摘要：对地铁站点分类不仅是研究站点交通吸引范围的重要依据，同时还可作为居民出行方式选择机理研究的指标。文章主要针对我国地铁站点的分类进行研究，利用聚类分析法分布广泛和处理问题灵活的特性，首先选取地铁站点的自身属性以及周围环境影响因素的多个变量的信息作为聚类量，对聚类量进行量化分析，然后利用最短距离法得出聚类表，通过聚类表对地铁站点进行分类，得出的冰柱图和树状聚类图能够直接表现地铁站点的分类结果，分类结果更具有直观性和全面性。文章选用哈尔滨地铁1号线车站站点为例进行分析计算，最终将地铁1号线化分为中央商务区换乘、单一功能、通勤出行、远途交通接驳转运、城市外围换乘以及日常出行6类站点。

Abstract：The classification of metro is not only the important basis of studying the attraction range of the traffic，but also can be used as an indicator of the mechanism of travel mode selection.This paper mainly studied the classification of subway stations.The method of cluster analysis that is widely used and flexible in dealing with problems was employed in this paper.First，the properties of subway stations and the surrounding environmental factors were selected as clustering variable，and then the shortest distance clustering method was used to get the clustering table.The classification of subway stations was then obtained by the clustering table.The dendrogam and icicle histogram were used to present the classification results intuitively and comprehensively.The Metro Line 1 in Harbin was selected and the classification results on the substations showed that Metro Line 1 can be divided into six types：central business district transfer stations，subway stations with single function，commuter travel subway stations，long-haul transport services transit subway stations，subway stations outside the city transfers，and daily travel subway stations.
