摘要
亚洲大陆性气候区的附加冰的补给作用,随地形条件和积消特征而差别很大;冰体厚度深受冰床地形影响;冰面消融状况主要决定于小气候特征,并出现不吻合于大区域气候的现象;冰川温度依赖于冰面融水量及渗入特征;地形条件对冰川的稳定性影响甚大,并形成地形型稳定性冰川。
The area of the superimposed ice zone of Heigou glacier No.8 is up to 28.9% of the total. The superimposed ice is important supply to Heigou glacier No.8. The maximum thickness of the glacier is 192 m owing to the influence of the glacier bed topography. The glacier profits from local heating of local climate and there is a great meltwarter from glacier surface in firn basin. The meltwarter infiltrates into the firn and the crevasses and brings about that the ice temperature of Heigou glacier No.8 is higher than the others. The glacier variation is less than some glaciers in Tianshan and it is clear that the glacial stability is bigger.
