Abstract: Based on the different water samples collected at the Glacier No. 72 of Qingbingtan in August 2010,the stable isotopes characteristics and hydrograph separation were discussed in this paper. The results indicated difference of oxygen- 18 and deuterium existed among the river water,glacier meltwater and rainfall samples.According to the relationship between δ18O and δD of stream,glacier meltwater and rainfall,the stream flow of Glacier No. 72 of Qingbingtan catchment was separated into components of glacier meltwater and rainfall. In summer flood period,the contribution of glacier meltwater to Glacier No. 72 of Qingbingtan river basin was 74. 8%,and that of rainfall was 25. 2%,which meant that glacier meltwater was the main supplying water source of stream flow.
