| 摘 要： | 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－８５３．０ｍｍ和－７８０．９ｍｍ，相庆的ＡＡＲ植分别为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 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

| Abstract: | 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. |
