摘　　要：红豆树是国家Ⅱ级保护珍稀濒危植物,开展百年红豆树群落学特征研究,对于保护红豆树古树群具有重要的意义。在霞浦县崇儒乡,用群落学方法对百年天然红豆树群落特征进行了定量研究。结果表明:红豆树、刨花润楠和毛锥3个树种在乔木层中占据绝对优势,三者的重要值分别为84.1%、49.3%和29.5%。根据群落中各树种的重要值,可将其命名为"红豆树+刨花润楠+红楠"群落。红豆树古群落垂直结构丰富,乔木层、灌木层和草本层分层明显,上层木为红豆树和刨花润楠,中层木为红楠、毛锥、钩锥等,林下更新层主要为红豆树、刨花润楠、毛锥。红豆树群落红豆树种群呈增长型,天然更新良好,在无干扰状态下红豆树群落能够实现自然更新。Ormosia hosiei is theⅡ-grade state protection of rare and endangered plant,characteristics of community of century O.hosiei was conducted,which offers important significance for protection of O.hosiei populations.In Chongru Township of Xiapu County,quantitative study on community characteristics of natural forest of century O. hosiei were conducted by using community method.Result shows that three tree species （O.hosiei,Machilus pau-hoi ＆amp; Castanopsis fordii ）occupied the absolute advantage in the tree layer,and the important value of the three is 84.1%,49.3% ＆ 29.5 respectively;according to important value of each tree species in the community,it can be named as “O.hosiei ＋ Machilus pauhoi ＋ Machilus thunbergii ”community.Vertical structure of palaeocommu-nity for O.hosiei is rich;tree layer,shrub layer and herb layer layered obvious.Upper wood is O.hosiei and Machilus pauhoi ;middle wood is Machilus thunbergii ,Castanopsis fordii ＆ Castanopsis tibetana .Regeneration layer under the forest are mainly O.hosiei,Machilus pauhoi ＆ Castanopsis fordii .O.hosiei population in O.hosiei community appears growth-oriented,natural regeneration being optimal;O.hosiei community can realize natural re-generation under the conditions of no disturbance.
