%X Based on the streamwater samples collected at the Glacier No.72 of Qingbingtan from 1st to 31st August 2008, the hydrochemical characteristics were discussed. The results indicated that the anions and cations in streamwater were dominated by HCO3- and Ca2+. The order of major ion concentrations was: HCO3->SO42->Ca2+>Cl->Na+>NO3->Mg2+>K+>NH4+. The ion concentrations, which was influenced by the precipitation-effected water-rock exchange of ions with the debris cover, as well as the air temperature, varied similarly. Negative correlation was found between discharge of river and ion concentrations. The ions could be subdivided into three types, 1 Cl-, Na+, K+, Mg2+, HCO3- and SO42-, which may indicate the local sources; 2 NO3- and 3 Ca2 with complex sources. Rock and soil weathering was the main factors controlling ion concentration variation in steamwater.
