| 摘 要： | 基于大兴安岭北部2004年和2005年的定位观测数据,对兴安落叶松林冠截留与降雨量及降水强度的关系进行了研究。结果表明:2004年兴安落叶松林冠的平均林冠截留率在生长季为18.61%,兴安落叶松林冠截留量随降雨量的增大而增加,但在开始降雨时递增的幅度不大。林冠截留与降水强度的关系也非常密切:降雨雨强越小,林冠截留量越大,林冠截留率越高。

| Abstract: | Through the located observation data from the north of Daxinganling mountain in the 2004 and 2005,the relationship between rainfall,rainfall intensity and interception by canopy of Larix gmelinii Rupr.Forest was studied.The result showed that the average intercept rate by canopy of Larix gmelinii Rupr.forest is between 18.61% in 2004.The intercepted rainfall by canopy was increased with total rainfall but lowly increased at the beginning of rainfall.The relationship between rainfall intensity and interception by canopy is also very osculation.The rainfall intensity diminishes with the increase of rainfall and interception by canopy. |
