| 摘 要： | 在北京城区布点实测了冬季 (2000年1月26日~2月2日) 主要空气污染物 (SO2、NOx) 浓度的垂直分布以及边界层气象要素的分布, 并对该时间段内气象条件和污染物浓度分布之间的关系做了初步分析。结果表明:在不利于扩散的气象条件下, 污染物浓度剧增; 随着气象状况的交替变化, 污染物浓度也呈交替变化的规律; 在同一建筑物的不同高度, 污染物浓度分布存在差别; 在同一建筑物不同朝向处, 污染物浓度也存在差异, 特别是在不利扩散的气象条件下, 空气质量差异可达一个级别。此外, 城南和城北处的污染物浓度也有显著的差异。

| Abstract: | The concentration of the main air pollutants (SO 2,NO x) were measured from 26 Jan. to 2 Feb. in 2000 in the Beijing urban districts. Utilizing the measured data, a preliminary research on the relation between the weather condition and air pollution is made. The results show that the concentration of air pollutants increases sharply in the condition unfavorable to air diffusion. Along with the changes of the weather condition,the concentration of air pollutants varies correspondingly. Furthermore, at the same height, different resuls are obtained in the rooms of different direction, which is much more obvious in the weather conditions unfavorable to air diffusion. |
