Shule river is a typical continental river in arid zone of northwest, its ice and snow melt water is one of the important sources of spring runoff supply. Based on MOD10A2 of MODIS snow products, DEM data and meteorological data, this paper constructed SRM model in the upstream of Shule river basin, the coefficient R2 of determination is 0.834, and the volume difference DV is 1.63%. The results show that this model can basically reflect the trend of snowmelt runoff in Shule river basin and achieve better simulation effect.It can be used to predict spring runoff in this basin and provide the basis for the prevention of spring snowmelt flood disaster and the reduction of spring drought.
