Abstract

Previous research has found that components of the natural and built environment play an important role in regulating ambient temperature. However, existing research regarding the association between these environmental characteristics and thermal exposure has focused mainly at the macro level, leaving this relationship at the individual level underexplored. It remains unknown how the environment functions differently in determining thermal exposure among various types of trips and how this mechanism differs by gender. Using GPS walking trajectory data collected in Nanjing, China, this study examines the extent to which male and female pedestrians experience different levels of thermal exposure, and how the thermal exposure determinants work differently between utilitarian and recreational trips. Descriptive analysis shows that men experience higher per-minute thermal exposure than women, and both male and female pedestrians face higher thermal exposure per minute during utilitarian walks compared to recreational walks. Generalized linear mixed model results indicate that green spaces significantly reduce thermal exposure for both male and female pedestrians during utilitarian walking trips, but this effect only works among women regarding recreational walking. We also identified a negative relationship between water bodies and thermal exposure during recreational walks, but this correlation only occurs among women. Our study suggests that the natural environment’s mitigating effect on thermal exposure differs by gender among different types of walking trips. Policymakers should consider these disparities to avoid exacerbating gender inequality in the arena of thermal exposure and health.

探索行人热风险暴露及其在各类步行出行中的决定因素:南京基于 GPS 的性别研究
以往的研究发现,自然环境和建筑环境的组成部分在调节环境温度方面发挥着重要作用。然而,有关这些环境特征与热暴露之间关系的现有研究主要集中在宏观层面,而对个体层面的这种关系则缺乏探索。人们仍然不知道环境在决定各种类型旅行的热暴露方面有何不同,也不知道这种机制在性别上有何差异。本研究利用在中国南京收集到的 GPS 步行轨迹数据,研究了男性和女性行人在多大程度上经历了不同程度的热暴露,以及热暴露决定因素在功利性出行和娱乐性出行中的不同作用。描述性分析表明,与女性相比,男性每分钟的热暴露量更高,与休闲步行相比,男性和女性行人在功用性步行时每分钟的热暴露量都更高。广义线性混合模型的结果表明,绿地能显著减少男女行人在功用性步行中的热暴露,但这种效应只在女性休闲步行中有效。我们还发现水体与休闲步行时的热暴露之间存在负相关关系,但这种相关性只发生在女性身上。我们的研究表明,在不同类型的徒步旅行中,自然环境对热暴露的缓解作用因性别而异。政策制定者应考虑这些差异,以避免在热暴露和健康领域加剧性别不平等。
