| 摘要: |
| 在湿热地区厦门开展户外热舒适实验，旨在探讨不
同季节下人体各躯体部位的热感觉与热舒适特征，分析微气候
因子对人体局部热舒适的影响。实验受试者按照既定流程在同
一地点进行多次实验。实验过程中收集了热环境数据与热舒适
问卷，分析了不同季节下户外热环境与人体整体、局部热舒适
之间的关系，结果表明：1)夏季人体整体和局部中性温度均
高于冬季；2)在偏热环境下，面部与颈部具有较高的热敏感
性，而在偏冷环境下则是背部与上肢；3)夏季面部、颈部热
感觉对整体热舒适度的影响最大，而在冬季则是胸部和背部；
4)气温和辐射是影响热感觉的主要气象因子，但对局部热感
觉的影响程度则存在差异；5)夏季热环境比冬季更容易令人
感到不适，在太阳直射下的夏季热环境更加恶劣。最后，基于
实验结论，提出了针对湿热地区人体局部热舒适的景观设计与

| Abstract: |
| This study conducted outdoor thermal comfort
experiments in the humid and hot city of Xiamen with the aim of
exploring the thermal sensations and comfort characteristics of
different human body parts in different seasons, and analysing the
impact of microclimatic factors on local thermal comfort. Multiple
experiments were carried out at the same location according to a
predefined procedure by the test subjects. Both thermal environment
data and thermal comfort questionnaires were collected during
the experiments. The relationships between the outdoor thermal
environment and overall and local thermal comfort in different
seasons were analyzed. The results showed that: 1) The neutral
temperatures of both the overall body and local body parts in
summer were higher than in winter. 2) In a hot environment, the
face and neck were more heat-sensitive, whereas the back and
upper limbs were more sensitive in a cold environment. 3) The
thermal sensations of the face and neck had the greatest impact on
overall thermal comfort in summer, while the chest and back had
the greatest impact in winter. 4) Temperature and radiation were the
main meteorological factors affecting thermal sensation, but their
impacts on local thermal sensations varied. 5) The summer thermal
environment was more likely to cause discomfort than winter, with
the thermal environment under direct sunlight in summer being
particularly harsh. Finally, based on the experimental conclusions,
this paper proposes landscape design and management strategies for
local thermal comfort in humid and hot regions |
