| 摘 要： | 通过对贺兰山地区大气背景、浮尘、扬沙和沙尘暴天气的采样，得到在不同天气条件下的气溶胶质量浓度，而且在它们之间存在一定的倍数关系。由Anderson和KB－120E采样器得到的总浓度是有差异的。 |

| Abstract: | Aerosol mass concentrations were obtained under different weatherconditions including atmospheric background, dust, sand-blowing and dust storm, and there are largelg differences for averaged aerosd mass concentraions under above four kinds of different dust and sand weather conditions. On the average, the aerosol mass concentrations of dust weather is 3.54 times larger than that of atmospheric background; of sand-blowing, 2.95 times larger than that of dust; of dust storm, 2.68 times larger than that of sand-blowing. The sand aerosol mass concentrations of background in the Helan Mountain vary from 76.0 to 142.4 μg.m-3 in spring, and also the average value in desert area is more than the value in Yinchuan 20%. Furthermore, the mass concentrations between Anderson and KB-120E are different . |
