摘要
乌鲁木齐市大气颗粒物和飘尘浓度日变化趋势基本一致,无论采暖和非采暖期均出现两个高峰和低谷。浓度变化主要和污染源日排放特征有关,其次受气象因素的影响,由此而引起的结果是:采暖期日变化规律图的峰形较钝,浓度波动的范围较小;非采暖期峰形较锐,浓度波动范围较大。
The variation tendency of aerosol and particulate contents shows no much difference from each other in the atmosphere of Urumqi. No matter wether it is during the period of heating or not,the peak va- lue and low value occur with regard to the content variation of aerosol and particulate.The monitoring results are showed thatthe content variation are mainly resulted from air pollution resource and also affected by cli- mate;rhe variation pattern of contents is that it vacies gently during heating period,quickly during another periods.
