Due to global climate change, the frequency and intensity of heat-related disasters in cities are continuously increasing. Intraurban heat vulnerability may vary according to the spatial conditions of a detailed area, and it is important to consider spatial characteristics when planning to create a comfortable urban thermal environment. However, in terms of urban planning, analytical frameworks of heat vulnerability that systematically organize and define spatial indicators associated with the thermal environment are still rarely used. Thus, this study proposes an analytical framework of heat vulnerability that synthesizes the related spatial indicators of three consecutive stages: causal factors, outcome issues, and response strategies. We analyzed and reviewed various related studies focusing on causal urban indicators, heat-related urban issues and various response approaches. We identified various thermal environment-related indicators and systematically classified them according to their definitions (i.e., static or dynamic) and characteristics (i.e., the environment, infrastructure and humans). Finally, an analytical framework of heat vulnerability is introduced to examine the intraurban thermal environment. The proposed framework consists of 14 attributes for the three main stages of heat vulnerability we defined. This framework can contribute to decision-making in the urban planning process to ensure a comfortable intraurban thermal environment.

城市热环境规划中热脆弱性评估的分析框架


由于全球气候变化，城市中与高温相关的灾害的频率和强度不断增加。城市内部热脆弱性可能因详细区域的空间条件而异，因此在规划创建舒适的城市热环境时，考虑空间特征非常重要。然而，在城市规划方面，系统组织和定义与热环境相关的空间指标的热脆弱性分析框架仍然很少使用。因此，本研究提出了一个热脆弱性的分析框架，该框架综合了三个连续阶段的相关空间指标：致病因素、结果问题和应对策略。我们分析和回顾了各种相关研究，重点关注城市因果指标、与高温相关的城市问题和各种应对方法。我们确定了各种与热环境相关的指标，并根据它们的定义（即静态或动态）和特性（即环境、基础设施和人类）对其进行了系统分类。最后，引入了热脆弱性的分析框架来检查城内热环境。拟议的框架由我们定义的热脆弱性三个主要阶段的 14 个属性组成。该框架有助于城市规划过程中的决策，以确保舒适的城内热环境。
