以天山乌鲁木齐河源1号冰川1996/1997年度和1997/1998年度实测物质平衡资料为基 础,利用等直线法计算出1号冰川年物质平衡分别为口-853.0mm和-789.9mm,相应的AAR值分别 为0.25和0.33.自1959以来,1996/1997年度1号冰川物质负平衡值最大,1997/1998年度次 之.根据该地区气温和降水记录资料分析,造成这种结果的主导因素是气温,尤其是夏季消融期气 温,其次是降水.

Based on the observation in 1996 / 1997 and 1997/1998, mass balances of the Glacier No.1 at the Headwaters of the Urumqi River were calculated as -853.0 mm and -789.9 mm. Since 1959, the negative value of mass balance in 1996/1997 has been the maximum, next to that in 1997/ 1998. By analyzing air temperature and precipitation in the region, it is found that the main factor resulting in this phenome- non is abnormal temperature, especially the abnormal summer temperature.
