根据2013 - 2016年兰州市大气气态污染物和颗粒物的逐时浓度数据，分析了兰州市大气污染物的特征、潜在来源及其变化趋势。SO2、NO2、CO、8-hO 3、PM2.5和PM10的平均浓度分别为25.2 ± 16.0 μg m−3、46.5 ± 21.1 μg m −3、1.3 ± 0.7 mg m−3、77.8 ± 45.5 μg m−3、58.7 ± 32.9 μg m−3和131.1 ± 86.2 μg m−3。SO2、PM10和PM2.5浓度呈下降趋势，NO2、CO和O3浓度呈上升趋势。PM是最常见的主要污染物，其值远高于标准限值。但NO2污染有明显的超标趋势，兰州市的NO2污染较全国其他城市严重。空气污染物与气象参数的关系表明，较低的主要污染物与较高的风速从北部和西部。模拟后向轨迹表明，冬季大气污染物浓度高与河西走廊和内蒙古气团的输送有关，春季PM10浓度高与新疆沙漠地区沙尘的远距离输送有关。和中亚。初步分析了当地污染物排放和气象条件的影响。空气质量的改善可能与严格的排放控制导致污染物排放量的减少有关，气象条件的贡献不明显，有待进一步研究。
Airborne pollutant characteristics, potential sources, and variation trends of cause are investigated based on the hourly air concentrations of gaseous pollutants and particulate matter from 2013 to 2016 in Lanzhou. The mean concentration of SO2, NO2, CO, 8-hO3, PM2.5, and PM10was 25.2 ± 16.0 μg m−3, 46.5 ± 21.1 μg m−3, 1.3 ± 0.7 mg m−3, 77.8 ± 45.5 μg m−3, 58.7 ± 32.9 μg m−3, and 131.1 ± 86.2 μg m−3, respectively. The concentrations of SO2, PM10, and PM2.5present decreasing trends while NO2, CO, and O3present increasing trends. PM is the most frequent major pollutants with much higher value than standard limit. However, NO2pollution had obvious trends to reach the limit and was more serious in Lanzhou compared with other Chinese cities. Relationship between air pollutants and meteorological parameters suggested that lower primary pollutants were associated with higher wind speed from north and west. Modeled back trajectory demonstrated that the transport of air masses from the Hexi Corridor and Inner Mongolia was responsible for the high concentrations of the air pollutants in wintertime, and high PM10level in springtime was related to long-range transport of dust from desert areas of the Sinkiang and the Central Asia. Effects of local pollutant emissions and meteorological condition were preliminary analyzed. Improvement of air quality might be related to the decreasing of pollutant emissions due to strict emissions controls, and the contribution of meteorological condition was not explicit and should be further investigated.
