英文摘要	To analyze the impacts of dust storms on the atmospheric and meltwater environment, intensive and simultaneous sampling for aerosols and meltwater on the terminal moraine (41 degrees 73 ' N, 79 degrees 88 ' E, 3,789 m a.s.l.) of Qingbingtan Glacier No. 72 (Glacier No. 72) on the northern margin of the Taklamakan Desert were conducted during the summer of 2008. Aerosol and meltwater chemistry (including the species of Na+, K+, Mg2+, Ca2+, NH4 (+), Cl-, SO4 (2-), and NO3 (-)) was analyzed by ion chromatography. The results indicated that the major anions and cations in the samples were SO4 (2-) and Ca2+, respectively. In the dust event, the average value of aerosol ions was 566.91 neq center dot m(-3), which was nearly five times that under nondust conditions (115.58 neq center dot m(-3)). In addition, in the meltwater samples, the sum of ion concentrations ranged from 31.26 to 180.98 mg center dot L-1, with an average of 76.40 mg center dot L-1. When a dust storm occurred, the ion concentrations in these two media increased significantly and simultaneously, but with different trends due to the different influencing factors. That is, the atmospheric environment was significantly affected by the dust storm. According to the correlation analysis and principal component analysis, the water-soluble ions, such as SO4 (2-), Cl-, Na+, K+, Mg2+, and Ca2+, originated from natural sources, while NH4 (+) and NO3 (-) originated from anthropogenic sources. The results of the air mass trajectory suggested that the regional dust storms caused by the air masses originating from Eastern Europe and Siberia had a significant influence on the glacial environment.
