英文摘要	Subsurface flow plays an important role in forest catchment hydrological processes, for which a modified model is established in this paper. Firstly, by taking soil samples from Natural Preserve Forests of Changbai Mountain, two crucial parameters for subsurface flow, the saturated hydraulic conductivity, and effective porosity, were measured in the laboratory. Secondly, submodels of the two parameters varying logarithmically with soil depth were established through regressive analysis. Then a modified subsurface stormflow model (Modified model) was founded by substituting the submodels into a storage-discharge model (Sloan's model), established by Sloan in 1983. Finally, to verify the Modified model, five rainfall events on a simulated hillside were carried out. The subsurface flow processes were simulated using the Modified model, Sloan's model and Robinson's model. The comparison of simulated subsurface stormflow processes using the three models respectively with measured ones showed that the Modified model obtained better accuracy for peak flow and total amount of subsurface stormflow than the other two models.
