摘  要：
在山东省莱芜市石质山地生态修复区,对5种人工林分枯落物层涵蓄水分特征进行了观测。结果表明: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在95.0%~208.2%之间,以阔叶林明显高于针叶林。②不同林分枯落物蓄积量在8.8~19.6t/hm2之间;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在1.8~2.6mm之间,针阔叶混交林依次高于针叶林、阔叶林。③不同林分枯落物层有效拦蓄水深在0.8~1.6mm之间,依次为针阔叶混交林大于阔叶林、针叶林(具体为刺槐×侧柏混交林>刺槐单纯林>麻栎单纯林>赤松单纯林>赤松×侧柏混交林)。④在石质山区生态修复的林业工程中,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,以提高人工林分枯落物层在防止土壤侵蚀和涵养水源中的作用。

摘  要：
Water-holding capacity of litter layer for different forest was researched on rocky mountain region,in LaiWu City,Shandong province.Results indicate that Litter layer of forest play an important role in water-holding capacity.The maximum water-holding percentage of litter layer for five kind of forest is 95.0%～208.2%,being larger for broad leaved forest 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.The maximum water-holding capacity of litter layer for five kind of forest is 1.8mm～2.6mm,being larger for coniferous-broad leaved mixed forests than that for coniferous forest and broad leaved forest.③The difference of effective interception in five kind of forest was 0.8mm～1.6mm,and where: coniferous-broad leaved mixed forests > broad leaved forest > coniferous forest,the order was mixed forest of Black Locust and Platycladus orientalis>pure forest of Black Locust > pure forest of Quercus acutissima > pure forest of Pinus densiflora > mixed forest of Pinus densiflora and Platycladus orientalis.
