摘　　要：城市地铁站点空间布局的合理性对提高地铁运行效率、促进社会公平具有重要意义。以福州为例,基于多交通模式下的高德API出行实时大数据,采用高斯两步移动搜索法与双变量空间自相关分析法,探究“15分钟便民生活圈”单元尺度下,现阶段与第二期规划地铁建成后的地铁空间可达性与供需匹配特征。结果表明:现阶段15分钟时间阈值内,步行模式下地铁服务的人口覆盖率仅为23.55%,骑行模式下为55.74%,而在第二期规划地铁建成后,步行模式下地铁服务的人口覆盖率将达到42.82%,骑行模式下则会达到74.05%;时间阈值与地铁站点可达性之间呈现显著的正向关联;现阶段地铁高可达性区域主要集中在仓山区城门镇的周边区域,第二期规划地铁建成后,居民能享受到的地铁服务有显著提升,地铁高可达性区域则主要集中在长乐市樟港街道的周边区域;福州市地铁服务供需匹配度高,供需失衡的“15分钟便民生活圈”比例不超过2.38%。研究结果可为福州市地铁站点与“15分钟便民生活圈”的选址与规划提供参考与建议。The rationality of the spatial layout of urban subway stations is of great significance to improve the efficiency of subway operation and promote social equity.Taking Fuzhou as an example,based on the real-time big data of Gaode API travel in multi-traffic mode,the Gaussian two-step mobile search method and bivariate spatial autocorrelation analysis method are used to explore the spatial accessibility and supply-demand matching characteristics of the subway at the current stage and after the completion of the second phase of the planned subway under the unit scale of"15-minute convenience life circle".The results show that within the current 15-minute time threshold,the population coverage rate of subway service in walking mode is only 23.55%,and that in cycling mode is 55.74%.After the completion of the second phase of the planned subway,the population coverage rate of subway service in walking mode will reach 42.82%,and that in cycling mode will reach 74.05%.There is a significant positive correlation between the time threshold and the accessibility of subway stations.At present,the high accessibility area of the subway is mainly concentrated in the surrounding area of Chengmen Town,Cangshan District.After the completion of the second phase of the planned subway,the subway service that residents can enjoy has been significantly improved.The high accessibility area of the subway is mainly concentrated in the surrounding area of Zhanggang Street,Changle City;the supply and demand matching degree of subway service in Fuzhou is high,and the proportion of"15-minute convenience life circle"with unbalanced supply and demand does not exceed 2.38%.The research results can provide reference and suggestions for the location and planning of subway stations and"15-minute convenient living circle"in Fuzhou.
