摘　　要：针对城市热环境的调控中的瓶颈问题,本文提出了对城市地表红外辐射能量在大气窗口区8～14μm的透射性能进行分析的思路。在城市地表红外发射能量和大气窗口区透射率分析的理论分析基础上对6种典型城市地表材质的透射能量进行了量化分析。结果显示不同材质在大气窗口区的透射能量存在较大的差异性,这为城市热环境调控提供了新的思路,也为夏季空调能耗与城市热环境之间的耦合矛盾关系提供了解耦的可能性。This paper explored the characteristics of radiation energy from an urban surface and studied the atmospheric transmittance. Then, the infrared energy was determined, which penetrated the atmospheric infrared window, based on the analysis of atmospheric transmittance and urban radiation energy. Six urban materials were considered in this field investigation. The results indicated that different urban materials had different performance of radiation energy penetration of the atmospheric infrared window, which showed different urban materials may have potentially difference on the urban thermal environment.
