| 摘 要： | 本研究利用大气超级站对乌鲁木齐市4月9日至10日沙尘天气过程,粒径谱、离子和重金属组成及变化进行分析。研究结果表明激光雷达观测结果与环境空气质量监测基本一致;小粒径颗粒在沙尘和非沙尘时段含量最多,但在沙尘时段大粒径颗粒的增长幅度远大于小粒径;沙尘过程中的离子主要来源于土壤一次源;沙尘过程中地壳元素浓度及占比均显著升高,会稀释环境空气中人为污染元素。

| Abstract: | In this study,the particle size spectrum,composition and variation of ions and heavy metals in the sandstorm weather of April 9-10 in Urumqi were analyzed by using the atmospheric super station.The results indicated that the Lidar observations are basically consistent with the ambient air quality monitoring.Small-sized particles have the most content in sand and non-sand periods,but the growth of large-sized particles is much larger than that of small-sized particles during sandstorm periods.The ions in sandstorm process mainly come from soil primary source,and the concentration and proportion of crustal elements increase significantly in sandstorm process,which will dilute the ambient air artificial pollution elements. |
