长江三峡库区及其邻近地区的残存稀有濒危植物群落

The archaic and relict communities of rare and endangered plants in the Three Gorge Reservoir Area and its adjacent area

长江三峡库区及其邻近地区的残存稀有濒危植物群落属于中亚热带常绿落叶阔叶混交林。群落所处自然环境和生境独特 ;群落中有数种至十余种稀有濒危植物群聚生长 ,且以其中的部分稀有濒危植物为优势种。独特的生境和良好的群落结构被认为是该类群落得以保存的主要原因 。

The archaic and relict communities of the rare and endangered plants in the Three Gorge Reservoir Area and its adjacent area belong to the mixed evergreen\|deciduous broad\|leaved forest in the central subtropical zone. The natural environments and the habitats of the communities are unique. There are several species or more than ten species of rare and endangered plants assembly grow in each community and some of these species are dominant species. The unique habitats and good communities structure are considered to be the main reason that these communities could be conserved. Enhancement of research of \%in situ \%conservation of these communities is suggested.
