街区空间形态对居民步行通行的影响分析

摘要

Walking in transportation is mainly short distance,but is the core in the construction of green transportation system.The paper chooses 21 residential blocks in downtown,Shanghai,selects spatial form factors of blocks correlated to pedestrian activities,studies the influence of the factors on walking by SPSS analysis,basic model simulation,and prediction modelling.With distribution map,the paper calculates the suitability of blocks and puts forwards improvement suggestions.%步行不仅在短距离出行中占据重要地位,还在大城市绿色交通体系构建过程中起着核心作用.文章以上海中心城区21个生活街区为研究对象,提取与居民步行通行活动相关的街区空间形态变量,通过SPSS相关性分析、基础模型模拟和预测模型建立三种方法探索街区建设环境变量对各类步行通行活动的影响,并结合散点图分析进行适宜值估算,在此基础上从街区空间形态角度提出步行友好街区的优化建议.
