| 摘 要： | 通过对贡嘎山亚高山峨眉冷杉与冬瓜杨演替林连续两年林下降水与树干径流的实验观测,分析研究了演替林林下降水、树干径流、林冠截留的变化特征,并验证了Gash(1995)模型模拟该区林冠截留的适用性.结果显示,2008年和2009年贡嘎山亚高山演替林林下降水分别占降水量的76.4%和77.0%,树干径流量较小,可以忽略不计,林...

| Abstract: | Gross rainfall,throughfall and stemflow were measured during the growing seasons of two tree species of Abies afbri and Populus purdomii in 2008 and 2009 in a subalpine succession forest on the Gongga Mountain.Throughfall(the net precipitation under the two tree species),steamflow and canopy interception are analyzed.In addition,the applicability of the Gash model(1995) is examined using the measurement.The model requires only a limited amount input and uses the Penman-Monteith equation for evapotranspirati... |
