摘　　要：根据林冠截留降雨的物理现象,借鉴流域蓄满产流理论建立了一个林冠截留降雨新模型。结合两片林分的实测资料,介绍了该模型参数的确定方法,并且对模型进行了有效性验证。结果表明:计算值与观测值吻合,表明该模型可揭示林冠截留降雨的基本特征,如果已知模型参数,可以用于林冠截留降雨的预测计算。In order to study the interception law of forest canopy to precipitation, based on the theory of stored-full runoff in watershed, a new model of precipitation interception was developed from mechanism of forest canopy intercepting rainfall. The determining method of model parameters was produced by combining with observation data of two woodlands. The effectiveness of the model was also examined. The results showed that calculation values well fit observation values well. Therefore, the model revealed a general law and characteristics of forest canopy interception to rainfall. This model could be applied to forecast calcula- tion of interception when model parameters are given.
