摘要: 苔藓是具有较多种类的一类绿色植物群,是生物多样性的重要组成成分。缘于苔藓的可变水性、体表直接吸收水分和营养以及独特的繁殖与传播方式,苔藓几乎存在于所有的生态系统之中。除极地冻原、温带苔藓沼泽等以苔藓为优势的植被类型外,苔藓还通常在维管束植物群落中形成自己的群落。苔藓是重要的初级生产者之一,在物质循环中起着重要的作用,影响森林植被的水分平衡,也是某些演替过程中的重要先锋植物。苔藓与其它生物类群的生活和生存有密切联系,尤其是苔藓群落所营造的生境,促进和保护了生物多样性。苔藓与人类生活的关系日益密切。由于苔藓与生境的强烈相关性,其多样性所受到的威胁主要源于生境的破坏,加之人们对苔藓的了解远远少于其它高等植物,这种威胁更应引起关注。

AbstractWith nearly 23000 species,various ecological adaptation,unique life history and poikilohydrous water relations,bryophytes are important components of the biodiversity of the world,In virtue of their ecophysiological attributes,bryophytes grow in all vegetation types,and always form their own societies within vascular plant societies.They are important for other organisms,By creating a special 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,which has been neglected by the public,Otherwise,these highly specialized and sensitive organisms would disappear.The damaged habitat is also a main threat to bryophytes.
