人本尺度下小城市街道空间适老性研究
Research on age-friendliness of street space in small cities from a human scale perspective
摘要
Abstract
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.关键词
