| 摘 要： | 文章以赛罕乌拉4种典型林分为对象,对其林下植被及枯落物层的水源涵养功能进行了初步研究。结果表明:①林分结构越复杂,林下植被物种多样性越大,其截留降雨的能力也越大。②4种林分枯落物的蓄积量范围在12.44～31.60t/hm2,针叶林枯落物的蓄积量明显高于阔叶林。③枯落物持水率大小顺序为山杨林>白桦林>山杨白桦林>落叶松林,山杨林分枯落物的最大吸水率(511%)为落叶松林分(280%)的1.8倍。④枯落物最大持水量的大小为阔叶混交林>针叶林>阔叶林。枯落物最大拦蓄量大小表现为:针叶林>阔叶混交林>阔叶林。落叶松林的有效拦蓄量最高(为6.56mm),白桦林分有效拦蓄量最小(为3.38mm)。

| Abstract: | Taking four typical stands for object in nature of reserve Saihanwula,this paper research water conservation functions of undergrowth vegetation and litter.The result showed that （1）The more complex of stand, the greater of species diversity in understory vegetation, the greater ability of its interception of rainfall. （2）The volume of the four stands types of litter in the range of 12.44-31.60t/hm2,accumulation of coniferous forest litter was significantly higher than the broad-leaf forest.（3）The water-holding of litter size order was poplar forest〉birch forest〉 poplar birch forest〉 larch forest,The water absorption of litter of poplar forest （511%） was 1.8 times the larch stands （280%）. （4）The maximum moisture capacity of litter was coniferous and broad-leaf mixed forest 〉 coniferous forest〉 broad-leaf forest. The maximum interception of litter was coniferous forest〉 coniferous and broad-leaf mixed forest 〉 Broad-leaf forest. Effective retaining content of larch forest was the highest （6.56mm）, effective retaining content of Birch forest was the least（3.38mm）. |
