摘要

The original Gash analytical model and the sparse Gash's model were combinedto simulate rainfall interception losses from the top- and sub-canopy layersin Shaoshan evergreen forest located in central-south China in 2003. Thetotal estimated interception loss from the two canopy layers was 334.1 mmwith an overestimation of 39.8 mm or 13.5% of the total measuredinterception (294.3 mm). The simulated interception losses of the top- andsub-canopy suggested that the simulated interception losses in the stages of''during storms'' and ''after storms'' were in good agreement with the publishedones. Both the original Gash model and the sparse model overestimated theinterception losses, but the sparse model gave more accurate estimates thanthe original Gash model.
