摘    要:采用改进的双层积雪模型,以澜沧江上游积雪区为例进行了模型的应用,并从模型原理、模型适用条件、模拟效果等方面与传统的度日模型进行了对比分析。结果表明:以能量平衡和质量平衡为基础的双层积雪模型,在融雪物理机制上更加完善;模型不仅能模拟积雪区融雪产流量,还能模拟融雪过程中冠层对降雪的截留量、蒸发中的汽化和升华损失量、冠层对地面的二次降水量、积雪层中融雪水再结冰量等各个子物理过程;通过对双层积雪模型的改进,使融雪产流模拟结果更符合实际情况,可为寒区冰雪水文过程的研究提供借鉴。

关 键 词:改进的双层积雪模型  度日模型  澜沧江上游积雪区

Abstract:This paper describes the use of improved double-layer snow-melting model on snowpack of upper Lancang River,and a comparative analysis is made of the degree-day model on model,the applicability of the model and simulation results.The results show that the double-layer snow-melting model based on energy balance and mass balance is more reasonable in snowmelt mechanism.The model can not only simulate the runoff yield of the snowmelt,but also the sub-processes such as snow interception and twice precipitation ...
Keywords:improved double-layer snow-melting model  degree-day model  snowpack of the upper Lancang River
