摘要：对江西大岗山林区常绿阔叶林、毛竹林和杉木林枯落物的水文性能进行研究,结果表明:(1)常绿阔叶林、毛竹林和杉木人工林枯落物现存量分别为474.18,516.92和598.30 t/km2。(2)三者枯落物的持水量分别为吸水后10 h,20 h和20 h达到饱和稳定状态。(3)常绿阔叶林、毛竹林和杉木人工林枯落物的吸水速率均在0-6 h急剧减小。毛竹林枯落物的吸水速率随时间变化最为剧烈,而常绿阔叶林则较为平缓。(4)毛竹林枯落物对降水的有效拦蓄能力最强,水文生态效应显著。
Research on litter hydrologic characteristics of evergreen broad-leaved forest, Phyllostachys pubescents stands and Cunninghamia lanceolata was carried out in Mountain Dagangshan in Jiangxi province. The results showed that：（1 ）the amount of the present remaining litters of evergreen broad leaved forest,Phyllostachys pubescents stands and Cunninghamia lanceolata was 474. 18, 516.92 and 598.30 t/km^2 respectively. （2）After 10 h, 20 h and 20 h, the water holding capacity of the litter layer of the three reach its saturated stable status. （3）The litter water holding rate of the three forest types decreased seriously in 0-6 h. That of Phyllostachys pubescents stands changed greatly, while that of evergreen broad-leaved forest varied slowly. （4）Water effective conservation ability and hydro-ecological efficiency of litter under Phyllostachys pubescents stands was better than that of the other two.
