摘　　要：On the plateau,symmetrical(WDS)and asymmetrical(WLS)dressing habits have been developed to adapt to the extreme climate of the plateau,which is characterized by large temperature variations.Few studies have investigated the impact of these dressing styles on the heat loss and thermal comfort of the Xizang people.To better characterize these impacts,models representing local heat loss of human are developed,and human heat loss experiments are conducted on the plateau.The results showed that the WLS increased the total heat loss of the participants by a range between 7.2%and 25.7%compared to the WDS;however,WLS narrowed the range of localized heat loss and reset the distribution of heat loss intensity.Adopting the WLS,the localized convection and radiation heat loss reported in the right sleeve was higher than that of the WDS by a range of 3.1 to 12.5 W/m^(2)and 5.2 to 22.5 W/m^(2),respectively.Also,the results of thermal neutral temperature of the participants increased by 2℃ when the WLS was utilized.Focusing on the distribution of heat loss to achieve localized insulation through clothing thermal regulation is an effective strategy to achieve human thermal comfort and energy savings.
