以广州地铁网络为研究对象，使用ArcGIS软件并以加权平均旅行时间为指标，分析了广州地铁网络的可达性。结果表明，高可达性地区集中在老城区，并圈层式向外围扩张，呈现出多级格局。在可达性较高的区域中，还呈现出指向换乘站的特点。研究还发现，可达性较高的地铁站点均位于市中心区域、人口密集区域。而可达性较低的站点全部位于缺少换乘点，且人口密度相对低的南沙区。

This paper used ArcGIS software and took the weighted average travel time as an indicator to study the accessibility of Guangzhou Metro network .The results showed that high accessibility areas are concentrated in the downtown and expand outside , showing a multi-stage pattern.There are some protruding parts in areas of high accessibility because of transfer stations .The study also found that metro stations with higher accessibility are located in the downtown and densely populated region .While the metro sta-tions with lower accessibility are located in Nansha area which is a relatively low population density area and lack of transfer stations .
