摘    要:在对元江自然保护区分布的水青树群落进行野外调查的基础上,分析其物种组成与结构、更新特点与保护对策.结果表明:元江自然保护区水青树群落共记录维管植物32科46属55种及变种,水青树是群落的优势树种,山茶科、樟科和蔷薇科是群落伴生植物的主要组成科.水青树具有在林窗或林缘下更新的特点,在光照条件好,郁闭度不大的次生林下,其更新幼苗生长能力较强.当地的水青树群落结构较典型,自然更新良好,属我国水青树分布区原生状态较好的群落类型.在元江自然保护区的管理中应将水青树群落类型作为重点保护对象,并且与其生境保护同时进行,实施就地保护.

关 键 词:水青树  群落学特征  元江自然保护区

Abstract:The species composition, morphological structure, regenerations characteristics and protection countermeasures of Tetracentron sinense communities distributed in Yuanjiang Nature Reserve were studied on the basis of field survey. It was showed: There were 55 species or varieties of vascular plants belonging to 46 genera, 32 families in T. sinense communities in the nature reserve. Inside the communities, T. sinertse was the predominant species, Theaceae, Lauracea and Rosaceae were the main families whose species were the major companions of T. sinense species. T. sinense could regenerate well under the gap and canopy edge, its seedlings could also regenerate and grow well under the canopy of sparse secondary communities where there was enough sunshine. The T. sinense communities in Yuanjiang Nature Reserve had typical structure, belonging to comparatively original 7: sinene community type in domestic distribution areas. It was proposed that T. sinense communities, as well as their habitats inside the nature reserve should be well protected as in situ conservation.
Keywords:Tetracentron sinense  community characteristics  Yuanjiang Nature Reserve
