间范围,探讨中国城市群空间扩展的驱动机制,建立城市群空间演化的一般过程模型。研究发现:2010年,长三角城市群不仅扩展到苏北和浙南地区,而且沿长江扩展到安徽的沿江区县,江淮城市群已经成为长三角城市群的组成部分,区域性、网络化的城市群正在形成;在行政分割的制约下,成渝城市群实际上是由相互分割的成都城市群和重庆都市区组成;武汉城市群受到更多的政策性引导,正以武汉、宜昌、襄阳为支点形成初具规模的城市群。尽管经济力量是城市群空间扩展的核心驱动力,但制度因素、自然条件等对于中国城市群空间扩展的影响同样极其重要,在城市群发育的不同阶段,城市群空间扩展的主要影响因子也在发生变化。基于城市群空间扩展模式建立了城市群空间演化过程的五阶段模型。Based on quantitative analysis on dynamically identifying spatial extent of three representative urban agglomerations,this paper discusses the driving forces of urban agglomerations＇ spatial expansion in China and establishes a process model based on urban agglomerations＇ spatial evolution. The results show that Yangtze River Delta Urban Agglomeration has not only extended to the north of Jiangsu province and the south of Zhejiang province,but also to Anhui province along the Yangtze River. Jianghuai Urban has become an integral part of the Yangtze River Delta Urban,which is becoming regional and networking. Because of the constraints of administrative division,Chengdu-Chongqing Urban is actually divided by Chengdu Urban and Chongqing metropolitan area. Influenced by policy guidance,Wuhan Urban is developing bigger with the fulcrum of Wuhan,Yichang and Xiangyang. Although economic power is the core driving force of urban agglomerations＇ spatial expansion,the influence of institutional factors and natural conditions is equally vital. During different stages of urban agglomerations＇ development,main factors of spatial expansion are different. Finally,this paper establishes a spatial evolution process model based on urban agglomerations＇ spatial expansion.
