The paper took Bahe Basin as research area and based on the actual data of the area from 1990 to 2010,and simulated runoff of the basin by MIKE SHE.It built the database of model by ArcGis technology and calibrated and validated the model parameters so as to evaluate the applicapility of the model by multi-object. The results showed that the simulation effect of annual runoff is good.The model has good adaptability in Bahe river basin.The calibrated parameters can provide reference for the further research of water resources utilization and management in the basin.
