摘　　要：城市轨道交通系统在为人们提供巨大便利的同时,也带来了许多新问题,如噪音、粉尘等污染。对上海市、南京市轨道交通环控系统颗粒物质量浓度进行了实测分析,分别得出了不同系统站台、车厢环境颗粒物质量浓度随地铁运行的变化情况,以及冬、夏二季地铁环境颗粒物变化的异同,发现季节对轻轨系统颗粒物质量浓度的影响较地铁系统要大。结果表明,不同地铁环控系统均存在不同程度的PM_(2.5)超标,尤以半高安全门系统为甚。In this paper,we have done the measurement of particle concentrations in different environmental control systems of Shanghai and Nanjing urban rail transit during the typical seasons in 2013 and 2014. As a matter of fact,millions of passengers in the urban areas are depending on the subway systems in transportation for theirs being simple and convenient,at the expense of exposure to the particulate matters（ PM） as a major health concern in the megacities in the world today. To deal with the exposure problem,we have done the measurements on the change of PM concentrations at the station platforms of the light rail transit,which should be the gentlest,followed by the platform screen door（ PSD） and the security door system with full height,and the security door system with half height has been found the most serious in the change of PM concentrations. All in all,on the average,PM_（10） mass concentrations of the light rail transit at the station platforms and inside the train cabins have been worked out at about 109. 3 μg / m^3 and 69. 3 μg / m^3,respectively; What is more,the corresponding PM_（10） mass concentrations of the PSD system have been found 97. 3 μg / m^3 and 99. 6 μg / m^3; And the corresponding PM_（10） mass concentrations of the security door sys-tem with full height have been detected as 198. 8 μg / m^3and143. 3 μg / m^3; On the other hand,the corresponding PM_（10） mass concentrations of the security door system with half height,turn to be 271. 1 μg / m^3 and 229. 6 μg / m^3. Thus,both the station platforms and inside the train cabins have been found higher on the average PM concentration in winter than in summer. And it can be inferred that seasons are likely to influence the distribution of PM concentrations for the light rail transit the most. Particularly speaking,only PM_（10） concentrations of the security door system with half height prove to be above the standard set by the rail design specification limit（ 250 μg / m^3）. For PM_（2.5）,the mass concentra
