摘　　要：研究旨在调查老龄化背景下的城市户外热舒适状况。研究选择成都市两个城市公园作为研究地点,以PET(生理等效温度)为指标,以563名老年人为调查对象,调查其在夏季、秋季和冬季对城市公园的主观热感知。同时,气象数据测量也与问卷调查同时进行。之后,文章对环境热舒适数据进行了预分析,然后进行热可接受分析与probit回归分析,以探讨老年人群体热舒适度的变化状况。研究得出以下结论:(1)受试成都地区老年人夏季热中性PET为27.01℃;热舒适PET范围为24.71~29.32℃。(2)成都老年人达到热舒适时的热感觉状态为:夏季“微冷”(TSV=-1.03),秋季“适度”(TSV=0.04),冬季“微暖”(TSV=0.71)。秋季是全年最舒适的季节(TCV=1.54)。The purpose of this paper was to investigate the urban outdoor thermal comfort in the context of aging.Two urban parks in Chengdu were selected as the study sites,and a subjective heat perception questionnaire was conducted to 563 elderly people as a background survey in summer,autumn and winter with PET(physiological equivalent temperature)as an index.At the same time,meteorological data were measured simultaneously with the questionnaires.After that,the environmental thermal comfort data were pre-analyzed,and then thermal acceptability analysis with probit regression analysis was performed to explore the changing status of thermal comfort in the elderly population.The following conclusions were drawn from the study:the summer thermoneutral PET of the elderly in the tested Chengdu area was 27.01°C,and the thermal comfort PET ranged from 24.71 to 29.32°C.②Thethermal sensory statesoftheelderly inChengdu when they reached thermal comfort were:"slightly cold"in summer(TSV=-1.03),“moderate”in autumn(TSV=0.04),and“slightly warm”in winter(TSV=0.71).Autumn was the most comfortable season of the year(TCV=1.54).
