摘　　要：热中性温度是评价户外热环境感受的基础。围绕杭州西湖景区展开户外热中性温度研究,使用中位数法与热感觉投票TSV=0法,讨论以在杭大学生为代表的青年群体的季节性热中性温度、热中性温度范围和热可接受温度范围,通过分析热感觉投票TSV与热评价指标生理等效温度PET的关系,选取更适合研究地点的中位数法得出热评价结果。研究发现:杭州西湖景区全年热中性温度为21.0℃、热中性温度范围为12.0~23.9℃,热可接受温度范围为13.0~25.7℃,到访杭州西湖的青年人群对春秋季的热环境接受度最高,对冬季的热环境接受程度最低。经验模型表明空气温度和平均风速是影响青年群体热评价的关键原因。研究结果可为相似气候地区的热评价提供参考依据。The thermal neutral temperature is the foundation for evaluating the outdoor thermal environment sensation.This study aims to investigate the thermal neutral temperature of outdoor space of Hangzhou West Lake.Both the median method and the thermal sensation vote TSV=0 method are adopted to discuss the seasonal thermal neutral temperature,thermal neutral temperature range and thermal acceptable temperature range of a youth group represented by college students in Hangzhou.By analyzing the relationship between the TSV and the thermal evaluation index PET,the median method more suitable for the study site is selected to obtain the thermal evaluation results.It is found from study that throughout the year,the thermal neutral temperature of Hangzhou West Lake scenic area is 21.0℃,the thermal neutral temperature range is 12.0~23.9℃,and the thermal acceptable temperature range is 13.0~25.7℃.The youth group visiting Hangzhou West Lake has the highest acceptance of the thermal environment in spring and autumn and the lowest one in winter.Furthermore,the empirical models show that the air temperature and average wind speed are the key factors affecting the thermal evaluation of the youth group.This study can provide a reference for thermal evaluation in similar climate regions.
