This paper introduced Variable Infiltration Capacity Land Surface Hydrological Model from the interdisciplinary aspect of hydrology and meteorology.The model was applied into Bailian River Basin of Hubei Province to discuss its adaptability in flow simulation of the medium or small basin.Combined with DEM,vegetation and soil data,through model pre-processing,the framework of VIC model for the Bailian River Basin was established.The sensitivity of model parameters was made at last.The results showed that the model can reflect the daily flow hydrological process of the basin on the whole and can be adaptable for the basin.
