Bryophyte species diversity in main forest vegetations in Dongling Mountain of Beijing
北京东灵山主要森林植被中苔藓植物的物种多样性

An investigation was made on the vegetations and bryophytes in 32 sampling plots to study the species diversity of bryophytes in main forest vegetations in Dongling Mountain of Beijing.There were 79 species of bryophytes belonging to 33 genera and 16 families.Brachytheciaceae and Entodontaceae were the dominant families,and Entodon compressus and Anomodon minor were the dominant species.The species richness of the floor bryophytes was the highest under deciduous broadleaved mixed forest,and the lowest under birch forest.The community similarity of the floor bryophytes was the highest between Quercus liaotungensis forest and deciduous broadleaved mixed forest,and the lowest between Populus davidiana forest and Pinus tabulaeformis forest.The species richness of the epiphytic bryophytes was the highest under deciduous broadleaved mixed forest,and the lowest under P.tabulaeformis forest.The community similarity of epiphytic bryophytes was the highest between P.tabulaeformis forest and P.davidiana forest,and the lowest between Larix principis forest and birch forest.The biodiversity of bryophytes was correlated with forest vegetation,tree component,and microenvironment in the forests.
