论高铁建设与城市结构调整背景下的中心型枢纽功能特征及空间对策

The Functional Characteristics and Spatial Measures of Central Hub,Under the Background of High-speed Railway Construction and the Reconstruction of Urban Spatial Structure

从高铁建设与城市发展带来的城市枢纽分工角度出发,将铁路客运枢纽分为综合型、中心型和独立型三种类型。从城市交通需求与空间结构变迁的趋势出发,将与历史文化名城关系密切的中心型枢纽的交通需求概括为对外交通职能弱化、公共交通职能强化以及枢纽换乘的升级和复杂化三个趋势。在厘清需求的基础之上,结合国内外先进案例,从空间的连续性与融合化、构筑以步行体验为线索的环境系列以及功能立体化与交通隐形化三个方面,详细介绍了适于这类枢纽的空间设计对策。

From the perspective of the function division of the urban transport hubs, which has been brought about by high- speed railway and urban development, this paper divides passenger hubs into three types： integrated hub, central hub and independent hub. Giving the change trends of urban space structure and the urban transportation needs, the traffic demand of the central hubs which are related strongly to the historical and cultural cities, can be summarized as follows： weakening of external transports; strengthen of public transports; and upgrade of transfer. Based on these demands, enlightened by the advanced cases domestic and abroad, the space solutions of central hubs are introduced in detail. These solutions include three major aspects： space continuing and integrating, pedestrian priority environment constructing, and using multiple spaces to achieve traffic stealth.
