摘  要:
在山东省济宁市石质山区刘庄小流域,对5种人工林分枯落物层涵蓄水分特征进行了观测。结果为:不同林分枯落物层的蓄水保水功能具有明显差别。①5种林分枯落物最大持水率差别大约在85~198%之间,阔叶林明显高于针叶林。②针叶林枯落物蓄积量较大,因而持水量较高。5种林分枯落物最大持水量差别在1.5mm~2.5mm之间,以针阔叶混交林最高,其次为针叶林、阔叶林。③5种林分枯落物层有效拦蓄水深差别在0.6mm~1.4mm之间,依次为针阔叶混交林大于阔叶林、针叶林(具体为麻栎×侧柏混交林>刺槐林>麻栎林>侧柏林>赤松×侧柏混交林。结论为:在石质山区应尽量增加针阔叶混交林分或阔叶林分的培育,减少针叶林分,以提高林分枯落物层在涵养水源中的作用。

摘  要:
Water-holding capacity of litter layer in different forest stands was restudiedhed on rocky mountain region of Liuzhuang small watershed, in Jining City, Shandong province. Results indicate that Litter layer of forest plays an important role in water-holding capacity.①The range of maximum water-holding percentage of litter layer for five kind of forest is 85.0%~198.2%,broad leaved forest stand is higher than that for coniferous forest. ②Coniferous forest is still remaining higher water-holding capacity, owing to the existing amount of coniferous litter is larger than that of broad leaved stand. The maximum water-holding capacity of litter layer for five kind of forest is 1.5mm~2.5mm,coniferous-stand is higher than that for broad leaved mixed forests and higher than that for coniferous forest and broad leaved forest.③The difference of effective interception in five kind of forest was 0.61mm~1.43mm, and where:coniferous-broad leaved mixed forests > broad lea)ed forest > coniferous forest, the order was mixed forest of Quercus acutissima and Platycladus orientalis>pure forest of Black Locust > pure forest of Quercus acutissima> pure forest of Platycladus orientalis > mixed forest of Pinus densifiora and Platycladus orientalis.
