| 摘 要： | 对冀北山地落叶松桦木混交林、山杨桦木混交林、油松蒙古栎混交林3种典型林分林冠层降水分配进行了研究。结果表明：在观测期间,随着降雨量的增加,穿透雨量、径流量和林冠截留量都增加,林冠截留率降低;3种林分穿透雨量分别为115.31,115.08,125.94mm,分别占林外降雨总量的68.94%,68.81%,75.31%;3种林分单株树干径流量分别为4.35,5.90,6.24mm,分别占降雨总量的2.56%,3.47%,3.67%;可用线性回归方程来分别拟合穿透雨、树干径流、林冠截留量与林外降雨间的关系,均取得较好结果。引用林冠截留概念模型,能够较好地预测冀北山地森林生态系统降雨的林冠截留特征。

| Abstract: | Study on the precipitation distribution laws of 3 forests of the mixed forest of Larix and Betula,the mixed forest of Populus and Betula,the mixed forest of Pinus and Mongolicain in North Mountain of Hebei Province.The results indicated that: during the period of observation,along with the increase of rainfall,the throughfall,stemflow and crown interception increase,but the crown interception rate decreases;throughfall of 3 forest stands were 115.31 mm,115.08 mm,125.94 mm,accounting for 68.94%,68.81%,75.31%... |
