中文摘要	基于祁连山西段老虎沟冰川站2010年1月至2011年10月大气颗粒物观测数据,通过HYSPLIT-4后向轨迹模式,使用轨迹聚类分析、潜在源贡献因子法(PSCF)和浓度权重轨迹法(CWT),研究了老虎沟地区不同粒径颗粒物(PM_(10)、PM_(2.5)和PM_1)传输路径及潜在源区的分布。结果表明:①影响研究区的气流轨迹主要来自偏西方向,夏季还受到偏东气流方向的影响,3类颗粒物质量浓度存在显著的季节变化,表现为春、夏季节高、秋冬季节低的特点。② PSCF分析显示,春季颗粒物浓度高值与塔里木盆地东部和河西走廊西部等干旱半干旱地区沙尘向下游传输关系密切,夏季研究区颗粒物浓度高值的形成主要受到偏西方向的塔里木盆地周边、新疆北部、河西走廊西部等地区,以及研究区偏东方向的内蒙古西部、河西走廊、宁夏,甚至陕西西部等地区共同影响。③春季CWT 高值区分布在研究区西北和偏西2个方向,夏季CWT高值除了偏西方向上贡献,还有来自偏东方向河西走廊等地区的贡献。
英文摘要	From January 2010 to October 2011,we analyzed characteristics of atmospheric particulate matter based on the observed data of atmospheric particulates in the Laohuogou area,in the western Qilian Mountains.The HYSPLIT-4 backward trajectory model was used to simulate the transport patterns and potential source areas of different-sized particles.The results showed that the westerly jet flow affected the study area throughout the year,and the summer was influenced by the easterly airflow.Particulate matter concentrations showed significant seasonal changes,which were higher in spring/summer and lowered in fall/winter.PSCF analysis showed that the pollution of PM_(2.5) and PM_(10) in spring was closely connected with dust transmission from arid and semi-arid areas,such as the eastern Tarim Basin and western Hexi Corridor.High PSFC values in the air mass during summer mainly came from two areas:one was from the westward direction and included the Tarim Basin,northern Xinjiang,and the Western Hexi Corridor,and the other was from the eastward direction and included western Inner Mongolia,the Hexi Corridor,Ningxia,and western Shaanxi.Higher CWT values were distributed in the northwest and the west of the study area during the spring period.In summer,high CWT values also appeared from the Hexi corridor and other eastward areas,which demonstrate that they are the potential source areas of the particulate matter.
