摘要
对青藏高原唐古拉山大、小冬克玛底冰川和昆仑山煤矿冰川的观测研究表明，１９９２／１９９３年冰川的物质平衡均为正平衡，其平衡值唐古拉山冰川大于昆仑山冰川。冰川物质平衡过程存在四个阶段，即低水平维持阶段、强积累弱消融阶段、强消融阶段和较强积累弱消融阶段。空间上反映出随海拔升高波动增大的趋势。
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.
