摘要:

以陕北黄土丘陵沟壑区燕沟流域为试验区,以人工刺槐林为研究对象,根据42场降雨观测资料,用PenmanMonteith修正公式计算试验地刺槐林冠的附加截留量,建立适合于黄土丘陵沟壑区的附加截留计算公式,修正和对比了崔启武和王彦辉的模型。修正后的模型克服了原模型中处理附加截留的不足,使模拟精度明显提高,能更客观地反映林冠截留降雨的实际情况。

Abstract:

In Yangou watershed of the loess region in northern of Shaanxi Province,based on outdoor experimental data of 42 rainfalls in Black Locust woodlands,adjunctive interception was calculated by PenmanMonteith equation and the formula to calculate adjunctive interception quantity was established,which is adapted to the hilly and gully region of northern of Shaanxi Province. Cui Qiwu and Wang Yanhui models were revised so as to improve markedly their precision and reflect better the practical situation of rain interception by canopy. 

Key words: canopy interception quantity, simulation, Black Locust (Robinia pseudoacacia), loess hilly and gully region
