The Application of GPS in Glacier Flow Velocity: A Case Study of Qiyi Glacier
Surface flow velocity is a key parameter of glacier kinetic theories study. With the help of GPS, glacier surface flow velocity research improved convenient and accurate. Therefore, this paper is committed to acquire the condition of surface flow velocity of Qiyi Glacier during 2009 to 2010 based on GPS data, optical remote sensing images and topographic maps. And it is concluded that during this time, the average surface flow velocity of Qiyi Glacier is decreasing while distributed relatively fast on central and slowly on both sides, and area retreated about 0.06km2 compared with that of 1965, whose value is consistent with motion mode of mountain glacier and the tendency of changes in Qiyi Glacier according to ELA data and Mass balance.
