交通枢纽的空间演进与发展机理

长时间序列的交通枢纽空间分布格局的演进规律，一直是国内外交通地理学有待解决的问题。考察交通枢纽的长期演变规律，有助于把握交通枢纽的发展机理，为空间优化提供科学支撑。对秦汉时期以来中国交通枢纽分布格局的发展过程与空间特征进行系统解析，认为存在秦汉至南北朝、隋唐、宋朝至辽金时期、元明、清朝、民国至今等6个阶段。基于中国不同历史阶段交通枢纽的发展轨迹，总结了交通枢纽的基本形成条件和空间演变的一般过程，并对交通枢纽的生命周期进行了分析，在此基础上，深入研究了交通枢纽的基本发展模式，系统总结了中国交通枢纽空间布局的基本形态。相关研究既是对交通枢纽研究的理论完善，也是中国交通枢纽布局规划的理论基础。

Research on Spatial Evolution and Development Mechanism of Transport Hubs

The evolution of spatial pattern of transport hubs has been a concern for the transportation geography at home and abroad over a long period of time.Studying the long-term evolution of transport hubs can help grasp the development mechanism of transport hubs,and provide a scientific basis for space optimization.Through a systematic analysis of the development process and spatial patterns of transport hubs since the Qin and Han dynasties in China,it is indicated that there were six stages of space evolution of transport hubs:(1) from the Qin and Han dynasties to the Southern and Northern Dynasties;(2) from the Sui Dynasty to the Tang Dynasty;(3) from the Song Dynasty to the Liao and Jin dynasties;(4) from the Yuan Dynasty to the Ming Dynasty;(5) The Qing Dynasty;(6) from the Republic of China till now.Based on the development path of transport hubs of China in different historical stages,this paper summarized the conditions of transport hubs formation and the general process of spatial evolution,and analyzed the life cycle of transport hubs.On this basis,this paper studied the basic development model of transport hubs,and summarized the spatial layout of transport hubs in China.
