中文摘要	基于黄土高原半干旱区2012-2013年观测数据,采用定位研究方法对该区油松人工林林冠层降水再分配情况进行研究;采用王彦辉模型和崔启武模型对林冠截留量进行模拟并对其适用性进行对比分析。结果表明:1)油松人工林穿透雨量与林外降雨量呈显著线性关系(R~2=0.978 9),林冠截留量与林外降雨量呈幂指数关系(R~2= 0.867 3),平均林冠截留率为25.5%;2)王彦辉模型和崔启武等模型模拟的决定系数R~2分别为0.724 5和0.755 4,黄土高原半干旱区油松人工林林冠截留模拟效果崔启武模型较王彦辉模型要好。
英文摘要	We investigated the rainfall redistribution of canopy on Pinus tabulaeformis plantations in the semi-arid areas of the Loess Plateau based on the data collected from 2012 to 2013 using the permanent plot method. The canopy interception was simulated separately by using Wang′s and Cui′s interception models, and the applicability of the two models were compared. The results showed that: 1) There was a linear relationship between rainfall and throughfall (R~2=0.978 9), but an exponential relationship between rainfall and canopy interception (R~2=0.867 3), and the average of interception rate was 25.5%. 2) The determination coefficient of Wang’s interception model was 0.724 5 and it was 0.755 4 for Cui′s. In general, Cui′s interception model was slightly better than Wang′s.
