摘要:
为了探究落叶松林对降雨再分配的过程，通过对木兰围场国有林场管理局北沟林场内落叶松林进行穿透降雨、冠层截留和树干径流3个方面进行了监测，结果表明：（1）穿透雨量和林冠截留占林外降雨量的比例比较大，树干径流量的比例则非常小，分别为59.44%，39.20%，1.36%；（2）穿透雨量和林外降雨呈现线性关系（R2=0.988 6），林冠截留量与林外降雨量也具有明显的幂函数关系（R2=0.755 9），树干径流与林外降雨量具有明显的线性相关关系（R2=0.755 9），并且都达到了极显著水平（p < 0.01）；（3）根据穿透雨与林外降雨的方程，当林外降雨量高于1.81 mm时会产生穿透雨。依据林外降雨与树干径流的方程，当林外降雨高于5.18 mm时会产生树干径流。林冠在降雨再分配过程中起到了很重要的作用，形成了二次降雨。
Abstract:
In order to explore the process of Larix principis-rupprechtii Mayr forest on rainfall redistribution, throughfall, canopy interception and stem flow were monitored in Larix principis-rupprechtii Mayr forests of the north valley in Mulan-Weichang Forestry Management Bureau. The results showed that: (1) throughfall and interception ratio of rainfall outside of forest volume were larger, the trunk runoff proportion was very little, which was 59.44%, 39.20%, 1.36%, respectively; (2) throughfall and rainfall appeared to be a linear relationship (R2=0.988 6), the canopy interception and rainfall outside the forest also had the obvious power function relationship (R2=0.755 9), trunk diameter flow had remarkable linear relation with the rainfall outside the forest (R2=0.755 9) at the extremely significant level (p < 0.01); (3) according to the equation on the throughfall and the rain outside of forest, when the rainfall was higher than 1.81 mm outside the forest, the throughfall would occur, based on the equation on rainfall outside the forest and tree trunk runoff, the trunk runoff would produce when rain outside the forest was greater than 5.18 mm. Canopy played a very important role in the redistribution of rainfall, the formation of a secondary rain.
