| 摘 要： | 对浙江省桐庐县7种不同林分类型枯落物进行水文效应研究表明:(1)不同林分类型枯落物持水量、吸水速率随时间的动态变化规律基本相似。持水量随浸泡时间的增加呈上升趋势,但当浸泡8 h之后,趋势变缓;不同林分类型的吸水速率在6 h内变化最快,随着时间继续增加,吸水基本达到饱和。(2)不同林分类型枯落物都具有不同程度的蓄水、保水作用,最大持水率在101.78%~319.91%之间,最大持水量大小顺序为:落叶阔叶林>未成林>毛竹林>经济林>杉木林>常绿阔叶林>马尾松林,阔叶林明显大于针叶林。

| Abstract: | Hydrological effect for different forest vegetation was researched in Tonglu,Zhejiang province.Results indicate that:(1)The dynamic course of water-holding capacity and water absorption rate are similar in different forest vegetation types.With the immersion time extending,the water-holding capacity is increasing.When the litter layer is immerged in the water for 8 hours,the water-holding capacity will reach the bigger value.From then on,with the time extending,the increasing range shows small.The water abs... |
