Tang Zhen (Dept. of Forest Resource Protection, NWFC, 712100)
Describes the rainfall above forest canopy, rainfall through forest canopy and stem flow of sharp-tooth oak ( Quercus aliena var. acuteserrata Maxim. ) forest and rainfall in shrubbery. In intermediate cutted forest, reserved forest and the shrubbery, the rate of rainfall through forest canopy is 91%, 80%, 87% and the rate of forest canopy interception is 7%, 14%, 13% respectively. In the first two forests, the rate of stem flow is 2% and 6% respectively. The forcast models of forest canopy interception, rainfall under tree crown and open air rainfall have also been established according to parameters with practical hydrological meanings.
