摘要：

Gash's analytical model of rainfall interception is reformulated, with improved boundary conditions, to give a better description of the evaporation from sparse forest. The model is tested against data from Les Landes Forest collected during HAPEX-MOBILHY. The new formulation requires an estimate of the evaporation per unit area of canopy, rather than per unit ground area. When the evaporation per unit area of canopy is equated with the estimates of evaporation derived from the Penman-Monteith equation there is an improved description of the observations.
