街道形态对室外热环境的影响研究
Research on the Influence of Street Morphology on Outdoor Thermal Environment
摘要
Abstract
In the context of global warming,the urban climatic environment is increasingly deteriorating.In order to create more livable urban outdoor thermal environments,grounded in the extreme climatic characteristics of Wuhan during the summer,this paper employs the Universal Thermal Climate Index(UTCI)and Mean Radiant Temperature(MRT)as indicators of human thermal comfort.Through simulation experiments,the urban morphological features of residential streets in Wuhan are investigated to analyze their impact on outdoor thermal comfort.The paper proposes the strategies for the optimization of the street design to enhance outdoor thermal comfort performance,and draws the following conclusions:when H/W=1.7,the outdoor thermal comfort and ventilation effect of the streets are relatively good;maintaining a street alignment rate of over 80%can balance outdoor thermal comfort with the need for activity spaces;and east-west-oriented streets exhibit a higher level of thermal comfort compared to other orientations.By comprehensively considering street morphology,this paper aims to provide a reference for health-oriented urban street planning and design in Wuhan.关键词
