分布式融雪径流模型研究进展

Research Progress of Distributed Snowmelt Runoff Model

融雪径流在寒区、干旱区对当地的水资源起着十分重要的作用,但融雪同样也会带来融雪性洪水、山体滑坡等自然灾害,因此对融雪径流的模拟一直是寒旱区的重要热点,针对近些年来融雪径流模拟研究的发展趋势,介绍融雪径流模拟的主要类型,一类是基于能量平衡的物理模型,另一类是基于气温指标的度日模型。重点阐述分布式融雪径流模型的应用情况及其进展,并对分布式融雪径流模型进行讨论与展望。

Snowmelt runoff plays an important role in local water resources in cold and arid areas,but snowmelt will also bring many natural disasters.Therefore,the simulation of snowmelt runoff has always been an important hotspot in cold and arid areas.In this paper,the development trend of snowmelt runoff simulation in recent years is introduced.The main types of snowmelt runoff simulation are introduced.One is the physical model based on energy balance,and the other is the degree-day model based on temperature index.It focuses on the application and progress of the distributed snowmelt runoff model,and discusses and prospects the distributed snowmelt model.
