摘　　要：通过问卷调查确定影响北京居住型轨道交通站点周边步行便捷性、舒适性的关键性要素--分别为绕路程度和底层商业设施,针对其开展量化研究。选取13个典型站点,计算站点地区500m圈现状与假设社区开放后的绕路系数,并将现状与国内外其他城市作对比;调研站点周边500m圈街道底商分布情况,并对回龙观站进行详细研究。得出北京居住型站点周边绕路情况较为严重,封闭社区、路网形态等因素对绕路系数均有较大影响;超过半数的站点周边形成了较为连续的底商,部分站点周边底商极少;回龙观站500m圈每百米街道底商个数仅2.42,远小于适宜步行的标准。Firstly, the key factors affecting the convenience and comfort of walking around Beijing residential rail transit stations were confirmed through questionnaire, the most significant factors respectively are the degree of walking detours and the street ground-floor commercial facilities, then quantitative researches were carried out on the two factors. 13 residential stations in Beijing were selected, and the Pedestrian Route Directness value both under current situation and the scenario of open communities were calculated, moreover, the current situation was compared with other domestic and foreign cities. The distribution of street ground-floor commercial facilities around 13 stations was investigated, and the Huilongguan station was analyzed in detail. The result shows that the degree of walking detours around residential stations in Beijing was relatively serious, and significant factors are, for instance, closed communities and road network. There are relatively continuous underlying commercial facilities over half of the sites, and the facilities around a few of stations were insufficient, the density of street ground-floor commercial facilities within 500 meters of Huilongguan station was 2.42 per 100 meters, which is far less than the comfortable walking standard.
