基于风热环境评估的滨海城市生态通风廊道系统规划OA

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:①the wind speed in the central city has significantly decreased in the past 10 years,and the annual average temperature has gradually increased;②the surface temperature has gradually increased with the expansion range of the city during 2014-2021;③the 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.
