轨道站点是轨道交通系统与城市空间直接联系的重要节点，能够引导居住人 口、岗位在轨道站周边区域 ( 简称站域) 集聚以支撑城市空间结构优化。本研究结合 上海数据分析距离市中心不同圈层轨道站域居住人口和就业岗位集聚水平，讨论就业型 和居住型 2 大类 8 小类轨道站域职住密度分级与空间区位对应关系。对照 “上海市城市 总体规划 ( 2016—2035) ”中的城市主中心 － 城市副中心 － 地区中心体系规划，采用中 心支持度指标，同时考虑轨道站与城市中心体系的空间耦合关系和站域集聚的综合密 度，得出就业岗位和居住人口向郊区轨道站集聚还处于起步阶段; 服务各级中心的轨道 站综合密度 均 值 由 大 到 小 为: 4. 3 万/km2 ( 城 市 主 中 心) 、1. 5 万/km2 ( 副 中 心) 、 1. 3 万/km2 ( 地区中心) 。识别出在后续城市更新中需要引起关注的中心支持度较低/低 的城市副中心和地区中心 38 个。本研究将为郊区城市副中心、地区中心的轨道站域可 持续开发、塑造合理的郊区职住空间关系提供参考。

As an important node that directly links the rail transit system to the urban space，the railroad station gathers the resident population and the employment in the surrounding area of the railroad station ( referred to as the station area) to support the optimization of urban spatial structure． This study used Shanghai data to analyze the gathering level of residential population and employment in rail station areas at different ring layers of the city and classified rail station areas into 2 major types ( the employment type and the residential type) ，8 small classes based on job-housing density levels． Considering the urban activity center system planning，urban main center—urban sub-center—regional center，in“Shanghai Urban Master Plan ( 2016-2035) ”，the degree of support for urban central system was proposed based on the job-housing density of the railroad station areas and the spatial coupling relationship between the railroad station and the urban central system． It is concluded that the gathering level of employment and residential population to suburban railroad stations is still in its infancy and the average job-housing density of the railroad station areas at several levels of city center is significantly different: urban main center ( 43 thousand per square meter) ＞ urban sub-center ( 15 thousand per square meter) ＞ regional center ( 13 thousand per square meter) ． Besides，38 sub-centers and regional centers with low supporting degree that need attention in subsequent urban renewal were identified． This study will provide a reference for the sustainable development of railroad station areas in the urban sub-center and regional center of the suburbs，and for the rationalization of suburban job-housing spatial relationship．
