| 摘 要： | 对法国阿尔卑斯山(Mt.Alps,France)6个溪流型喀斯特瀑布水生苔藓植物群落进行了研究。报道典型瀑布水生苔藓群落14个,苔藓植物种类由11科16属20种(含变种亚种)组成;生殖系统由雌雄异株(Dioecious,95%)和雌雄同株异苞(Autoecious,5%)两种类型构成,无性繁殖是繁殖的主要方式;区系地理成分含北温带分布(60%)、欧洲-北美分布(10%)、旧世界温带分布(5%)和世界广泛分布(25%)等4种成分;生活型含高丛集型(20%)、矮丛集型(10%)、交织型(60%)和平铺型(10%)4种类型。根据喀斯特沉积环境特征,划分瀑布水生苔藓群落为峡谷瀑布苔藓群落、温泉瀑布苔藓群落、瀑布水帘洞苔藓群落、悬崖瀑布苔藓群落和悬崖季节性瀑布苔藓群落等5种生态类型。法国阿尔卑斯山溪流型瀑布生物喀斯特沉积物具有分布广泛,但沉积规模较小的特点。 |

| Abstract: | An ecological survey was conducted at six stream karst waterfalls in Alps,France in 2000,about 14 aquatic bryophyte communities were recorded.The bryoflora of karst waterfalls consists of 11 families,16 genera,and 20 species including subspecies and variety.The reproductive systems consist of two types: the Dioecism is 95% while the Autoecism 5%.The phytogeographcial elements of the bryoflora include North Temperate(60%),Old temperate(5%),Europe-North American elements(10%) and Cosmopolitans(25%).The life-forms are Tall turfs(20%), Short turfs(10%),Mats(10%) and Wefts(60%).Five ecological types of aquatic bryophyte communities can be distinguished in stream karst waterfalls: canyon waterfall community,warm spring waterfall community,waterfall travertine cave community,cliff waterfall community and cliff seasonal waterfall community. |
