摘要
以天山乌鲁木齐河源１号冰川１ ９９６／ 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－７８９．９ ｍｍ，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 ürümqi 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 phenomenon is abnormal temperature, especially the abnormal summer temperature.
