摘　　要：青藏高原太阳辐射较强,远高于同纬度低海拔地区。在室内外辐射突变环境下,高原人群对室内热环境的需求不同于室内稳态环境且没有准确描述。本文针对进藏和世居两种人群开展现场调研,并对高原室外辐射强度进行划分,获得两种人群的热反应特征。结果表明:高原人群从室外不同辐射强度进入室内的热中性温度需求不同,且与稳态环境下室内人群热需求存在差异。进藏人群从室外不同辐射条件下进入室内的热中性温度分别为23.5℃(弱)、21℃(中)和17.9℃(强),其中强辐射组下的热中性温度要低于室内稳态环境(19.2℃),而弱和中辐射下热中性温度要高于室内稳态环境。因此,本研究结论可为青藏高原等强太阳辐射地区的建筑热环境调节策略提供参考。Solar radiation is stronger on the Tibetan Plateau than at lower altitudes at the same latitude.Under the sudden change of indoor and outdoor radiation,the demand for indoor thermal environment of the plateau population is different from that of indoor steady-state environment and has not been accurately described.This paper conducted on-site research on Tibetan migrants and Tibetan residents,and classified the intensity of outdoor radiation on the plateau to characterize the thermal responses of the two populations.The results showed that the heat-neutral temperature demand of the plateau population entering the room from outdoors with different radiation intensities was different,and differed from the heat demand of the indoor population in the steady-state environment.The heat-neutral temperatures of the incoming Tibetan population entering the room from outdoors under different radiation conditions were 23.5℃(weak),21℃(medium),and 17.9℃(strong),with the heat-neutral temperature under the strong radiation group being lower than that in the indoor steady-state environment(19.2℃),and the heat-neutral temperatures under the weak and medium radiation being higher than that in the indoor steady-state environment.Therefore,the conclusions of this study can provide a reference for the thermal environment regulation strategy of buildings in regions with strong solar radiation,such as the Tibetan Plateau.
