Abstract: Snow chemistry on the glaciers of high mountains is good indicator for atmospheric environment change research. During the summer of the years from 2004 to 2007, we measured the characteristics of snow chemistry in three snowpits of different altitudes on the Haxilegen glacier No.51 of Kuytun, the eastern Tianshan Mountains of China. Correlation analysis and sea-salt tracing methods were used in this study to find out the source of major ions and dust particles. Results showed that the insoluble dust micro-particles and major ions in the snow had obvious seasonal variation. During Asian dust period, the concentration was significantly high, but the concentration was relatively low during non-dust period, which may be caused by dust activities of central Asia. The major ionic concentration was Ca²⁺>SO₄^2->NH₄⁺>NO₃^-> Cl^-> Na⁺>Mg²⁺>K⁺, Ca²⁺ was the dominate cation, and SO₄^2- was the dominate anion. The ionic correlation coefficient analysis shows that all the ions have very good correlation coefficient except the NO₃^-. The glacier regions was mainly affected by dust activities. Moreover, the major ions, especially Na⁺, was significantly affected by the Ocean in the west, as the precipitation was mainly from the west, besides those partly originated from the dust sources of central Asian region.
