摘　　要：大气颗粒物污染对环境空气质量的影响不可忽视,对大学生的个人健康和舒适性构成威胁。通过为期半年的夏季和秋季的户外微气候测量和纵向问卷调查,研究了中国西安大学校园户外人群感知空气品质对热舒适的影响,结果表明:(1)在夏秋两季时(PET<32℃,PM_(2.5)浓度低于123μg/m^(3)),空气满意度投票和热感觉投票均呈正相关,即当受试者对室外环境的空气品质质量更满意时,他们对环境的TSV倾向于更热的投票。当人体对空气环境满意度越高时,对于环境的热舒适就越高。(2)进一步依据空气满意度将人群划分为满意组(PM_(2.5)浓度为7~40μg/m^(3))、中性组(PM_(2.5)浓度为41~79μg/m^(3))和不满意组(PM_(2.5)浓度为80~123μg/m^(3))时发现:在夏季和秋季,当PET范围在16~40℃,空气品质不满意组的人群的热感觉多为“Hot”(34.8%和1.3%),感到不满意的人群占比最高(15.0%和2.3%),其中夏季更为明显。(3)但当夏季PET高于32℃时,空气环境不满意组的热感觉投票值明显高于其他两组,夏季高于秋季。在高温环境下,空气品质不满意的人群的热感觉的变化幅度更明显(ΔTSV=1.1);对空气品质感到满意的人群对热环境舒适的比例高于不满意的人群,这对于夏季和秋季都是一致的。The impact of atmospheric particulate matter pollution on ambient air quality is significant and poses a threat to the personal health and comfort of university students.This study,conducted through a six-month outdoor microclimate measurement and longitudinal questionnaire survey during the summer and autumn seasons,examined the influence of outdoor air quality perception on thermal comfort among people in a university campus in Xi'an,China.The results showed that:(1)During the summer and autumn seasons(with PET<32℃ and PM_(2.5) concentrations below 123μg/m~3),there was a positive correlation between air satisfaction votes and thermal sensation votes,indicating that when the participants were more satisfied with the outdoor air quality,their TSV tended to lean toward a warmer vote.The higher the satisfaction with the air environment,the higher the perceived thermal comfort.(2)Further grouping participants based on air satisfaction into satisfied(PM_(2.5) concentration:7~40μg/m~3),neutral(PM_(2.5) concentration:41~79μg/m~3),and dissatisfied groups(PM_(2.5) concentration:80~123μg/m~3),the study found that in both summer and autumn,the thermal sensation of the dissatisfied group was predominantly "Hot"(34.8% in summer and 1.3% in autumn),with the highest proportion of dissatisfaction(15.0% in summer and 2.3% in autumn),particularly in the summer.(3)However,when the summer PET exceeded 32℃,the thermal sensation votes of the dissatisfied group were significantly higher than those of the other two groups,with the summer values higher than those of autumn.Under high-temperature conditions,the variation in thermal sensation among those dissatisfied with air quality was more pronounced(ΔTSV=1.1).Those satisfied with the air quality experienced a higher proportion of thermal comfort than those dissatisfied,consistent for both summer and autumn.
