| 摘 要： | 为探究北京山区主要人工林枯落物水文效应,以北京市怀柔区汤河口镇庄户沟小流域油松、刺槐、侧柏3种林分为研究对象,利用枯落物现存量样地调查、浸泡实验和抗冲槽法,建立枯落物持水量、吸水速率和浸水时间相关关系,定量研究枯落物层水文效应,结果表明:1)3种林分枯落物现存量和总厚度表现为油松最大,分别为6.37t/hm2和4.0c...

| Abstract: | The hydrological effects of forest litters in Pinus tabulaeformis,Robinia pseudoacacia,and Platycladus orientalis forest communities in Zhuanghugou watershed,located in Tanghekou Town,Huairou District of Beijing,were studied in this article.Results show that: 1) The litters amounts and total thickness in Pinus tabulaeformis were the largest,6.37 t/hm2 and 4.0 cm respectively,followed by Robinia pseudoacacia,and the least were in Platycladus orientalis.2) The largest water-holding capacity of litter was Robi... |
