摘　　要：探地雷达是一种利用电磁波的反射原理探测地下介质分布特征的地球物理勘探技术 ,在冰川研究中发挥了重要作用。在天山一号冰川上用探地雷达进行了探测 ,获得了能够清晰地分辨冰 -岩界面的雷达剖面。根据这些雷达剖面读出冰厚值 ,再结合最新的冰川地形图 ,作出了天山一号冰川的冰厚等值线图和冰下地形图 ;Ground Penetrating Radar(GPR) is a electromagnetic geophysical technique for subsurface exploration. It is widely used in glaciology. we have employed GPR to detect Tianshan No. 1 Glacier and obtained some profiles which could clearly show the interface between ice and rock. From these GPR profiles, we have read the ice thickness, and made the ice thickness isopach map of No.1 Glacier and the contour map of subice topography on No.1 Glacier. Finally, we have calculated its ice reserves.
