| 摘 要： | 以苔藓植物盖度为指标，应用双向指示种分析(TWINSPAN)和除趋势对应分析(DCA)对长白山地区不同森林类型36个样地的树附生苔藓植物群落分布格局进行了研究。结果表明，长白山地区树附生苔藓植物的分布格局与森林植被类型相对应，可分成落叶松林、岳桦林、暗针叶林、暗针叶林与红松阔叶林间过渡林、红松阔叶林、白桦林6类树附生苔藓植物群落类型，文章分析了影响树附生苔藓植物群落生态分布的环境因素。

| Abstract: | DCA and TWINSPAN were applied in this study of the community distribu tion patterns of epiphytic bryophytes based on the cover of epiphytic bryophytes in different forests in Changbai Mountain. The results showed that the distribu tion of epiphytic bryophytes is well correlated with forest types. Epiphytic bry ophyte communities in this area can be divided into six groups,which are distrib uted in Larix olgensis forest, Betula ermanii forest, dark conifer forest, transition forests be tween Pinus koraiensis broad-leaved mixed forest and conifer forest, Betu la platyphylla forest and Pinus koraiensis broad-leaved mixed forest resp ectively . The factors influencing the ecological distribution of epiphytic bryophytes in Changbai Mountain were also analyzed and described. |
