中文摘要	为了解北京市大气悬浮颗粒物随时间的变化规律,对北京市2000年全年的总悬浮颗粒物(Total Suspended Par-ticulates,TSP)和可吸入颗粒物(Inhalation Particle Matter,PM10)观测结果进行了统计分析。结果表明:颗粒物浓度春季最高,夏季最低,TSP浓度和PM10浓度有良好的线性关系(相关系数为0.77)。通过后向轨迹分析得出,发生在2000年4月6日和25日的2次强沙尘天气的沙尘源地位于蒙古国的东南部和内蒙古的中西部。; In order to understand the temporal variation of the atmospheric suspended particulates in Beijing,the observational data of the Total Suspended Particulates(TSP) and inhalation particle matter(PM10) during the whole year of 2000 was analyzed.The result showed that the suspended particulates concentration exhibited a distinct seasonal variation: the highest in spring and the lowest in summer.There was a good linear relationship between the concentration of TSP and PM10(correlation coefficient was 0.77).Back trajectory analysis indicated that the source region of sandstorm on 6 and 25 April,2000 probably originated from the southeastern part of Mongolia and the Midwest of Inner Mongol.
