| 摘 要： | 本文研究了7种不同森林类型林冠截留的月动态变化情况及林冠截留的水文生态效应。在一个观测期内林冠截留量随季节的变化而出现相应的变化，在雨季林冠截留量明显增大，7种不同森林类型林冠截留量的变幅从大到小的排序为：麻竹〉马占相思〉桉树〉勃氏甜龙竹〉混交林〉毛竹〉红竹。林冠截留量最大的是麻竹，最小的是毛竹，从大到小的排序为：麻竹（100．5ram）〉马占相思（62．4mm）〉勃氏甜龙竹（48．4ram）〉混交林（48．3mm）〉红竹（26．4mm）〉桉树（23．Omm）〉毛竹（10．1mm）。林冠截留率从大到小依次排序为麻竹（18．70％）〉马占相思（11．80％）〉桉树（8．56％）〉勃氏甜龙竹（8．41％）〉混交林（8．07％）〉毛竹（7．42％）〉红竹（4．10％）。结果表明：林冠层作为截留降水的第一作用层，对阻挡雨水侵蚀，减小雨滴的溅蚀，发挥了巨大的作用。

| Abstract: | This paper researches the monthly dynamic changes and the hydro-ecology effect of crown inception for the seven kinds of forest canopies.Crown interception storage has been changed correspondingly with season in one observation period,and it was increased obviously during raining season.The amplitude of crown interception storage of different forest canopy from the largest to the smallest is ordered as Dendrocalamus latifloeus>Acacia mangium De Willd> Eucalyptus wetarensis>Dendrocalamus brandisii>Mixed forest>Phyllostachys pubescens.>Phyllostachys iridescens.The crown inception of forest canopy with largest amplitude is Dendrocalamus latiflorus while the smallest is Phyllostachys pubescenI The amplitude of crown interception storage of different forest canopy from the largest to the smallest is ordered as Dendrocalamus latifloeus(100.5mm)>Acacia mangium De Willd(62.4mm)>Dendrocalamus brandisii(48.4mm)>Mixed forest(48.3mm)>Phyllostachys iridescens(26.4mm)>Eucalyptus wetarensis(23.0mm)>Phyllostachys pubescens.(10.1mm).The interception percentage of forest canopies from high to low in order are Dendrocalamus latiflorus(18.70%) >Acacia mangium De Willd.(11.80%)>Eucalyptus wetarensis(8.56%)>Dendrocalamus brandisii(8.41%)>Mixed forest(8.07%)>Phyllostachys pubescenI.(7.42%)>Phyllostachys iridescens(4.1%).The result shows that as the first function level of rainfall interception,the forest canopy plays an important role in preventing rainfall erosion and reducing splash erosion. |
