Abstract：Based on the hydrological data during 1980-1989 year in Luanxian hydrological station ,the vertical mixed run?off model and VIC model were selected to compare the simulation accuracy in Luanhe River Basin. On the basis of runoff simulation results,the effects of different evaporation inputs and different calculation step on runoff simulation were stud?ied. The results show that:comparing to the VIC model,the vertical mixed runoff model was more suitable for runoff simu?lation in Luanhe river basin,the relative error is less and the certainty factor is higher than VIC model;the runoff simula?tion results of 0.5 h step were better than 1h step,regardless of the runoff peak or the process of the flood;the evaporation that was calculated by penman-Monteith method can be as the evaporation input for the hydrological model in Luanhe Riv?er Basin,which has a better simulated result than the observed evaporation data. The outputs can provide a valuable refer?ence for the study of hydrological modeling and runoff simulation in Luanhe River Basin.
