摘　　要：20 0 1年 1～ 3月在中国科学院大气物理研究所 3 2 0m铁塔 1 0个不同高度 (3 2 0、2 4 0、2 0 0、1 40、1 0 0、80、47、1 5、8m和地面 )使用无动力扩散采样器对SO2 和NO2 日平均总量及夜间平均浓度进行了观测。结果表明 ,2 0 0m以下高度SO2 和NO2 浓度较大。北京城区不同高度大气中SO2 的浓度 1月份最高。NO2 浓度 1月份和 2月份呈现高值。不同高度SO2 和NO2Using non electric sampler for the sample collection, atmospheric sulfur dioxide and nitrogen dioxide have been measured at different altitudes ((320, 240, 200, 140, 100, 80, 47, 15, 8 m and the surface) of the tower in the Institute of Atmospheric Physics from January to March, 2001. The data show that the concentrations of SO 2 and NO 2 were high under 200 m altitudes. The maximum concentration of monthly average SO 2 was in January and the maximum concentration of monthly average NO 2 was in January and February. The positive correlation has been found between the concentrations of SO 2 and NO 2 and the intensity of inversion temperature.
