摘要：城市形态学研究应充分考虑气候因素，以及该因素对人类行为的影响。为了将这些见解付诸实践，本研究旨在调查夏季炎热干燥的阿尔及利亚Sidi Okba（Biskra）城市的不同城市环境，并确定PET指数的热舒适范围的上限和下限。次之的目标是量化步行环境并突出城市形态和步行行为之间的关系。该研究采用了问卷调查和步行审计工具相结合的方法。该研究的结果表明，由建筑密度，高/宽（H / W）比和树木密度定义的城市形态与室外热条件和短距离潜在行人显着相关。该研究还表明，为了提供舒适的气候并增加城市环境中的行人选择，公共空间应具备高建筑密度，这些建筑之间会有高度连接的街道，以及沿街植被。这种类型的设计对公共空间的步行性有积极影响。

Abstract: Urban morphology should carefully consider climatic and behavioural aspects for hot arid climates. To put these insights into practice, this study aims to investigate different urban environments in the hot, dry city of Sidi Okba, Algeria (Biskra) during the summer season and defines the upper and lower limits of the thermal comfort range for the PET index. A second aim is to quantify the walkable environment and highlight the relationship between urban morphology and walking behaviour. The study was based on physical measurements combined with a questionnaire survey and a walking audit instrument. The findings from this research show that urban morphology, defined by building density, height/width (H/W) ratio and tree density, is significantly associated with the outdoor thermal conditions and potential pedestrians over short distances. The study also shows that in order to provide a comfortable climate and to increase pedestrian choice in the urban environment, the public space should include high building density, combined with deep streets with a high connection between them, and a large amount of vegetation along the lower parts of streets. This type of design has a positive effect on the walkability score of public spaces.
