The role of bryophytes in biodiversity
苔藓植物的多样性研究

With nearly 23 000 species, various ecological adaptation, unique life history and poikilohydrouswater relations, bryophytes are important components of the biodiversity of the wold. In virtue of their ecophysiological attributes, bryophytes grow in all vegetation types, and always form their own xocieties withinvascular plant societies. They are important for other organisms. By creating a speial environment, they increase the species diversity in many ecosystems. Bryophytes play an important role in energy flow, nutrient cycling and water balance. It is necessary to define and emphasize the role of bryophytes in biodiversity, whichhas been negected by the public. Otherwise, these highly specialized and sensitive organisms would disappear.The damaged habitat is also a main threat to bryophytes.
