长江三角洲全球城市区空间建构

在全球化背景下，全球城市区作为一种新的城市空间和功能组织形式，通过全球城市接入全球经济网络，在全球城市体系中发挥着越来越重要的作用。通过分析长江三角洲地区不断深入的全球化进程和不断加强的城镇一体化态势，提出长江三角洲地区是中国最有可能建设成为全球城市区的区域；进而从全球城市区的空间建构和功能组织的角度，提出通过提升上海全球城市功能，打造南京、杭州、苏州、宁波的次级全球城市职能，强化城市间的功能联系，构筑区域网络一体化支撑体系，构建“多中心层域式、网络状一体化”的长江三角洲全球城市区；并提出面向全球化和基于地方化的区域功能组织结构，打造若干全球化战略区以推进长江三角洲全球城市区建设。

SPATIAL STRUCTURE CONSTRUCTION OF GLOBAL CITY-REGION IN THE YANGTZE RIVER DELTA

In the context of globalization,as a new kind of urban spatial and functional form,global city regions are submerged into the global economic network through global and sub-global cities,and are showing increasingly important functions in the global city system.Through the analysis of the globalization process of the Yangtze River Delta and incorporation of cities and towns in this area,the authors point out that this region is the most probable region to become the global city region in China.Then,from the angle of reorganizing and upgrading the spatial and functional structure of the global city region,it is proposed that Shanghai should enhance its function as a global city;Nanjing,Hangzhou,Suzhou and Ningbo should function as sub-global cities;the interrelations among cities should be strengthened;and the regional supporting network of traffic,communication and market etc should be constructed.Thus,the polycentric,network integrative global city region can be established.In addition,the paper suggests several strategic districts to promote the construction of the global city region in the Yangtze River Delta.
