| 摘 要： | 在中国经济社会发展和交通建设出现新转向的背景下,论文基于现状和相关规划完成后的陆路综合交通网络,解析了中国城市网络通达性的演化趋势及其对国土空间结构演进的影响,重点回应了“全国123出行交通圈”建设和国土开发均衡性2个问题。结果显示,已有规划的完成能够大幅提高中国城市网络的通达性水平,在最短旅行时间上基本可以支撑“全国123出行交通圈”的建设;通过促进轴—辐组织模式和空间级联秩序发育,已有规划能够引导国土开发结构朝多中心、网络化方向演进,为区域间的协调和均衡发展提供交通基础;未来应从支撑与引导、整合与衔接、效率与公平等方面持续优化交通服务的供给结构,提升综合交通运输体系服务人民生活和社会生产的能力。 |

| Abstract: | With the increasing emphasis on coordinated regional development, transport and socioeconomic developments in China have taken a new turn in recent years. Based on the present and future integrated land transport network, the trend of city network accessibility and its impact on the change of regional development patterns in China were analyzed in this study by focusing on the construction of travel circles and regional balance. The results show that the completion of the existing planning can greatly improve the accessibility of China's city network and can largely support the construction of travel circles according to the shortest travel time. By promoting the development of hub-spoke organization mode and spatial cascading order, the existing planning can guide the multi-center and networking development of spatial structure and provide a basis for the coordinated and balanced development between regions. In the future, China's transport development should continue to optimize the supply structure of transportation services and improve the ability of the integrated transport system to serve the needs of people's daily lives and production. |
