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 results showed that the species composition of vascular plants in the evergreen coniferous and broad-leaved mixed forest in Niumulin Nature Reserve of Fujian Province is rich in species composition, geographical composition, vertical structure and species diversity, There are 119 families, 62 genera, 38 families, of which 38 species belong to absolute genus. The geographical features of the seed plants are 37 genus, 37 genera, 64.91% of the total genus, and 19 genera of the temperate zone, accounting for 33.33% There are four sub-layers in the layer, and the species and the number of the trees in the shrubs and vines are abundant, with fewer herbs. The diversity of each part in the community is shrub layer> arbor layer> herb layer> interlaminar plant.
