摘　　要：为研究西北干旱地区大气气溶胶物理特性,以新疆乌鲁木齐、阿勒泰、和田三个城市为研究对象,通过采用反向轨迹、潜在贡献因子(PSCF)和浓度权重轨迹(CWT),以及气溶胶吸收Angstrom指数计算方法,基于多源数据开展了大气气溶胶时空分布特征研究分析。相较于沿海城市,和田地区PM污染物浓度最高,阿勒泰地区PM污染物浓度最低,新疆内陆地区的SO_(2)和CO污染程度更严重,而NO_(2)污染程度有所减轻,O_(3)污染程度出现波动状态。In order to study and analyze the physical characteristics of atmospheric aerosols taking Urumqi,Altay and Hotan in the arid area of Northwest China as the research objects,the temporal and spatial distribution characteristics of atmospheric aerosols were studied and analyzed based on multi-source data by using the reverse trajectory,potential contribution factor(PSCF)and concentration weight trajectory(CWT).Compared with coastal cities,Hotan had the highest concentration of PM pollutants and Altay had the lowest concentration of PM pollutants.The pollution degree of SO_(2)and CO in inland areas of Xinjiang was more serious,while the pollution degree of NO_(2)reduced to some extent,and the pollution degree of O_(3)appeared fluctuated.The research results provided a basis for analyzing and studying the physical characteristics of atmospheric aerosols in arid areas of northwest China.
