摘　　要：2007年春季对青藏高原南部的羊八井古仁河口冰川进行了探地雷达(GPR)的冰川测厚工作,获取了该冰川中轴线的厚度数据.基于羊八井古仁河口冰川的测量结果,对古仁河口冰川的体积进行了初步估算.结果表明:冰川的体积为0.0447 km3,并结合雷达图像分析了冰下地形和冰川槽谷形态;冰川槽谷呈V字形状,纵剖面由末端向上出现阶梯状起伏.In the spring of 2007, the depth of the Gurenhekou Glacier in the south of Tibetan Plateau was measured by using Ground Penetrating Radar （GPR）, and the depth profile along the longitudinal section of the Gurenhekou glacier was obtained. Based on the survey, it is found that the volume of the Gurenhekou Glacier is about 0. 045 km^3. With the map of GPR, the landform under the ice and the shape of the across section of the Gurenhekou Glacier are analyzed. In conclusion, the longitudinal-bed profile of the Gurenhekou Glacier comes up an undulate shape and the transverse- bed profile of it is a V-shape.
