购物出行在老年人的日常出行中占有很大的比重,为此,拟探讨分析老年人步行购物时对商业设施选择的空间影响因素,为提高老年人步行购物出行质量提出措施建议.选取上海市中心区3个典型住区中的老年人作为调研对象,将老年人对周边商业设施的使用强度作为因变量,并将老年人购物出行时步行路径的空间特征、商业设施的空间特征等数据作为自变量,运用多元线性回归分析,得出自变量对因变量产生的影响作用及其量级.结果显示:商业设施与社区的距离、无障碍设施的数量、步行过街次数等因素对老年人步行购物出行时选择商业设施具有重要影响,而商业设施室内外绿化配置面积、街道绿化面积、步行路面整洁度等因素对其影响较小.由此得出老年人在步行出行购物时,更多地关注空间环境质量中的安全性、方便性与舒适性等因素.在此结论的基础上,从空间角度出发,为提高老年人步行购物出行质量提出措施和建议.%Along with China's population aging degree increasing, all kinds of aging problems are increasingly outstanding. The studies aiming at the elderly group's daily activities, individual demand and travel characteristics have become the top priority. Walking is a major trip mode for the elderly, and shopping trips occupies a large proportion in their daily trips. This paper plans to analyze the influencing factors on choice of commercial facility for the elderly going shopping on foot and proposes measures to improve the quality of their walking shopping trips. This study selects the elderly in three typical residential communities in central Shanghai as the objects of survey,taking the utilization ratio of the commercial facility as the dependent variables, commercial facilities spatial features and the walking path spatial features as independent variables. A multiple liner regression model is established to discuss the impact of the multiple factors on the choice of commercial facilities for the elderly. The results shows: the distance between commercial facilities and community, the number of the barrier-free facilities, intersection and other facilities passing by, the scale of business facilities, and pedestrian passage width have significant impacts on the choice. However, the green area around the commercial facilities and street, the cleanliness of the street show minor influences on the choice. Thus, we can draw the conclusion that the elderly pay more attention to the distance between commercial facilities and community, safety, convenience and comfort in the walking environment than any other factors when they go shopping on foot.
