【摘要】 1998～ 1999年实测了河南境内长江中游栓皮栎林的林外降水、林内降水、树干径流以及下层植被和枯落物对降水的影响 ,并建立了相关的计算模型。结果表明 :观测期内栓皮栎林冠层能截留降水 2 0 .77% ,并将 4.85 %的降水转化为树干径流 ,枯落物的最大持水量为 13.40 t/ hm2 ,林外降水和林内降水、树干径流之间为线性关系 ,而林冠截留符合灰色模型更多还原

【Abstract】 The precipitation in the outside and the inside of the forest (Quercus variabilis), the stemflow and the lower vegetation interception were measured in Guangou watershed in Henan province from 1998 to 1999, and the calculation models were built. The results showed that the canopy precipitation interception and stemflow of forest were 20.77% and 4.85% respectively, the maximum water holding capability of litters was 13.40 t/hm 2, the linear relationship between precipitation in the outside and the inside of the forest as well as stemflow was showed, while canopy precipitation interception model conformed to the gray Verhulst model.更多还原
