以青藏高原低压高寒气候的代表城市拉萨为研究对象,通过环境测试和热舒适的问卷调查,分析拉萨住宅建筑冬夏两季室内热环境及不同性别人群的热反应特点。分析结果表明:虽然女性冬季的服装热阻要高于男性,但冬季女性比男性感觉更冷;低压环境中男性热中性温度要低于女性,温度越低,男女中性温度的差值越大。拉萨居民对高原低压气候环境的热适应主要体现在对低压缺氧环境的生理适应、较强的太阳辐射带来的心理期望和对高寒气候的行为适应上。研究结果有助于揭示低压高寒环境下的人体热适应机理,同时对高原气候的热舒适标准制定有参考价值。 Taking Lhasa, a representative city of the low-pressure alpine climate in the Qinghai-Tibet Plateau, as the research object, the indoor thermal environment in Lhasa residential buildings in winter and summer and the thermal response characteristics of different gender groups were analyzed through environmental tests and thermal comfort questionnaires. The results show that although the thermal resistance of women in winter clothing is higher than that of men, the winter women feel colder than the male ones; the male ones in low-pressure environment are lower than those in women, and the lower the temperature is, the worse the difference between male and female neutral temperatures Big. Lhasa residents on the plateau low-pressure climate and environmental adaptation is mainly reflected in the physiological adaptation of low-pressure anoxic environment, the strong solar radiation to bring the psychological expectations and adapt to the alpine climate behavior. The results are helpful to reveal the human body’s thermal adaptation mechanism under the conditions of low-pressure and high-temperature, and have reference value for the formulation of thermal comfort standards in plateau climate.
