| 摘 要： | 对兰州皋兰山顶春季大气气溶胶连续采样，得到了大气背景、浮尘、扬沙、沙尘暴等不同天气条件下的气溶胶质量浓度．通过沙尘天气的过程分析，得到不同沙尘天气条件下，TSP浓度的时间变化规律．与兰州大学小二楼顶的监测数据进行比较分析，可以看出兰州市的污染状况和TSP的时空分布．通过各类沙尘天气不同粒径气溶胶粒子的浓度分析，发现气溶胶粒子粒径的分布规律和气溶胶来源不同．

| Abstract: | The authors present the aerosol mass concentrations of background,dust storm,floating dust and blowing sand, monitored continuously atmospheric aerosol at the top of Gaolanshan in Lanzhou in the spring of 2002. After studying dust storm process,we present the rule of the atmospheric TSP (Total Suspend Particle) change with time under the different weather conditions. This paper also analyzes the TSP distribute and pollution conditions in Lanzhou by comparing data from Gaolanshan sampling site and Lanzhou University sampling site. During the study of the mass concentrations of different size grade particles that were sampled using Andeson aerosol collecting instruments under different weather,we get the distribution law of size grades of aerosol particles. The different size grade distribution may have different sources. |
