The changes of ice volume are closely related to the changes of glacial water resources and the contribution of melt water to the river runoff. Based on the ice thickness measured data, topographic maps and the long-term field observation data, this study has calculated the ice volume of Urumqi Glacier No.1 in different periods using GIS technique and analyzed the characteristics of their changes. Results indicated that the ice volume of Urumqi Glacier No.1 is 10736.7×104 m3, 10296.2×104 m3, 9989.4×104 m3, 8797.9×104 m3 and 8115.0×104 m3 in 1962, 1981, 1986, 2001 and 2006, respectively. During 1962-2006, the total ice volume of the glacier has reduced by 24.4% and the reduction rate of ice thickness, area and maximum length is 12.1%, 14.0% and 7.6%, respectively. The glacier was in a state of rapid shrinking with an accelerated tendency against the background of climatic warming in the past several decades. Before 1981, area shrinkage and terminus retreat was the key cause of the ice volume reduction; during 1981－2001, the reduction of ice volume was caused by three aspects: ice thickness, area and length, and area shrinkage was considered as the main factor; the noticeable reduction in ice volume is due to the intensive thinning of the ice thickness after 2001.
