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.
According to the data of GPR and differential GPS in Qiangtang No. 1 glacier in Shuanghu area of central Qinghai-Tibet Plateau in 2011 and 2013, the influence of the size and change of glacier ice storage on the rivers and lakes and water is one of the most popular scientific issues. As a result, the horizontal and vertical thickness of glaciers in Qiangtang-1 are analyzed and discussed, and the contour of glacier thickness is drawn with the support of GIS technology to estimate the glacial reserves.The results show that the glacier of Qiangtang-1 is strongly affected , The cross section is typical “U” shaped development, the bottom is broad and flat.The vertical section rises slowly from bottom to top, the slope is small, the underlying terrain is flat, there is no obvious abrupt change, and has good consistency with the glacier surface The average glacier thickness is 51.28 m, the thickest is 132.15 m and the ice body reserves is 0.1236 km3.
