摘　　要：城市高质量发展背景下,对滨海城市的风热环境评估是建构城市生态通风廊道的重要前提。文章选取天津中心城区为研究对象,运用遥感影像对天津市风热环境进行评估,结果表明:(1)中心城区近10年风速明显减小,年平均气温逐渐升高;(2) 2014—2021年,地表温度随城市扩张而逐渐升高;(3)中心城区热岛效应逐渐增强,热岛中心有逐渐向外围扩张的趋势。文章提出保护生态补偿空间、优化风道作用空间、构建空气引导通道的策略,构建滨海城市中心城区的通风廊道系统,为缓解热岛效应提供理论依据。In the context of high-quality urban development,wind and thermal environment assessment of coastal cities is an important prerequisite for the construction of urban ecological ventilation corridors.The paper selects the central urban area of Tianjin as the research object,and then conducts wind-thermal environment assessment with remote sensing images.The results show that:(1) the wind speed in the central city has significantly decreased in the past 10 years,and the annual average temperature has gradually increased;(2) the surface temperature has gradually increased with the expansion range of the city during 2014-2021;(3) the heat island effect in the central city has gradually increased,and the heat island center gradually has the tendency to expand to the periphery.It proposes the strategies of optimizing the airway action space,constructing the guiding channel,and protecting the ecological compensation space so as to construct the ventilation corridor system in the central city of coastal cities,which provides the theoretical basis for alleviating the heat island effect.
