大连城市微观环境设计品质对步行行为的影响

The Association between Urban Design Quality and Walking Behavior in Dalian

缺乏运动导致的健康问题日益受到关注。微观城市环境品质作为宏观建成环境的补充,在行人的感知与体验中起到重要作用。研究通过人口密度、路网密度、设施可达性和宏观建成环境等指标进行多阶分层抽样选取样本社区;在社区范围内测量与可步行性相关的微观城市特征,包括客观建成环境,城市设计品质(可识别性、围合感、人性化尺度、透明度与复杂性)以及微观步行环境特征;进而应用负二项模型分析微观环境与步行人数的关联;研究结果表明城市意向、人性化尺度、透明度与微观步行环境都对行人步行具有显著影响。

Physical inactivity is one of the most important public health issues internationally. Micro-urban environment quality plays an important role in pedestrian perception and experience, as a supplement to the macro-built environment. This study seeks to validate specific micro-urban design measures in Dalian, China. First, it selects neighborhood sample through population density, road network density, accessibility, and other built environmental attributes while using multi-stage stratified sampling. Second, the walkability-related micro-scale environment is measured within the neighborhood, including the objective-assessed built environment, urban design quality (identifiability, enclosure, human scale, transparency, and complexity) and micro-pedestrian environment characteristics. Further, the negative binomial model has been applied to explore the association between urban design quality and walking. The results show that image of the city, human scale, transparency, and micro pedestrian environment all have a significant impact on pedestrian walking.
