Abstract Based on the observation in 1992/1993, mass balance of Da Dongkemadi glacier and Xiao Dongkemadi glacier in the Tanggula Mountains and Meikuang glacier in the Kunlun Mountuins were calculated. It was found that mass balances of these glaciers were all positive, 289.7mm, 211.4mm and 95.7mm respectively, with an obvious regional difference in mass balance, i.e., mass balance of the glaciers in the Tanggula Mountains in the central part of Tibetan Plateau was larger than that in the Kunlun Mountains in the margin of the plateau. Owing to the effect of seasonal climatic variation on the mass exchange of these glaciers, the processe of mass balance in an year have four stages, two intensive accumulation periods in the begainning and the end of warm season, an intensive ablation period in the warm season, and a period lasting about 8 months(which span over the cold season)with fluctuations of mass balance in a low level. Different from glaciers in other mountains, mass balance of these glaciers undulatingly increases with height.
