Abstract

Abstract: In this article, as examples of the Kangwure Glacier,the Gurenhekou Glacier,the Urumqi Glacier No.1 and the East Rongbuk Glacier,average thickness value of the every glacier mainstream line calculated by the theory of the SIA,DEM data and the glacier vector data,andevery ice volume is obtained by interpolation method.The results firstly show that the volume of the Kangwure Glacier,the Gurenhekou Glacier, the Urumqi Glacier No.1 and the East Rongbuk Glacier are about 0.022、0.026、0.024 and 1.450 km³.Furthermore, the ice volume based on the theory of the SIA are smaller which may relate to the precision of DEM data and sections division, compared with the ice volume based on the traditional empirical equations and GPR measured data.

Key words: theory of the SIA, glacier vector data, thickness of the glacier, ice volume, the mainstream line of the glacier
