长白山地区共有苔藓植物65科179属437种,32个变种和亚种。其中,石生和岩面薄土生种类(saxicolous bryophyte)最丰富,其次为腐木生种类(saprophytic bryophyte)和树生种类(epiphytic bryophyte),再次为土生种类(soil and humus bryophyte)。沼泽地、水体等生境中的种类(peat, marsh and water bryophyte) 相对较少。地面生苔藓植物的物种丰富度以暗针叶林(dark conifer forest)最高,而多样性以落叶松-沼泽地(Larix olgensis-bogs)和暗针叶林为最高;腐木生苔藓植物的物种丰富度和多样性均以暗针叶林为最高,树附生苔藓植物的物种丰富度和多样性以暗针叶林以及红松阔叶混交林(Pinus koraiensis broad-leaved mixed forest) 与暗针叶林间的过渡林为最高。定性分析表明,海拔高度、林冠层郁闭度和林内湿度、土壤酸度、含水量、林下倒木的丰富程度等可能是影响本地区苔藓植物多样性的重要环境因子。

There are 469 species of bryophytes (including 32 taxa under species) belonging to 179 genera and 65 families in Mt . Changhai. The species richness ranged from the highest to the lowest as saxicolous bryophytes , saprophytic bryophytes , epiphytic bryophytes , soil and humus bryophytes and peat , marsh and water bryophytes. For soil and humus bryophytes , the species richness is highest in dark conifer forest ,Shannon index is highest in L arix olgensis- bogs and dark conifer forest . The species richness and Shannon index for saprophytic bryophytes are highest in the dark conifer forest , and those for epiphtic bryophytes are highest in both the dark conifer forest and the transitive forest between Pinus koraiensis borad-leaved mixed forest and dark conifer forest . Qualitative analyses showed that altitude , canopy density , soil acidity , soil water content and richness of rotten wood in the forest could be the important environmental factors influencing the diversity of bryophytes. Among them , the humidity and canopy density rank the first .
