摘　　要：【目的】气候变化背景下,体力活动不仅受到客观建成环境与真实热风险影响,也受到主观心理感知影响。分析住区居民的热风险感知(heat risk perception,HRP)与体力活动的关系,为应对气候变化健康风险的城市规划研究与实践提供实证基础。【方法】以哈尔滨市为例,采用问卷调查和分层回归的方法,揭示了“恐惧”“态度”和“适应”3个维度上的HRP水平与体力活动水平分别在不同局地气候分区(local climate zone,LCZ)类型的住区中的差异以及二者间的关系。【结果】HRP与体力活动相关,其中恐惧和态度感知减少了体力活动,适应则增加了体力活动;HRP能够显著提高住区建成环境与体力活动模型的准确性,开放型中层住区居民具有最低的恐惧和态度感知水平,以及最高的适应感知水平和体力活动水平。【结论】从风险感知视角揭示了气候变化和建成环境对居民健康的间接影响,为城市气候安全治理和健康城市规划提供参考。[Objective]As climate change and global warming continue to intensify,it is crucial to understand how appropriate urban built environments can mitigate the adverse effects of climate change stress and heat risk.However,less attention has been paid to the role of individual perception and behavior in response to climate change.Research has identified a set of psychological factors that dominate the process of decision-making in the face of climate change and heat risk,known as climate change and heat risk perception(HRP).Nevertheless,there is a lack of research exploring how urban residents'perception of heat risk in the context of climate change might affect their physical activity in the built environment.[Methods]To address the aforesaid research gap,this research focuses on the residential areas in Harbin's built-up area.The World Urban Database and Access Portal Tools(WUDAPT)method is used to identify the LCZ types within these areas.A stratified sampling approach is then employed in five typical residential areas to gather data through questionnaire surveys.These surveys mainly collect information on residents'HRP and physical activity levels,aiming to understand the differences and relationships between HRP levels in the dimensions of“fear”,“attitude”and“adaptation”and physical activity levels across residential areas with different LCZ types.[Results]1)This research suggests that HRP is indeed related to physical activity level.It is found that fear and attitude perceptions can reduce physical activity level,while adaptation perception can improve physical activity level.Additionally,HRP can significantly improve the accuracy of the built environment and physical activity model.Residents in residential areas with open layout and moderate density exhibit the lowest fear and attitude perceptions,as well as the highest adaptation perceptions and physical activity levels.2)This research provides valuable insights into the indirect impacts of climate change and the built environment on residents'hea
