| 中文摘要: |
| 在地理信息系统（Geographic Information System，GIS）技术支持下，以福州市地铁1 号线
作为研究对象，选取福州市三环快速路以内的城区为研究区域，构建城市公共交通网络，基于道路
密度、公交站点密度等计算模型分析福州市交通网络密度分布特征.通过时间距离、通达性系数和
服务区域面积三个指标度量地铁开通前后交通网络通达性及其空间格局变化. 结果表明：核心城
区道路资源和交通资源的分布存在极化现象;地铁1 号线开通后，重要交通节点之间的平均通行时
间距离缩短13.7 min；交通枢纽中心30 min 服务区域面积增加了6.1%;交通网络通达性格局从以鼓
楼区为中心的单核扩散格局转变为沿地铁走势的一核一轴向外扩散分布格局，城区基本形成40
min 交通圈，实现了福州市通达性整体优化. |

| This paper takes Fuzhou metro line 1 as a study case, use GIS technology to analysis the density distribution
characteristics of traffic road network in Fuzhou with road density and bus station density based on urban public transport
network. The indexes include time range, accessibility coefficient and service scope are calculated to measure the transit
network accessibility and its spatial pattern changes with the opening of the metro. The results show that the distribution of
urban road resources and traffic resources is polarized; Mean transit time between important traffic nodes is reduced by
13.7 minutes with the opening of the metro; 30 minutes of the hub service area increased by 6.1%. Pattern of transportation
network accessibility from Gulou centered mono-center diffusion pattern turning into a nuclear along the subway in a
spread outside the axial distribution pattern. 40 minutes traffic circle of the city formed, realizing the overall optimization of
accessibility in Fuzhou. |
