本数据集为天山乌鲁木齐河源1号冰川1985-1999年冰川运动速度。1号冰川表面运动速度是用精密光学经纬仪及全站仪进行测量的，前者，从冰川上的控制点对布设在冰内的花杆进行重复前方交会，以坐标法计算，求出花杆（冰体）在单位时间内的空间位移而得到的。每年消融开始5月和消融结束的8月底各观测一次，这样便可得到消融期及全年的流速资料。后者，对冰川表面运动速度的观测是使用全站仪进行测量的，从控制点K1、K2上对布设在冰川表面的测杆进行观测的，以座标法计算出冰体单位时间内的空间位移。该数据集主要是记录了冰川运动速度（夏季、冬季和年运动速度）。

Observations are made once a year in May at the beginning of the ablation and once a year at the end of August at the end of the ablation, so that flow velocity information can be obtained for the ablation period and for the whole year. In the latter case, the observation of the speed of movement on the glacier surface is measured using a total station, and the spatial displacement of the ice body per unit of time is calculated by the coordinate method from the control points K1 and K2 on the measuring rods laid on the glacier surface. This dataset is primarily a record of glacier movement velocities (summer, winter and annual velocities).
