锐齿栎林林冠截留与大气降水关系

对锐齿栎林和灌丛林外降水、穿透降水、干流的测定研究表明:间伐林、未作业林、灌丛穿透降水率分别为91％、80％、87％;林冠截留率分别为7％、14％、13％;前两个林分干流率分别为2％、6％。并建立了各参数具有实际水文学意义的林冠截留、林内降水与大气降水的预测模型。

Relationship Between Forest Canopy Interception and Rainfall of Sharptooth Oak Forest

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.
