| 摘 要： | 对六盘山不同植被的地被物分布特征进行研究发现，华北落叶松、白桦和油松林下草本植物物种丰富。辽东栎林枯落物叶片宽厚肥大，分解后枯落物较为松软，厚度最大，枯落物总储量仅次于华北落叶松。不同森林植被枯落物中，针叶枯落物所占比例最大。未分解层储量／厚度比值小于半分解层，9月份针叶林枯落物储量／厚度比值最大。天然次生林辽东栎林植被结构复杂，尽管不断有枯落物补充，枯落物却能迅速破碎分解，一方面能够迅速补充土壤养分含量，另一方面能够在地表形成更为疏松的枯落物层，因此7—9月份辽东栎林枯落物变化较大。 |

| Abstract: | The characteristics of forest floor in Liupan Mountain was studied.It was found that the herbage diversity in the forest of Larix principis-rupprechtii,Betula platyphylla,and Pinus tabulaeformis was abundant.Due to the fleshy leaves of Quercus Liaotungensis forest,litter layer was rather loose after litter was decomposed,so that litter depth was the greatest and litter biomass was lower than that in Larix principis-rupprechtii forest.Furthermore,the leaf litter was the main configuration.Ratio of litter bio... |
