摘　　要：以韶山市城区的热环境为研究对象,利用Gambit软件建立了该城区建筑群的物理模型。分析了影响城区热环境的四种人为热源,通过Fluent软件模拟出夏季不同人为热影响因素作用下的城区热环境;并分析这些因素的影响程度。模拟结果表明:人类新陈代谢、工业、空调和交通四种不同的人为热对城区热环境有不同程度的影响,其影响程度大小依次为空调排热、新陈代谢排热、工业排热、交通排热,其中交通排热主要对路面周围热环境有影响。研究结果可以为改善城区热环境、缓解热人为热导致的热效应加剧提供参考依据。Urban thermal environment of Shaoshan city is the research object,a physical simulation model was built by software Gambit to analyze four kinds of anthropogenic heat,which influence the urban thermal environment. The urban thermal environment in summer under the influence of these four factors was simulated respectively by software Fluent and the effect degree of these factors was analyzed. The simulation results show that anthropogenic heat like heat release of human metabolism,industry,air conditioner and transportation had different effect on urban thermal environment and their effect degrees were presented orderly as follows： air conditioner heat release,human metabolism heat release,industry heat release and transportation heat release,transportation heat release mainly influenced thermal environment near road surface. The results could provide reference for improving urban thermal environment and relieving the effect of anthropogenic heat.
