为进一步明确寒冷地区城市公园老年人秋季热舒适特征及影响因素，结合微气候实测和热舒适调研的方法，通过与非老年人进行对比，分析了老年人室外热感觉与热舒适的关系特征，从热中性生理等效温度（physiological equivalent temperature, PET）、满足80%热可接受率的PET范围以及热偏好PET3个方面，划定了老年人热舒适评价标准，并探明了微气候因素对老年人热舒适的影响特征。结果表明：寒冷地区秋季城市公园中，相较于非老年人，老年人的耐热性较强，耐寒性较弱；老年人的热中性PET为8.3 ℃，非老年人为11.5 ℃，热可接受PET范围为3.2 ~ 28.0 ℃，非老年人为4.9 ~ 24.3 ℃，热偏好PET为25.8 ℃，非老年人为24.2 ℃；各微气候因素对老年人热感觉的影响程度由大到小依次为黑球温度>风速>相对湿度。

In order to further clarify the characteristics and influencing factors of autumn thermal comfort for elderly people in urban parks in cold areas, by combining the methods of microclimate measurement and thermal comfort investigation, comparing with non-elderly people, the relationship between outdoor thermal sensation and thermal comfort of elderly people was analyzed, and the evaluation criteria of thermal comfort for elderly people were defined from three aspects of thermoneutral physiological equivalent temperature (PET), PET range satisfying 80% of thermal acceptability and preferred PET. The influence characteristics of microclimate factors on the thermal comfort of elderly people were also explored. The results show that in the urban parks of cold areas in autumn, comparing with non-elderly people, the elderly have stronger heat tolerance and weaker cold tolerance. The thermoneutral PET for the elderly is 8.3 ℃, while that for non-elderly people is 11.5 ℃. The acceptable PET range is 3.2 ~ 28.0 ℃ for the elderly, while it is 4.9 ~ 24.3 ℃ for non-elderly people. The preferred PET is 25.8 ℃ for the elderly and 24.2 ℃ for non-elderly people. The degree of influence of each microclimate factor on the thermal sensation of the elderly is from large to small: globe temperature, wind speed, and relative humidity.
