摘要: 广州市在2000 年提出“东进、西联、南拓、北优”的城市空间发展战略,2010 年初步形成“两心四城”城市空间格局,随后在发展战略中加入“中调”,以进一步优化城市发展布局,谋求在2020 年形成多中心、组团式、网络型的城市空间架构。城市空间发展战略调整有赖于城市交通基础设施建设的支撑,同时交通基础设施的完备程度与密度也是进行城市通达性差异研究的重要基础。近年来,广州的城市交通通达性发生了深刻变化,对城市空间结构布局产生了深远影响。在此背景下,借助地理信息系统,运用网格分区法对广州市交通基础设施进行区域划分和密度计算;进一步结合快速轨道交通(地铁)网络的时间通达性度量,对广州市的城区通达性进行综合评价,并分析其空间特征。研究结果表明,广州市城区的通达性呈现同心环状的空间分布格局,区域差异性较大,城市空间布局有待进一步完善和优化。在此基础上,基于地铁网络时间通达性和区域交通基础设施密度值进行区位等级划分,探讨区位因素与交通通达性的相互关系;并结合城市公共、商业服务设施和住宅区的空间特征差异,进一步甄别广州城市通达性空间格局特征和区域差异,从而为城市建设和空间发展提供科学参考。

Abstract: The city of Guangzhou has proposed an urban spatial development strategy characterized by "advancing to the east, connecting with the west, expanding to the south, and optimizing in the north" in 2000. The initial target of this strategy was to form an urban spatial pattern of "two centers and four towns" in the city of Guangzhou by 2010. Later "adjusting in the central area" was added to the strategy to further optimize the layout of urban development, and to form a multi-center, clustering, and network type of urban spatial architecture by 2020.The implementation of this urban spatial development objective and the strategic adjustment require the essential support provided by the urban transport system, which demands higher quality development of the system. Urban transport infrastructure construction and the layout not only reflect the level of development of the city, but also are the important indicator and object of study and investigation of the differences in urban accessibility. With the development of urban transport in Guangzhou, especially the urban rail rapid transit (metro) network development in recent years, urban transport accessibility of the city has undergone significant changes, and also has an essential impact on and plays a key role in the structure and layout of urban spatial extension. In this context, this paper applies a grid-based partition method in a GIS (Geography Information System) environment to calculate the transportation infrastructure densities (including road density and bus line density) and analyze their spatial distribution. Moreover, this study measures the urban rail rapid transit network time-based accessibility based on matrix analysis and comprehensively investigates urban accessibility and its spatial characteristics in Guangzhou. The results show that the spatial pattern of urban accessibility in the city of Guangzhou is characterized by a concentric ring structure radiating outwards from the core area of the city. There are large regional variations between different areas in urban accessibility and the urban spatial pattern and structure of the city should be further improved and optimized. On the basis of multiple indicators, including time-based accessibility indices at each metro station and regional urban transport infrastructure densities, the study area is divided into different zones and the relationship between location and transportation accessibility is explored. At last, this paper integrates the spatial distributions and differences of urban public, commercial and residential facilities to further examine the characteristics and differentiation of urban spatial pattern in the city of Guangzhou, in order to provide scientific supports for the urban construction and spatial development.
