摘要/Abstract

摘要： 冰川冰贮量的大小与变化对河流与湖泊水的影响是当前关注的热点科学问题之一. 根据青藏高原中部双湖地区羌塘1号冰川2011、2013年探地雷达测量数据和差分GPS定位结果，分析探讨了羌塘1号冰川横、纵剖面厚度特征，并在GIS技术的支持下，绘制了冰川厚度等值线，对冰川储量进行了估算. 结果表明：羌塘1号冰川作用强烈，横剖面呈典型的“U”形发育，底部宽阔平坦. 纵剖面从下往上缓慢抬升，坡度较小，下伏地形平坦，无明显突兀变化，与冰川表面具有很好的一致性. 经计算整条冰川平均厚度51.28 m，最厚处132.15 m，冰体储量0.1236 km³.

Abstract: Glacier, named solid reservoir, is an important water resource. Glacier change and its impact on rivers and lakes is one of the hot scientific issues of current concern. Based on the GPR sounding on the Qiangtang Glacier No.1 in Shuanghu of the Tibetan Plateau in 2011 and 2013 and the differential GPS positioning results, in this paper, the features and the depths of underlain terrain are analyzed and discussed. A contour map of glacier thickness is drawn and the glacier reserve is estimated under the support of GIS technology. It is found that the effect of the Qiangtang Glacier No.1 is very strong: its cross-section develops a typical "U" shape with a wider bottom; its longitudinal profile changes slowly with a small slope and the underlain terrain shows a good agreement with glacier surface without significant incongruity. The average thickness of the glacier is 51.28 m, with the maximum thickness of 132.15 m and ice storage of 0.1236 km³.

Key words: ice-thickness, ice volume, GPR, Qiangtang Glacier No.1
