地铁引导下武汉市城市空间形态的演变

The Evolution of Wuhan Urban Morphology with the Leading of Metro

地铁已经逐渐成为中国大城市主导的公共交通方式,地铁的发展将会对城市的空间形态产生巨大的影响。以武汉地铁为研究对象,从城市内部空间结构和外部建设用地两方面具体分析武汉地铁对城市空间形态产生的影响。分析得出,在地铁引导下,武汉市主城区内部各类型功能空间发生多样交互,城市空间结构从相对独立向多核网络式形态发展;随着地铁从主城区向外部新城延伸,主城区外部的建设用地以地铁线为轴线呈放射式向外拓展,新城组团以地铁站为核心呈卫星状分布于主城区周围。武汉市应以地铁建设为先导,构建以地铁为核心的公共交通网络,引导城市内部功能优化布局和城市外部空间集约拓展。

The metro has become the dominant public transportation in large cities gradually, the development of the metro will have a significant impact on urban space form. Taking Wuhan metro as the object of research, we analyze the impact of Wuhan metro to urban spatial from the urban internal spatial structure and external construction land. Through analysis, with the leading of metro, each type function space has started to interact in Wuhan main urban area, urban spatial structure has been changed from the relative independent form to multi-core network form. With metro extend from the main urban area to the external new towns, the external construction land takes metro line as axis to expand outward, the new towns group take metro station as the core to distribute around the main urban area like satellites. Wuhan should take metro as the core to build public transport network, which can guide the optimized layout of the urban internal functions space and urban external space develop intensively.
