中文摘要：
2006年夏季祁连山七一冰川野外观测资料表明：夏季晴天冰川消融区上的气温日变化过程存在滞后于消融强度日变化过程的现象，最大值相位差约4h。辐射平衡在消融热量总收入中权重最大，控制着消融强度的日变化过程；同时，冰川区气温则受到局地环流的强烈影响，消融区空气同周围非冰川区上的暖气流进行的水平热交换以及下垫面性状共同决定了消融区气温的日变化。
英文摘要：
Surface ablation and meteorological factors had Been monitored on the Qiyi Glacier in 2006. The results show that the daily variation of air temperature lags behind the ablation intensity in the fair weather of warm season and the phase difference between the two maximum values is about 4h. By summarizing and analyzing the field data, the viewpoint is taken shape that the net radiation is a large proportion of the heat for ablation and ablation intensity does not coincide with air temperature, which is determined by the variation of net radiation. Local circulation influences intensively the air temperature of the glacierized region, and horizontal heat exchange between glacierized area and non-glacierized area and properties of underlying surface of the glacierized region determine the air temperature over the ablation area.
