特大城市依托快速交通有机疏散路径研究

我国特大城市承载力的动态平衡不仅关系到城市自身的可持续发展，更关系到城镇体系和城市一区域系统的整合优化。由于现阶段我国特大城市的集聚效应远高于扩散和辐射效应，导致特大城市地域空间上的资源要素供给与需求矛盾突出。随着快速交通的发展，加快特大城市人口、产业以及功能在内部地域空间、城镇体系和城市一区域系统三个层面的有机疏散，更加突出作为国家区域性中心城市的主要职能，从而实现特大城市资源要素供给与需求的平衡。

Study on Organic Decentralization in Megalopolis during Development of Rapid Transit

At present, with the rapid development of the urbanization in China and the increasing reinforcement of the centralization function of the megalopolis, the conflict between the rapid growth of the population and the bearing capacity of the resource environment is becoming serious day by day. The acceleration of the organic decentralization in the megalopolis is proposed gradually in recent years, but the situation that the population and industry are excessively centralized in the regional space in the megalopolis is not changed radically, and the urban development pattern of frying cake is still not suppressed effectively. In the event that the rapid transit technology becomes mature, the organic decentralization of the population, industry and function in the megalopolis by means of the rapid transit will promote the dynamic balance between the supply and demand of the essential resources in the megalopolis effectively, so as to achieve the enhancement of the bearing capacity.
