%X The observation and Study on the material balance project of Glacier No.1 at the source of Urumqi River in Tianshan Mountains of China started in the summer of 1959. 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 m above sea level. 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.The 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.
