城市轨道交通与城市空间形态模式选择

从土地使用功能、开发强度、沿线土地价值、城市用地布局及地区经济活力5个方面阐述了轨道交通对土地利用的影响。分析了轨道交通对城市空间形态的影响，包括引导城市空间结构调整、促进城市发展轴形成、带动城市中心区和副中心区发展3个方面。探讨了基于轨道交通的城市空间形态发展模式，主要有轴向、组团式、主轴-网络状3种。最后，指出大城市空间形态模式的选择应充分考虑轨道交通的特征，借鉴主轴-网络状模式。

Development Patterns of Urban Rail Transit and Spatial Structure

The paper elaborates the impacts of rail transit on urban land use from various angles, such as land-use functions, intensity of development, land value along rail lines, urban land-use arrangement, economic development vitality, etc.. Then the paper analyzes the impacts of rail transit on urban spatial structure in terms of guiding the adjustment of spatial structure, facilitating the formation of urban development axis, as well as promoting the development of urban central and sub-central districts. Given the above analyses, the paper explores three urban spatial development patterns based on rail transit, namely, axis, group, and a major axis plus separate networks. Finally, the paper points out that the selection of spatial development patterns in large cities should fully consider rail transit characteristics, with a leaning towards the last pattem.
