摘要
应用除趋势对应分析（ＤＣＡ）对长白山不同森林类型腐木生苔藓植物分布研究表明，长白山红松阔叶混交林、暗针叶林以及两者之间的过渡林林下腐木生苔藓植物组成明显不同．红松阔叶混交林以尖叶匍灯藓、毛尖羽藓、细枝青藓等为主；过渡林以尖叶匍灯藓、鞭枝疣灯藓、羽藓、腐木藓、塔藓等为主；暗针叶林的以塔藓、钩枝镰刀藓、拟垂枝藓、曲背藓、毛梳藓等为主．暗针叶林林下腐木生苔藓植物发生量最大，物种的多样性也最高．海拔高度和林冠郁闭度是影响长白山森林林下腐木生苔藓植物生态分布的主要因素．
pplication of DCA to study the
ecological distribution of saprophytic bryophytes in Changbai Mountains showed that there
existed differences in the components of saprophytic bryophyte communities in Pinus
koraiensis broad leaved mixed forest, dark conifer forest, and the transitive forest between
Pinus koraiensis broad leaved mixed forest and dark conifer forest. In Pinus koraiensis
broad leaved mixed forest, Plagiomnium cuspidatum, Thuidium philibertii and
Brachythecium buchananii were the main saprophyte bryophytes. Plagiomnium cuspidatum,
Trachycystis flagellaris, Thuidium cymbifolium, Callichladium haldanianum and Hylocomium
splendens were the main saprophytic bryopytes in the transitive forest between Pinus
koraiensis broad leaved forest and dark conifer forest. Whereas, Hylocomium splendens,
Sanionia uncinata, Rhytidiadelphus triquetrus, Oncophorus wahlenbergii and Ptilium crist
castrens were the main ones in dark conifer forest. The total coverage and species diversity of
saprophytic bryophytes were the highest in dark conifer forest. Altitude and forest canopy
density were the two important environmental factors influencing the distribution patterns of
saprophytic bryophytes in the forest ecosystems in Changbai Mountains.
