摘　　要：优化公共坐具布局是提升商业步行街户外环境品质的重要措施之一。以北京王府井步行街中的公共坐具为研究对象,使用Ecotect对场地进行模拟并采集坐具投影遮挡数据,采用行为注记法调查人群的坐憩行为分布。通过SPSS线性回归分析研究坐具与行为的关联性,旨在证明坐具投影遮挡状况对坐憩行为存在较大影响。研究发现,坐具使用者数量在夏季与投影遮挡时长的相关性较强,在春秋2季的相关性较弱;此外,相较于业态类型和座位数量,坐具的投影遮挡率是影响坐憩行为最普遍的环境要素。依据研究时段内的投影遮挡模拟分析结果,对公共坐具布局提出优化建议,以期营造人性化的公共坐憩空间,提升商业步行街的商业和游憩价值。Optimizing the layout of public seats is an important measure to improve the outdoor environment quality of commercial pedestrian streets.Taking the public seats in Beijing Wangfujing Pedestrian Street as the research object,this research uses Ecotect to simulate the venue and collects the projection occlusion data of the seats,and adopts the behavior annotation method to investigate the distribution of sitting behavior of the crowd.Through the SPSS linear regression analysis to study the correlation between the seat elements and behavioral characteristics,the purpose is to prove that the projection of the seated occlusion has a greater impact on the sitting behavior of the crowd.It is found that the number of seat users has a strong correlation with the length of shadow shading in summer,but a weak correlation in spring and autumn;the projection shading rate of public seating is the most common environmental factor affecting the generation of sitting behavior compared to the number of seats and type of business.Then,based on the projected occlusion analysis of simulations during the study period,optimization suggestions are proposed for the layout of public seating,in order to create a humanized public sitting space and enhance the commercial and recreational value of the commercial pedestrian street.
