摘　　要：高密度城市差异化的建成环境导致局地高温状况呈现出复杂异质特征。为理解“城市形态—局地高温”的空间特征与关联机制,制定气候适应型街区规划策略,推进气候适应型城市建设,以我国典型的亚热带高密度城市——香港地区为例,基于局地气候分区框架对其高温风险进行评估并识别热岛效应风险街区。进而,选取上环街区这一热岛效应风险街区为研究对象,分析局地气候分区视角下街区的建成环境特征,采用车载移动测量方法开展局地气候监测,量化城市建设引发的热岛效应对城市高温的加剧作用。在此基础上,提出高温适应导向下气候适应型街区的规划策略,并探讨将高温适应专项规划策略融入香港地区城市规划体系的实施路径。研究结果可为高密度城市应对高温问题,以及构建气候适应型街区提供策略支持与方法参考。Differentiated built environment results in complex heterogeneity in high-density cities under high-temperature.To help understand the spatial characters and correlation between urban morphology and local high-temperature,formulate climateadaptive street block planning strategies,and promote climate-adaptive urban development,the typical subtropical high-density city of Hong Kong is taken as an example to evaluate the the high-temperature risks and identify risky street blocks with heat island effect based on the Local Climate Zone framework.Sheung Wan street block is selected as the research subject to analyze the built environment characters,mobile vehicle-based measurement methods,and quantify the intensification of hot island effect on urban high-temperature.On this basis,climate-adaptive street block planning strategies in response to high-temperature are proposed,and the path of integrating climate-adaptive special planning strategies into the urban planning system of Hong Kong is discussed.The research results can provide a reference for the response of high-density cities to high-temperature and building climate-adaptive street blocks.
