Abstract: The stemflow process is measured by experimental test method. Its curve is quite similar with that of R-L-Ccircuit intantaneous state. Because of the resemblance, the latter is used for fitting curves of stemflow process, and the analytic solution is obtained. The parameter values are debugged on the computer,and the significance of hydrology is also discussed. The relationship between parameters and factors influencing stemflow process is qualitatively analysed, and the simulating results are satisfactory.

Key words: Stemflow process, Experimental test method, Model of instantaneous state
