Аннотация
The characteristics of ion concentration were studied in snowpit samples collected from the GRHK glacier, the XDKMD glacier and the YZF glacier over the Tibetan Plateau. Samples of snowpits in these three glaciers were analyzed by ion chromatography and ion sources were also explored by correlation analysis. The results indicated that the concentration of Ca2+, Mg2+, Na+, Cl- and SO4(2-) increased from the GRHK glacier to the XDKMD glacier and to the YZF glacier, suggesting that the terrestrial matter were major origin from the south to north over the Tibetan Plateau. The concentration of Cl-, Na+ and SO4(2-) in YZF glacier was higher by many times than GRHK glacier and XDKMD glacier, Perhaps mainly come from the evaporation of salt lake and the weather of mineral salts in the Qaidam Basin. The sources of NO3-, K+ and NH4+; were complicated and it is not obvious for the indication of environment.
