摘要
城市快速轨道交通是一种快速、便捷、大容量的公共交通系统,它不仅有效地缓解了城市的交通压力,同时城市轨道交通的规模和线路走向也同城市的空间结构发展密切相关。本文在对原有城市引力模型加以修正的基础上引入城市引力场概念,建立了城市轨道交通条件下以交通时间为基础的城市引力场模型,并对参数的影响因素和变化趋势进行了讨论。最后以上海为实例,按建设城市轨道交通的时间顺序绘制了不同时期城市引力场分布图,揭示了城市轨道交通建设与上海发展的密切关系,指出规划中的上海城市轨道交通网对形成“多中心”的城市空间结构具有积极的促进作用。
Urban rail transit is a high-capacity rapid convenient public traffic system. It can meet the needs of urban transportation, also guide the development of city. In this paper, the gravitation field model based on traffic time is built, which comes from the gravitation model amended, and the parameters have also been discussed. A series of gravitation field distributing chart according to shanghai shows that the gravitation field has been strengthened along the line of urban rail transit and these areas＇ development is largely influenced by the urban rail transit. Finally, the paper points that the urban rail transit system which has been planned will help to form multi-center urban space layout in Shanghai.
