冰川表面的能量平衡对于了解气候变化对冰川的影响非常重要。利用点尺度能量平衡模式，分析了祁连山八一冰帽冰川表面能量通量沿着分布特征及其对冰川融化的贡献。位于冰川上的自动气象站（AWS）的半小时气象数据被用来驱动能量平衡模型。模型模拟结果能较好地反映2016年夏季气象站附近的质量平衡观测结果。结果表明，净辐射（86%）在地表能量平衡中起重要作用，湍流热通量（14%）对能量平衡的贡献相对较小。与中国其他大陆冰川相比，（老虎沟12号冰川和七一冰川），是由于八一冰帽在8月份存在一个持续的正湍流潜通量期，导致8月份融化速度加快。我们的研究还提出了在融化季节开始时，频繁的夏季降雪通过改变地表温度来减缓地表融化的效果。
Energy balance at the glacier surface is important for understanding the impacts of climate change on glaciers. Here, we analyzed the characteristics of the glacier surface energy fluxes along with their contributions to glacier melt on Bayi Ice Cap in Qilian Mountains by using a point-scale energy balance model. The half-hourly meteorological data from an automatic weather station (AWS) located on the glacier was used to drive the energy balance model. The model simulated results could accurately represent the mass-balance observations from the stake near the weather station during summer 2016. Our results showed the net radiation (86%) played an important role in the surface energy balance, and the contribution of the turbulent heat fluxes (14%) to the energy budget was relatively less important. A distinct behavior of energy balance, as compared to other continental glaciers in China (e.g., two adjacent glaciers Laohugou No. 12 Glacier and Qiyi Glacier), is the fact that a sustained period of positive turbulent latent flux exists on Bayi Ice Cap during August, causing faster melt rate in the month of August. Our study also presented the effect of frequent summer snowfall in slowing down surface melt by changing the surface albedo during the beginning of the melting season.
