交通模式对城市空间形态影响的实证分析--以南京都市圈城市为例

该文以南京都市圈城市为例，通过纵向和横向比较，提出了南京都市圈中城市在水运时期的单侧带状和散点状布局、陆路时期的星状或块状布局以及综合高速交通时期的都市连绵带三种空间布局形式，并分析了交通模式对城市空间布局的作用机制，即交通产业的自身推动力、产业连锁循环动力、辐射集聚动力以及环境动力。笔者认为，今后交通模式仍将是影响城市形态发展变化的重要因素，继续通过其各种关联效应形成城市的发展轴线。对南京都市圈而言，强化其内外交通，扩大其集聚和辐射的腹地范围是健康发展的先行因素。

Analysis on the Relationship between Transportation Pattern and Urban Spatial Shape--A Case Study of Naniing Urban Agglomerations

Transportation is the never-dry power of urban development.It also has a significant impact on city spatial expanding.There are different transportation patterns in different historic period and different location,and they determine the patterns of city spatial shape.This paper,taking Nanjing agglomerations as an example,puts forward three patterns of urban spatial shape by historical and transverse comparison:one-side brand-shape or dot-shape in water-carriage period,star-shape or block-shape in land-way period,urban agglomerations belt in high-speed traffic period,and makes an analysis of the mechanism of transportation on city,including traffic industry interlink power,radiation and centralization power,environmental power.The conclusion is that the transportation pattern will still be an important factor for city spatial shape in the future,and it will become the axes of city development.The traffic structure and hinterland are the premise for the development of Nanjing agglomerations.
