The ion concentrations were studied in both four snow pits on Hami Miaoergou Flat-Topped Glacier and one snow pit on Haxilegen Glacier No.51 of Kuitun river in eastern Tianshan Mountain, and both snow pits were retrieved in 2004. The results show that the Ca²⁺, NO^-₃ and SO^2-₄, particularly Ca²⁺, are major ions in the snow of snow pits in both ablation and accumulation area and also in the ice of snow pits in accumulation area on Hami Miaoergou FlatTopped Glacier, where the relationships among major cation concentrations in snow of snow pits can be revealed by ion concentrations in the ice of snow pits, but the correlation between ion concentrations in the snow of snow pits and elevation is not obvious, which probably can be attributed to the narrow span of elevation and sparse snow pits on glacier. However, the good correlation between ion concentrations in the ice of snow pits and elevation indicates that the elution process weakened gradually with the elevation rise and temperature decrease. The SO^2-₄ and Ca²⁺ particularly SO^2-₄, are major ions in snow and ice of snow pits on Haxilegen Glacier No.51 of Kuitun river, where its ion chemistry in snow pits is different from that on Hami Miaoergou Flat-Topped Glacier, which is most likely related to the geographical location of Hami Miaoergou Flat-Topped Glacier that is located in the leeward site of the Taklimakan desert, Shanshan desert and Gurbantunggut desert, and also probably associated with the elution process in snow pits and altitude effect of deposition flux. The ratios (Cs/Ci) of NH⁺₄, NO^-₃ and K⁺ is bigger than that of Ca²⁺,Mg²⁺ and Na⁺ of snow pits in accumulation area on Hami Miaoergou Flat-Topped Glacier, and also the ratios of Na⁺ and NH⁺₄ is bigger than that of Cl^-, SO^2-₄, Mg²⁺ and Ca²⁺ of snow pits on Haxilegen Glacier No.51 of Kuitun river, which indicate that the signals of Ca²⁺ and Mg²⁺ in snow pits both on Hami Miaoergou Flat-Topped Glacier and Haxilegen Glacier No.51 of Kuitun river may be easier to be preserved in ice cores than other ions in snow pits. This guaranteed studies of ice core and reconstrution of paleoclimate records on these two glaciers.
