摘　　要：轨道交通中心型站点吸引各类要素的快速交互,并通过触媒与溢出效应,推动人口和产业的高密度集聚,进而形成城市高能活力热点与核心发展节点。研究以成都和重庆8个轨道交通中心型站点为例,基于街道尺度的人本视角,结合百度热力图、百度街景、POI等多源时空大数据,并建立中心型轨道交通站点街道与建成环境与活力的关联模型,对两者之间的关联机制展开定量研究。研究发现:中心型轨道站域活力热点分布具有单边型、多中心型、均衡型以及外围型4种模式。功能密度、功能多样性、步行可达性、开发强度等建成环境指标与站域活力正相关,但绿视率却与站域活力负相关。重庆的站域功能多样性对活力影响的回归系数高于成都,垂直、紧凑、复合的功能混合布局模式更适宜TOD中心型站点开发。最后,根据机制模型与现状,从功能、结构、形态3个维度提出中心型站点建成环境优化策略。The central metro station,facilitating the agglomeration of urban population and business,is regarded as the impetus of urban development.The study takes eight central metro stations in Chengdu and Chongqing as examples.Based on the humanistic perspective of street scale,the study combines Baidu heat map,Baidu street view,POI and other multi-source spatio-temporal data to build a correlation model between street and built environment and vitality of central rail transit stations to quantitatively study the correlation mechanism between the two.It is found that:(1)Functional density and diversity can significantly improve the station area street vitality,and the most significant effect of mixing is found by comparing the two places.(2)Improving the pedestrian accessibility and increasing the development intensity of the station area have a certain promotion effect on the street vitality of the station area.(3)Street green ratio has a certain inhibitory effect on the station area street vitality.Finally,suitable strategies for optimizing the built environment of the central station are proposed according to the current conditions.
