湾区城市群空间关系及跨海通道影响机制研究

在海洋经济日益成为世界经济主流的背景下,湾区城市群往往成为一国城镇化发展的空间头部区域,对一国参与全球竞争的格局态势产生重要影响。本研究在对近代城市群空间关系理论进行梳理的基础上,运用复杂网络分析方法,对纽约湾区、旧金山湾区、东京湾区、粤港澳湾区城市群空间关系展开实证研究。从网络整体、节点城市两个层面,对湾区城市群空间关系进行综合研判,并对跨海通道的空间关系影响进行量化分析。研究发现,四大湾区在整体格局、节点城市空间关系权重上存在较大差异;同时,各大湾区跨海通道的建设对城市群空间关系改变显著,其影响模式与程度并不与设施距离构成简单线性关系,而是与湾区陆海空间架构、节点城市与设施的空间分布方式、路网格局等要素存在复杂关联。本研究提出的湾区城市群空间关系测度方法体系,有助于深入理解湾区城市群空间关系特征及演变规律,对于湾区城市群空间发展策略的制定和优化,具备科学参考价值。

Spatial Relationship of Urban Agglomerations in Bay Area and the Influence Mechanism of Cross-sea Channels

With marine economy increasingly becoming the mainstream of the world economy,the urban agglomeration of the Bay Area develops to be a spatial head region for the development of a country’s urbanization.Based on the spatial relationship theory of modern urban agglomerations,this study used complex network analysis methods to conduct empirical researches on the spatial relationship between the New York Bay Area,San Francisco Bay Area,Tokyo Bay Area,and the Guangdong-Hong Kong-Macao Greater Bay Area.This study established an evaluation index system,comprehensively studied the spatial relationship of urban agglomerations from the two perspectives of the whole network and node cities,and quantified the spatial relationship of important cross-sea channels.The study found that there is a great difference in the overall pattern and the weight of the spatial relationship between the four Bay Areas.Besides,the construction of the cross-sea channels in the Bay Areas would change the spatial relationship of urban agglomerations significantly.There is a complex relationship with the land-sea space framework of the Bay Area,the spatial distribution of node cities and facilities,and the road grid patterns.The research method of spatial relationship of the Bay Area urban agglomeration proposed in this study is helpful to understand the spatial relationship characteristics and evolution law of the urban agglomeration in the Bay Area and would have scientific reference value for the Bay Area to formulate and optimize spatial development strategies.
