摘要： 轨道交通布局是优化城市与区域空间结构的重要推动力，也将加速城市空间更新。研究采用多源数据信息的内业解译与外业调研相结合的空间判定方案，基于城市空间的规模特征、职能属性、集聚模式等“三位一体”综合视阈下精细刻画轨道交通站域的城市空间演替轨迹与更新模式，研究发现：①城市中心区域型、高密度居住型、商服型站点的城市功能规模呈显著的缩减特征；②随着城市空间演替其职能属性主导化趋势显著，尤以高效益的餐饮娱乐、商务服务业态为主要功能构成；③轨道交通站域空间的城市功能呈集聚分布模式。鉴于此，面向SDG11的现实发展要求，提出我国轨道交通站域的城市空间更新应立足于回应可持续发展时代要求，兼顾经济效益与社会公平的站域空间规划；对标站域环境，构建“主导功能+混合用途”的空间可持续发展模式；精细考量功能集聚特征，激发轨道交通站域空间的持续发展活力等更新策略，以期为我国相继进入不同轨道交通发展阶段的站域空间更新及实现城市可持续发展提供重要启示和政策建议。 关键词： 轨道交通站域;  城市功能演替;  更新模式;  S')" href="#">SDGS     Abstract: At present, the layout of rail transportation is an important driving force for optimizing the spatial structure of cities and regions and will also accelerate urban space renewal. This paper uses inter-field interpretation of multi-source data information, combining the spatial judgment scheme, Based on the comprehensive perspective of “three-dimensional integration” scale characteristics, functional attributes and agglomeration patterns of urban functional space, finely depicted urban spatial succession trajectory and update model of the rail transportation station. The study found that: (1) urban space scale showed significant reduction in urban central area, high-density residential, commercial service site;(2) urban functional succession tends to dominate the update mode, especially the high-efficiency catering and entertainment, business service format is the main function;(3) urban function of the rail transit station space is agglomerated. Taking this as a reference, it is proposed that the urban spatial renewal of China's rail transit stations should be based on responding to the development requirements of the times and stimulating the spatial vibrancy of the station; corresponding to the station environment, rational allocation of functional elements; careful considerate functional agglomeration characteristics, optimize station space structure and update spatial succession framework strategy, in order to provide important inspiration and policy recommendations for China's successive access to the station space update and planning regulation of different rail transportation development stages.
