  • 摘要: 基于2016年兰州市采暖期采集的气溶胶样品的水溶性离子系列分析，对兰州市大气污染特征及其主控因素和来源进行了深入探讨.结果表明，近年来兰州市大气中，NO3-、SO42-、Ca2+和NH4+是兰州市冬季气溶胶样品中主要的离子成分，占到总离子浓度的88.12%，以人为污染源排放污染物的二次转化为主，其中NO3-、Ca2+近年来有增加趋势.对兰州市污染物及离子来源分析发现兰州市冬季二次污染比较严重，机动车排放污染物所占比重增大.冬季到达兰州市的气团以武威-兰州为首；腾格里沙漠和黄土高原西南部是冬季PM10污染的主要贡献源区，兰州市自身和白银市是NO2污染的主要贡献源区.整体来看，兰州市空气质量有了很大的改善，NO2、PM10是目前最需要解决的两大污染问题.
    Abstract: Based on the analysis of aerosol samples collected during heating period in Lanzhou City in 2016, the characteristics of atmospheric pollution and its main controlling factors and sources were discussed. The results show that the main ionic components in the winter were NO3-,SO42-,Ca2+ and NH4+, accounting for 88.12% of the total ion concentration. The secondary transformation of pollutants from anthropogenic sources was the main factor. NO3- and Ca2+ have been increasing in recent years. Based on three-phase clustering and the analysis of potential sources of pollutants, it was found that the secondary pollution was serious in the winter in Lanzhou, and the proportion of pollutants emitted by motor vehicles increased. The air mass arriving in Lanzhou was led by Wuwei-Lanzhou. Tenggri desert and southwestern of Loess Plateau were the main sources of PM10 pollution in winter. Lanzhou City and Baiyin City were the main sources of NO2 pollution. Overall, the air quality of Lanzhou has greatly improved.
