Thank you very much for your reply.
 
I’m using station data for climate, so I think the meterological data should be free of major erorrs.
 
I modified soil parameters such as lateral conductivity and field capacity according to your suggestions, and the accuracy of the model was indeed improved. But the results of simulation still could not capture the peak of runoff well.
 
The observation runoff fluctuated a lot and had a large range of changes, while the simulation runoff had fewer fluctuations and a small range of changes.
 
The simulation runoff fit well with the trend of precipitation data, but not well with the observation runoff, especially in August.

I have certainly seen much worse results than that! I would start with 
your climate forcings and soil parameter values. Are you using station 
data for climate?
