摘要
1990年代以来,中国步入快速城市化阶段,其中京津冀、长江三角洲和珠江三角洲三大城市群成为引领我国城市化发展的主导力量。本研究耦合城市异速增长和标准化区位商分析方法,对三大城市群1990年代至今的城市化动态特征进行对比研究,探讨城市形态扩张与功能演变的耦合作用过程。结果显示:①在城市形态扩张方面,三大城市群异速增长类型差异显著,其中长江三角洲和珠江三角洲分别呈现持续的负异速增长和正异速增长形式,分别表现为人口高度聚集和建成区急剧扩张特征;而京津冀呈现正负异速增长交替增长形式,人口集聚与建成区扩张程度均较低;②在城市功能演变方面,三大城市群第二产业发展阶段不同,第三产业格局演变差异明显;③城市形态与功能耦合作用促成了城市群城市化进程向不同方向发展;对外开放、技术创新、政府干预等是影响城市群形态扩张和功能演变的主要驱动力。鉴于三大城市群对我国城市化发展的主导作用,对其形态扩张与功能演变动态特征的对比研究能够深入理解国家及区域尺度的城市化发展规律和机制,并对我国其他城市群的科学、持续发展提供理论和实践指导。
Since the 1990s, China has already entered a rapidly developing stage of urbanization and Jingjinji, Yangtze River Delta and Pearl River Delta urban agglomerations have become the leading force. This paper firstly analysed the urbanization dynamic characteristics of the three major urban agglomerations from dynamic features of ubran allometric growth, industry pattern evolution and city function readjustment, based on the methods of urban allometric growth analysis and standardized location quotient. Then, the interaction between city spatial expansion and function evolution was also discussed. The results indicated that： （ 1 ） there were significant differences among the three urban agglomerations about urban growth ways and ubanization level; （2） the secondary and tertiary industries spatial distribution patterns of the three major urban agglomerations differed significantly; （ 3 ） the differences of internal coupling process between urban expansion and function evolution reflected different development levels among the three urban agglomerations, and vice versa. In view of their leading roles in China＇ s urbanization, the comparative analysis of their urbanization dynamic characteristics can make contributions to the in-depth study about the city development pattern and mechanism on the national and regional scales and provide theoretical and practical guidance for the development of other urban agglomerations.
