摘要
对福建省牛姆林自然保护区常绿针阔叶混交林的区系组成、地理成分、垂直结构、物种多样性等特征研究结果表明,该混交林群落维管植物种类组成丰富,600m^2样地内有38科62属119种,其中以常绿高位芽植物占绝对优势;种子植物地理成分中热带性质属37属占64.91％,温带成分19属占33.33％;群落分层现象明显,乔木层可分4个亚层,乔、灌木及藤本植物种类和数量均丰富,草本植物较少;比较群落各部分多样性水平为灌木层>乔木层>草本层>层间植物。
The community selected from needle and broad-leaved mixed evergreen forest in Niumulin Nature Reserve Zone is analyzed on the basis of study on the floristic geographical composition, sectional structure and species diversity of the community. The results show that the flora of vascular plants contains 119 species and a number of 62 genera in 38 families in the plot with 600m . Among the floristic geographical elements of seed plants, all sorts of tropical genera and temperate ones amount to 37 and 19, making up 64.91 % and 33. 33 % of all the 62 genera respectively. The community is with more and clearer layers and sublayers in the complicated vertical stratification, and the tree layer can be divided into 4 sublayers, and there are a large number of tree, shrub and liana in it, and the herb is lack of. The species diversity index order for different sections of the community is as follows: shrub layer>tree layer>herb layer>interstratum plant.
