摘　　要：本文采用问卷调研与现场实测的方式对青岛地铁车厢内的空气品质进行了分析研究,得到了在不同乘客密度下乘客对车厢环境空气品质的主观评价,并分析了污染物在空间上的分布规律。通过研究发现,随着乘客密度的增加,车厢内的空气异味感升高,乘客对空气品质的满意率下降,可接受率升高。高密度环境下车厢内的CO_(2)浓度和颗粒物浓度值高于低密度环境,车中区域的CO_(2)浓度值始终高于车门区域。在高密度环境下,车门1.7 m处的CO_(2)浓度和颗粒物浓度值高于1.1 m处,而车中区域在1.1 m和1.7 m处无明显的差别。The air quality in Qingdao subway carriage is analyzed by questionnaire survey and field test.The subjective evaluation of passengers'ambient air quality at different densities is obtained,and the distribution of pollutants is analyzed.It’s found that as the density of passengers increases,the air odor in the carriage increases,and the passengers'satisfaction rate of air quality decreases,while acceptable rate increases.In the high-density environment,the CO_(2)concentration and the particulate matter concentration value in the carriage are higher than the low-density environment,and the CO_(2)concentration value in the central area is always higher than the door area.In the high-density environment,the CO_(2)concentration and the particulate matter concentration at 1.7 m of the door area are higher than 1.1m,while there has no significant difference between 1.1 m and 1.7m in the central area.
