| 摘 要： | 主要对北京市三个采样点的PM10和PM2.5污染水平和时空分布进行了分析.结果表明:市区和西北城区PM10季节性变化一致,郊区与市区和西北城区有所差异,但污染水平最低.PM2 5随PM10上升而上升,但季节性变化与PM10变化不一致.PM2.5/PM10比值在3个采样点都为夏季最高.采样点间对比为:除了PM10西北城区2006年春季超过市区,其它均为市区＞西北城区＞郊区.这些结果可为颗粒物污染的进一步研究提供基础信息和建议.

| Abstract: | The average concentration levels as well as the spatial and temporal differences of PM_(10) and PM_(2.5) of three sites in Beijing were analysed.It shows that the seasonal comparisons in the urban tie with that in the northwest district,but the suburb was different from the urban and the northwest district and the level was the lowest.PM_(2.5) rose according to the PM_(10),but the seasonal comparison was not the same as PM_(10).The ratio of PM_(2.5)/PM_(10) was the highest in the summer at three sites.The level of particles among three sites was the urban>the northwest district>the suburb,besides PM_(10)in the northwest district was more than the urban in the 2006 spring.The analysis results povide basic information and suggestion for further study on particles in the atmosphere. |
