摘　　要：福建山樱花群落高矮和立木密集程度不同样地间存在很大的差异,但垂直结构均较简单。以中小乔木和灌木占数量优势,以常绿植物占绝对优势,壳斗科、樟科、山茶科为优势科,拟赤杨、青冈、细叶青冈、山胡椒、香桂为优势树种;层间植物较少,且均为木质藤本植物;生活型组成则以高位芽植物占显著优势(72.1%)。群落的外貌是由小型叶(69.6%)、单叶(90.7%)、草质叶(43.8%)或革质叶(39.8%)为主的常绿高位芽植物所决定的,具有明显的亚热带常绿阔叶林特点。群落乔木树种以中小径级占绝对优势,中径级和大径级的很少,群落处于旺盛生长期;但对群落立木结构研究表明,福建山樱花种群已处于衰退模式,有即将在群落中消失的可能,需加强对其保护研究。The height and density of Cerastts campanulata community are the significant variation between various spots. Fagaceae, Theaeeae and Laumceae are the predominant families, and Alniphyllum fortunei, Cyclobalanopsis glauca, Cyclobalanopsis myrsinaefolia, Lindera glauca and Cinnamomum subavenium are the predominant species in these families. Evergreen plants hold a biggest position including evergreen microphanerophytes and nanophanerophytes, simple, miniature, the grass-or the leather-texture leaves, which demonstrate characteristies of the evergreen broadleaf forest in the subtropical region of China. The DBH class distribution of the arbor tree species shows all obvious pyramid type. Seedlings and young saplings account for the majority of the community showing that the community is in the vigorous growing stage. Analysis on structure of community indicated that C. campanulata displayed a decline tendency. Therefore, C. campanulata isan endangered species, which must be preserved through in situ and ex situ conservation.
