本数据集是2015年8月及2016年8月对冰川表面的运动点进行了冰川表面运动的观测，观测是使用RTK-GPS进行测量的。1号冰川年运动速度；1号冰川东、西支冰舌的年进退变化量；年度的各流速点的空间坐标<，中国天山乌鲁木齐河源1号冰川物质平衡项目的观测研究始于1959年夏季，当时的1号冰川面积为1.95 km2，冰川长度为2.41 km，冰川末端最低为海拔3736 m，是乌鲁木齐河流域发育规模最大的双冰斗冰川形态的现代冰川。随着冰舌萎缩，1993年，1条冰川蜕变为两条完全独立的冰川体系，即1号冰川西支和1号冰川东支。由此也表明一个区域冰川退缩意味着该区域冰川数量可能是增加的，而冰川面积及其储量是递减的。

At that time, the area of Glacier No.1 was 1.95 km2, the length of glacier was 2.41 km, and the lowest end of glacier was 3736 above sea level m. It is the largest modern glacier in the form of double cirque glacier in Urumqi River Basin. In 1993, a glacier degenerated into two completely independent glacier systems, namely, the West Branch of Glacier No. 1 and the Eastern Branch of Glacier No. 1. It also indicates that the glacier retreat in a region means that the number of glaciers in the region may increase, while the area and reserves of glaciers are decreasing.
