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115.31，115.08，125.94 mm，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4.35，5.90，6.24 mm，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% of total rainfall; stemflows of 3 forest stand were 4.35 mm, 5.90 mm, 6.24 mm, accounting for 2.56%, 3.47%, 3.67% of total rainfall. The relationships among throughfall, stemflow, crown interception and total rainfall could be described significantly by a linear function. This article refers to interception conception model directly, which can effectively predict the interception capability of the forest ecosystem in North Mountain of Hebei Province.
