长江三角洲城市带发展探讨

THE DEVELOPMENT OF CHANGJINAG DELTA MEGALOPOLIS

长江三角洲城市带已基本形成且正在扩展之中。其规模可与国外的五大城市带相比，但在城市化水平、交通通信网络结构和城市职能结构等方一面，存在着较大的差距，城市带的空间格局也在变化之中。未来的长江三角洲城市带，将以国际经济中心城市上海为中心城市，以南京、杭州、宁波为二级中心城市，以长江三角洲特大组合港和上海国际航空港为对外联系枢纽，以“Ｚ”字型复合发展轴为主体轴线，形成规模巨大、经济发达的世界特大城市带。

The Changjiang delta megalopolis has been formed and is expanding. Compared with other megalopolises of the world, this megalopolis has larger scale but the level of urbanization, the structure of transportation,communication network and the structure of urbanfunctions are less perect. Besides the spatial structure of the megalopolis is under change. Shanghai, the future world city will be the centre of the megalopolis, while Nanjing,Hangzhou, and Ningbo will be the subcentral cities. The superport at Changjiang delta and the Shanghai international airports will form the international connection junction, and the 'Z' shaped compound developing axis will be the surporting axis of the megalopolis.
