| 摘 要： | 以天山乌鲁木齐河流域为例,运用参数比较法、相关分析法,对降水中粉尘颗粒物特征在高山区和郊区随时间变化特征及其差异进行研究.结果表明,降水中颗粒物的浓度、粒径分布及化学要素组成在两个取样点都具有明显的季节变化.颗粒浓度表现为冬-春季节升高而夏-秋季节降低,与降水量成反向变化,反映了降水受中亚沙尘活动的影响明显.颗粒在冬-...

| Abstract: | Chemical and environmental significance of insoluble particles in precipitation are studied using methods of parameter comparison and correlation analysis at alpine and rural sites on the Urumqi river valley in Tianshan Mountains.The HYSPLIT(Hybrid Single Particle Lagrangian Integrated Trajectory) model is also employed to examine the transport process of air mass and insoluble particles in this region.Results show that the concentration,the size distribution and the chemical constitutes of dust particles i... |
