中文摘要	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4 830 m附近, 东支表面流速达到32.4 m·a~(-1), 出现在海拔4 770 m附近.相比1959年的观测结果, 该条冰川流速减慢了11%.
英文摘要	The Laohugou Glacier No.12 is the largest valley glacier in the Qilian Mountains, located in northern Tibetan Plateau. Movement is the basic characteristics of glaciers and an important symbol different from other natural ice. Glacier change not only reflects the climate change, but also has important significance to humanity society. In the arid regions of West China, glaciers become the important water resources. GPS receivers (South-Lingrui S82 type) as data catching platform were used to survey the surface velocities of the Laohugou Glacier No. 12 through RTK measurement. It is found that the maximum velocity appeared at the altitude of 4 750~4 850 m during the period of 2008--2009, when in the west branch the maximum surface velocity reached 32.6 m·a~(-1), appeared at the altitude near 4 830 m, and in the east branch the maximum surface velocity reached 32. 4 m·a~(-1), appeared at the altitude near 4 770 m. The glacier velocity slowed down about 11% as compared with the surveying in 1959.
