摘要
步行是老年人最为常见的日常活动和交通方式,对促进老年人身心健康至关重要。然而,现有研究较少关注步行时长这一重要的强度表征,以及与之相关的人本尺度建成环境要素。文章利用成都市大规模居民出行调查数据分析60岁及以上老年人的单日步行时长,采用街景图像和遥感影像等多源数据测算多种社区建成环境要素,并建立多元线性回归模型,研究步行时长与社区建成环境要素之间的关联。结果表明:人口密度、道路密度、NDBI、休闲设施数量和绿视率等社区建成环境指标对老年人步行时长产生了显著的正向促进作用。最后,从“生活圈”“公共空间”及“慢行系统”三个方面提出了鼓励老年人步行活动的适老环境优化策略。
Walking,a fundamental activity and travel mode for the elderly,plays a crucial role in improving their physical and mental health.However,previous studies on the relationship between elderly walking and the built environment have paid limited attention to the indicator of daily walking time and its human-scale built-environment correlates.This study uses extensive survey data on residents’walking behavior in Chengdu to analyze the daily walking time of individuals aged 60 years or above,adopts multi-source data such as street view imagery and remote sensing data to assess numerous community-level built-environment factors,and establishes a multiple linear regression model to investigate the relationship between the elderly’s walking time and various built-environment factors.The results reveal positive correlations between walking time among elderly individuals and community-level built-environment factors such as population density,road density,NDBI,the number of recreational facilities,and the green view index.Finally,the study proposes improvement strategies for age-friendly environments,which focus on three aspects:“living circles,”“public spaces,”and“slow transportation system.”
