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。\n1号冰川东支单点物质平衡、1号冰川西支单点物质平衡、1号冰川冬平衡、1号冰川年物质平衡、1号冰川东支年度各高度带冰川面积及其物质平衡、1号冰川西支年度各高度带冰川面积及其物质平衡。

Generally, 3 measuring rods are arranged at equal distance on the ice surface of each cross section to observe the accumulation and dissipation during the melting period, and the data of the accumulation area is obtained by digging snow pits get. The observation method is the same as that at the end of April / September of this year. Glacier No.1 has disintegrated into two independent branches, the East and the West.

It was the largest modern glacier with double bucket glacier form 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.\nThe single point material balance of the East Branch of glacier 1, the single point material balance of the West Branch of glacier 1, the winter balance of glacier 1, the annual material balance of glacier 1, the annual glacier area and material balance of each altitude zone in the East Branch of glacier 1, and the glacier area and material balance of each altitude zone in the Western Branch of glacier 1.
