摘要: 以大别山白马尖山区次生林样地死亡个体为研究对象,从群落发育、个体大小、物种多度和萌枝等方面分析了树种的死亡原因。结果表明,在大别山白马尖山区次生林中死亡个体的数目相对较多,死亡木以小径级为主,胸径5 cm以下的死亡木占死亡树木总数的30%以上;死亡树种的多度与其活立木多度呈正相关(P<0.05);3个样地中萌枝死亡的个体分别占41.7%、66.0%和60.0%。本研究表明竞争是大别山白马尖山区次生林树木死亡的主要原因,后续的研究应在更大多尺度上进一步探讨树木的死亡机制。

Abstract: The dead trees in Baimajian of Dabieshan mountain were analyzed to explore the reasons leading to tree death. The results showed more of the dead trees especially smaller class individuals dominated in this forest, dead trees with a breast diameter of less than 5 cm account for more than 30% of the total number of dead trees. The abundance of dead trees positively related to the abundance of living species. 41.7%, 66.0% and 60.0% of the dead trees were from the sprouting. Competition is the main reason of tree death in this secondary forest, further researches should explore the mechanism of tree death at larger scales.

Key words: Dabieshan mountain, Baimajian mountain, dead trees, competition, sprouting
