摘　　要：对太原市2009年大气中可吸入颗粒物浓度进行了实时监测,得到月平均浓度值,并结合当年各月的平均风速和降水量进行分析,结果表明,采暖期内由供热锅炉以及各种采暖设施排出的大量废气污染物是引起太原市可吸入颗粒物浓度月均值变化的主要影响因素,另一方面,风速的增加会加速大气中可吸入颗粒物的扩散,而当风速较弱时,一定量的降水会对大气中可吸入颗粒物起到冲刷作用。In this study, it was monitored the inhalable particulate matter concentration in Taiyuan in 2009. Receive the monthly average concen- tration. The wind speeds and precipitation were combined to analyzing. The results showed that in heating periods, the exhaust gases from boilers and other heating facilities were the most important effect factor for the inhalable particulate matter concentration in Taiyuan. Meanwhile, the in- crease of wind speed can accelerate the spread of inhalable particulate matter in atmosphere. When the wind speed was small, the precipitation also purify the urban atmosphere.
