摘要：

Rainfall interception losses from an agroforestry system in semi-arid Kenya comprising Grevillea robusta and maize were measured over a period of 33 months. These measurements showed that interception was slightly higher (10.2%) under trees with no maize understorey, than in the intercropped treatment (9.8%), and was directly related to the degree of tree canopy cover. Interception estimates using the reformulated version of the Gash analytical model were similar to 4% lower than measured totals, and were strongly dependent on both canopy cover and on monthly variations in the mean rainfall rate ((R) over bar, mm h(-1)).
