摘　　要：城市轨道交通站点作为城市轨道交通系统与外界联系的重要门户,对其可达性的研究一直是交通领域的重要议题。通过分析出行者在城市轨道交通网络和城市街道网络出行方式的不同,利用ArcGIS网络分析模块和地理大数据平台构建基于时空花费的可达性评价方法,对站间可达性和站域可达性两个指标进行综合评价和可视化表达。以南京市为例进行实证研究,结果表明:受站点间距和换乘距离的影响,南京城市轨道交通站点站间可达性呈现以主城区和河西核心区为双核心的辐射分布;受到站点出入口数量、分布及街道通达性的影响,站域可达性呈现副城围绕主城的星团状空间分布。As an important gateway for urban rail transit system to connect with the outside world,the research on its accessibility has always been an important topic in the transportation field.By analyzing the different travel modes of travelers in the urban rail transit network and the urban street network,the ArcGIS network analysis module and geographic big data platform are used to construct an accessibility evaluation method based on space-time cost.Comprehensive evaluation and visual expression of the two indicators.Taking Nanjing as an example to conduct an empirical study,the results show that:affected by the station spacing and transfer distance,the accessibility of Nanjing urban rail transit stations presents a radiation distribution with the main urban area and Hexi core area as the dual core;influenced by the number,distribution,and street accessibility,the station accessibility presents a cluster-like spatial distribution of the sub-city around the main city.
