以南方灵锐S82 GPS接收机为数据获取平台,借助RTK测量技术对均匀布设在祁连山老虎沟12号冰川表面的花杆网阵进行表面运动速度观测.2008年6—8月和2008—2009年整年的观测资料显示:2008—2009年间该条冰川表面流速最大值出现在海拔4 750~4 850 m,其中西支表面流速达到32.6 m.a-1,出现在海拔4830 m附近,东支表面流速达到32.4 m.a-1,出现在海拔4770 m附近.相比1959年的观测结果,该条冰川流速减慢了11%.
The data acquisition platform of South Sense Rui S82 GPS receiver was used to measure the surface movement velocity of the Arboreal array uniformly distributed on the surface of Glacier No 12 of Qilian Mountain by RTK measurement technique from June to August 2008 and from 2008 to 2009 The annual observation data show that the maximum surface velocity of the glacier appeared at an altitude of 4 750-4 850 m between 2008 and 2009, in which the surface velocity of the western branch reached 32.6 ma-1 and appeared at an elevation of 4830 m. The surface velocity Reached 32.4 ma-1 and appeared at an altitude of 4770 m, which was 11% slower than the 1959 observations.
