交通系统对港城空间拓展的影响要素

港口活动和城市活动既可以相互促进也可以相互制约,陆域交通系统同时承载这两种活动,对港城的发展至关重要。基于国内外港城发展实例,对港城空间拓展模式进行研究,发现交通系统制约的问题在港城规模上升阶段普遍存在,得出关键影响要素:1)港城交通体系需求层次与交通分流系统的匹配; 2)交通系统与港城用地布局的协调; 3)港口规模与港城集疏运道路系统的匹配。本文结合案例进行定性和定量分析。

Influential factors of traffic system on port-city expansion

Port activities and urban activities can both promote each other and restrict each other.The land transportation system carrying both activities is crucial to the development of the port city. Based on the development examples of domestic and international port-cities,and studying the spatial expansion mode of the port-city,we find that the problem of transportation system constraints is widespread in the rising stage of the port-city,and the key influential factors are obtained as follows:1)the matching between the traffic demand hierarchy and the traffic diversion of the transport system;2)the coordination of traffic system and land use layout;3)the matching between the port size and the number of transport channels.Combining with the case analysis,we carry out qualitative and quantitative analyses.
