在ArcGIS软件支持下，构建福州交通网络数据库，并结合多种数据和多种分析方法对福州地铁1、2号线路的交通进行了可达性评价．首先通过ArcGIS中的叠加分析、缓冲区分析、建模等手段对地铁沿线的道路网分布现状进行研究，发现地铁1、2号线建成后将大大缩短通行时间，提高了城市外围地区的交通可达性．其次，利用网络分析工具计算得出地铁将平均减少市民出行时间8.88 min，减少地铁沿线出行时间11.6 min，在出行高峰期的影响更为显著，可减少将近20 min．研究结果可为交通部门提供参考．

Based on ArcGIS software , a database of Fuzhou urban transportation was built and the traffic accessibility of its Line 1 and Line 2 subway , which are still under construction , was evalua-ted.Through overlay and buffering analysis , our study got the knowledge about roads density along Line1 and Line 2 stations, and found that the construction of these two lines would significantly de-crease the travel time within Fuzhou .At the same time, the transport accessibility in the periphery area of Fuzhou city would also be enhanced .On average, the subway system can save a city resi-dent′s travel time by 8.88 minutes and even by 11.6 minutes for those residents living alone the subway lines.During rush hours, the mean decreasing travel time can be as long as 20 minutes.
