漳平市天然次生阔叶林群落特征

应用群落生态学方法 ,对漳平市天然次生林群落特征采用相邻格子法进行调查 ,研究了群落生物多样性、种群结构、空间格局 .结果表明 :群落物种丰富 ,乔木层、灌木层相对于其它各层的多样性指数、丰富度和优势度指数均较大、均匀度较小 .群落中主要建群种 :米槠、毛栲的种群分布格局为均匀分布 ,木荷、石栎的种群分布格局为聚集分布 ,栲树、绒楠的种群分布格局为随机分布 .该群落处在发展阶段 ,尚未稳定 ,应继续封护 ,促进群落的自然演替

The Character Study of Sub-natural Forest Community

In this paper,used the methods of community ecology and contiguous grid,the biodiversity?community structure and space pattern were analysed.The results show that the species are abound and the index of diversity?abundance and superiority of tree layer and shrub is larger than others.The distribution pattern of constructive species including Castanopsis carleesii and Swida walter is uniform;Schima superba and Lithocarpus glaber is clumped and Castanea fargesii,Machilus velutina is random.The community is not steady and should be protected for the community resuming.
