摘　　要：选取北京7条地铁线路,在冬、夏季测试其车厢内的温度、相对湿度,以及CO_2和颗粒物浓度,并用统计方法对这些数据进行分析。结果表明,与GB/T 18883—2002、GB3095—2012和GB 9673—1996相比,除了夏季车厢内相对湿度满足标准外,温度以及CO_2和颗粒物浓度均不同程度超标,超标率在9.5%~82.7%之间;温度和相对湿度在线路间和季节性的差异显著,颗粒物浓度在线路间的差异显著,而CO_2浓度无线路间和季节性差异;温度、相对湿度,以及CO_2和颗粒物浓度均与客运量显著正相关。因此,北京市地铁车厢内空气品质较差,夏季车厢内空气品质优于冬季。客流量是影响地铁车厢内空气品质的重要因素,且室外空气污染在一定程度上也影响车厢内颗粒物的浓度。此外,地铁建成与投入使用时间长短以及屏蔽门系统等因素也会影响车厢内的空气品质。The temperature,relative humidity,CO2 and particle concentrations are measured on 7 subway lines in Beijing during winter and summer seasons,the collected data are analyzed by statistical methods.Compared with the standards of GB/T 18883-2002,GB 3095-2012 and GB 9673-1996,the results show that the relative humidity in summer could meet the standards,but the temperature,CO2 and particle concentrations obviously exceeded the standards,and the excessive rate is in the range of 9.5%~82.7%.Besides,there are significant differences in temperature and relative humidity between lines and seasons,also between the concentrations of particles,while the CO2 concentration has no significant difference between the lines and seasons.Temperature,relative humidity,CO2 and particle concentrations have significantly positive relation with passenger capacity.Therefore,the air quality in the compartment of Beijing subway is generally poor,only better in summer than in winter.The research shows that passenger capacity is an important factor affecting the air quality in subway compartment,and the outdoor air pollution can affect the particle concentration to a certain extent.In addition,factors like the subway built and operation time,the screen door system may also affect the air quality inside the compartment.
