人本尺度下小城市街道空间适老性研究OA
Research on age-friendliness of street space in small cities from a human scale perspective
文章以张家口市主城区为研究对象,基于街景图像与语义分割技术,构建安全性、舒适性、便利性、健康性和社交性5个维度13项指标的测度体系,运用主成分分析法量化评价街道空间适老性.结果表明,张家口市街道整体适老性水平不佳且新旧城区分布不均,南侧经开区显著优于北侧旧城区.各维度问题突出,人行道有效宽度不足(68%采样点低于1.2 m)、过街设施缺乏、遮阳防晒效果差、休息设施密度低(0.005处/m)、绿视率偏低、社交空间缺失.研究表明采取低成本微更新策略较为可行,建议从安全通行、舒适环境、服务休憩、社交空间4个方面优化.
The article takes the main urban area of Zhangjiakou City as the research object.Based on street view images and semantic segmentation technology,it constructs a measurement system with 13 indicators across five dimensions:safety,comfort,convenience,health,and sociality.It uses principal component analysis to quantitatively evaluate the age-friendliness of street spaces.The results show that the overall age-friendliness of Zhangjiakou City's streets is poor,with uneven distribution between new and old urban areas;the economic development zone in the south is significantly better than the old urban area in the north.Each dimension has prominent issues,including insufficient effective sidewalk width(68%of sample points are less than 1.2 m),lack of crossing facilities,poor sun shading and protection,low density of resting facilities(0.005 per meter),low green view index,and lack of social spaces.The study indicates that adopting low-cost micro-renovation strategies is relatively feasible and suggests optimizing from four aspects:safe passage,comfortable environment,service and rest,and social spaces.
