摘要
粤港澳大湾区城市群作为世界四大湾区城市群之一,在国家发展格局中占有重要的地位。基于多源数据,利用重心迁移模型、扩张演化模型及改进的引力模型探究近20年粤港澳大湾区城市群的演化。结果表明:①在城市演化类型上,澳门、肇庆呈单向型演化,佛山、中山、珠海、惠州、香港呈双向型演化,广州、江门、东莞、深圳呈发散型演化;2008~2017年城市群整体的扩张速度与强度低于1998~2008年。②近20年粤港澳大湾区城市群的城市质量、关联度呈不断上升趋势,并表现出一定的区域性和不平衡性,城市质量与经济发展程度、城市空间呈正相关关系,城市质量高的城市与周边城市的关联度高;③粤港澳大湾区城市群的社会经济区位度存在明显"断层",缺乏合理的梯度等级,并表现出一定的空间分异且部分城市的区位度演化显著。
Guangdong-HongKong-Macao Greater Bay Area urban agglomeration plays an important role in the national development pattern.Based on the multi-source data,the evolution is studied by using the center of gravity model and the improved gravitional model.The results show that:(1)In the type of urban evolution,Macao and Zhaoqing is unidirectional evolution,Foshan,Zhongshan,Zhuhai,Huizhou,Hong Kong is two-way evolution,Guangzhou,Jiangmen,Dongguan,Shenzhen have divergent evolution,and urban agglomeration from 2008 to 2017 The overall expansion speed and intensity of the group is lower than that of 1998-2008.(2)In the past 20 years,the urban quality and correlation degree of Guangdong-Hong Kong-Macao Greater Bay Area urban agglomeration are on the rise,and show a certain regional and imbalanced,the degree of economic development,the urban space and urban quality have a positive correlation,and the city with high urban quality has a high correlation with the surrounding cities;(3)There are obvious"faults"in the social-economic Location of Guangdong-Hong Kong-Macao Greater Bay Area urban agglomeration,lack of reasonable gradient grade,and show certain spatial differentiation and significant evolution of location degree in some cities.
