Abstract: Glacier is an important surface water resources in Northwest China. However, due to lack of measured glacier ice thickness data, the ice reserve estimation of glacier has varying degree of indeterminacy. In May of 2015, ice thickness of the Meikuang Glacier on the Eastern Kunlun Mountains was sounded by a pulse EKKO PRO Ground Penetrating Radar system (with a 100 MHz antenna), with five short transversal profiles and one long longitudinal profile. Based on the GPR data, GPS position of the sounding point, SRTM DEM data (30 meters) and Landsat8 OLI image in 2015, the Meikuang Glacier was seperated a sounded area from the whole glacier field. Ice thickness contour map was drawn by Ordinary Kriging method and ice reserve was calculated by integration of thickness and boundary distribution data under the support of GIS technology. The sounding showed that the maximum thickness was 87 meters at 4 952 meters elevation, near to the main flow line. It was found that in 2015 the glacierized area, average thickness and total ice reserve of the glacier was 0.95 km2, 25.77 meters and 0.0242 km3, respectively. Based on raster map of the glacier surface and ice thickness, the topography of glacier bed was obtained. The results show that the glacier is wide in the upper part and narrow along the valley, and the glacier bed is complex. In the area with larger thickness, the topography has near V-shape, showing the morphological characteristics of cirque glacier.
