Abstract: In this study,the MODIS snow cover data and the measured meteorological and hydrological data in the upper reaches of the Xilin River Basin in snow melt period (from March to May) of 2014-2016 were simulated by WinSRM1.10.The purposes of the study were to verify the applicability of a snowmelt runoff model (SRM) in the drainage basins in arid and alpine steppe based on the description of the model structure and the meaning of the parameters,and to reveal the proportion of spring snowmelt volume in annual runoff volume in the upper reaches of the Xilin River Basin from 2014 to 2016.The results showed that the SRM could be used to ideally reflect the change trend of spring snowmelt volume in the study area,and to predict the time of flood peak of spring snowmelt.The accuracy of the model was evaluated,and the fit goodness coefficient (R2) and volume difference (DV) of the 3-year simulated values were obtained,which were superior to the mean values published by the World Meteorological Organization.Therefore,the SRM has a good applicability in the upper reaches of the Xilin River Basin,and it is of great significance for the rational use of ice-snow resources in grasslands.
