摘  要：
为人工仿生态栽培八角莲,采用样方调查法对福建省三明地区八角莲群落的植物组成、群落结构和物种多样性进行了分析。结果表明:在20个样方共计2000m2的调查面积内,群落有维管植物99科197属285种,其中蕨类15科22属30种,裸子植物2科2属2种,被子植物82科173属253种。群落植物区系地理成分中亚热带性质明显,种子植物属的区系成分可为12个分布型和8个变型。其中,热带性分布属占59.62%,温带性成分占38.46%。生活型谱分析表明,高位芽植物占总种数的54.36%,以小高位芽占优势;高位芽以外的植物以地下芽占较大比例,达17.72%。群落垂直结构分为乔木层、灌木层、草本层,草本层以蕨类植物和多年生草本植物为主。群落垂直结构的Simpson指数和Shannon-Wiener指数值大小依次为草本层>灌木层>层外层>乔木层,其中,草本层和灌木层的各项多样性指数均显著大于乔木层和层外层。

摘  要：
The plant composition,community structure and species diversity of D.versipellis community in Sanming area,Fujian were analyzed by the plot survey method to provide a reference for artificial cultivation of D.versipellis.There are 285 vascular species,197 genera,99families;30ferns species,22 genera,15families;2gymnosperm species,2genera,2families and 253 angiosperm species,173 genera,82families in 20 sample plots with 2000m2.The geographical composition of the community flora belongs to the obvious mid-subtropical zone.The floristic element of spermatophyte genus can be divided into 12 distribution types and 8variant types.The tropical distribution types account for 59.62%of total generic number and the temperate elements account for 38.46% of total generic number.The biological spectrum analysis showed that the phanerophyte accounts for 54.36% of total species number and Microphanerophyta takes the dominant position in the community.Geophyta and chamaephytes account for a larger proportion and the herbaceous layer consists of ferns and perennial herb mainly.The vertical structure of the community consists of arborous layer,shrub layer and herbaceous layer.The Simpson index and Shannon-Wiener index of the community vertical structure is herbaceous layer>shrub layer>vine layer>arborous layer,and various diversity indexes of herbaceous layer and shrub layer are higher than arborous layer and vine layer.
