A year-long longitudinal survey regarding perceptions of outdoor thermal conditions and thermal comfort was conducted in Xi'an, a City in a Chinese cold region. The survey included micrometeorological measurements and a longitudinal questionnaire. The thermal comfort and adaptability of southern Chinese (people from Changsha and Guangzhou) and northern Chinese (people from Xi'an) in Xi'an were studied from the three aspects of psychological, physiological, and behavioral differences. The results of similar studies in other regions were compared with those of this study. Regarding psychological differences, northerners were more adapted to Xi'an's climate than southerners, with an expected temperatures of 20.7℃ and 24.1℃ for northerners and for southerners, respectively. Regarding physiological differences, the neutral temperature of the northern population was 22.12℃, while that of the southern population was 21.12℃. The neutral temperature for the southern population in Xi'an is similar to that of northern people living in Xi'an. Regarding behavioral differences, northerners were more likely than southerners to maintain their thermal comfort by adjusting their clothing when they experienced a change in the outdoor environment. This study not only indicates that there were differences regarding the thermal comfort of people originating different regions but also provided support for fully explaining the mechanism of climate adaptation of human thermal comfort. In addition, this work provides basic data regarding formulating outdoor thermal comfort standards and provided data support for personalized thermal comfort.
在中国寒冷地区的城市西安进行了一项为期一年的关于室外热环境感知和热舒适度的纵向调查。该调查包括微气象测量和一份纵向调查问卷。从心理、生理和行为差异三个方面研究了南方人（来自长沙和广州）和北方人（来自西安）在西安的热舒适度和适应性。将其他地区类似研究的结果与本研究的结果进行了比较。在心理差异方面，北方人比南方人更适应西安的气候，北方人和南方人的预期温度分别为20.7℃和24.1℃。在生理差异方面，北方人群的中性温度为22.12℃，而南方人群的中性温度为21.12℃。西安南方人群的中性温度与居住在西安的北方人相似。在行为差异方面，当室外环境发生变化时，北方人比南方人更有可能通过调整服装来保持热舒适度。本研究不仅表明来自不同地区的人的热舒适度存在差异，而且为充分解释人类热舒适度的气候适应机制提供了支持。此外，这项工作为制定室外热舒适度标准提供了基础数据，并为个性化热舒适度提供了数据支持。
