摘要/Abstract

摘要： 冰川地形是构建冰川流动模型的基础,对于认识冰川响应气候变化的动力机制具有重要意义.在2009年和2014年消融季,使用探地雷达对祁连山老虎沟12号冰川进行了厚度测量和冰下地形观测,获得了沿冰川中流线和多条横剖面的厚度资料,并对中流线上的厚度分布特征和槽谷形态进行了研究.研究结果表明,东、西支冰川的平均厚度分别为190m和150m,东支冰川冰下地形起伏大于西支,支冰川的表面坡度都较缓和.东、西支冰川进入汇合区时厚度分别为122m和157m,由于支冰川的横向挤压和汇流,汇合区中部冰川厚度增加到162m.冰川槽谷形态具有空间差异,东、西支冰川槽谷形态近似于对称的V型,但是在冰川汇合区,槽谷底部变宽,边坡变缓,发育有不对称槽谷.

Abstract: The bed elevation and ice depth of a mountain glacier are important boundary conditions for numerical ice flow modelling, which can be used to project future glacier evolution under a changing climate. In the ablation seasons of 2009 and 2014, ground-penetrating radar sound was carried out on the Laohugou Glacier No.12, Qilian Mountains. The glacier depth and bed topography along the centerlines and glacier cross-sections were obtained. The characteristics of ice depth change along the centerlines were studied and the shapes of cross-section profiles were quantitatively analyzed. The sound results show that the average ice depths along the centerlines of the eastern tributary (ET) and the western tributary (WT) were about 190 m and 150 m, respectively. The ET's bed topography was in general more rugged than that of WT, while surface slopes of both tributaries were gentle. When tributaries entered the confluence area, the ice depths of ET and WT were 122 m and 157 m, respectively. Due to transverse compression and convergence from the two tributaries, the ice depth increased to 162 m at the center of the confluence area. The form of glacial valley had spatial variation and were in general closer to V-shape. However, the valley of the confluence area had widened, and the glacial troughs developed more asymmetric.

Key words: Laohugou Glacier No.12, ground-penetrating radar, glacial trough, bed topography
