【Abstract】 The glacierized area in the Altay Shan is at the highest latitude (45°47’-49°10’N) in China. In Chinese Altay, there are totally 416 glaciers with an area of 293.2 km2 and an estimated ice storage of 16.49 km3. The largest valley glacier is called Halasi glacier (5A255E21), 10.8 km long with an area of 30.13 km2 and its terminus descending to 2416 m. The Halasi glacier is characterized by plentiful accumulation in cold season, strong ablation in warm season, higher ice temperature in active layer, and large velocity of glacial movement, features different both from the maritime glaciers in southeast Xizang (Tibet) and from the extreme continental glaciers in Qilian Shan, but similar to the glaciers in western Tian Shan, which belong to the subcontinental type with dominant replenishment in cold season.更多还原
