摘要
该文通过群落样地调查,采用多样性指数对该群落物种多样性进行测定,结果表明,该群落1200m2样地有维管植物69科102属133种,400m2的样地内平均有78.3±6.0个物种,Shannon-Wiener指数(H)、Simpson指数(D)和Pielou均匀度指数(Jsw)分别为4.228、0.972、0.865。主要层次物种丰富度(S)表现为:灌木层>乔木层>草本层;H、D表现为:灌木层>草本层>乔木层,Jsw表现为:草本层>灌木层>乔木层。
By sample-plot survey and utilization of diversity index, the author determinates species diversity of Machilus versicolora community in Mangdang Mountain of Fujian. The results are as follows： there are 69 families, 102 genuss and 133 species of vascular plants in 1200m^2 sample plot of Machilus versiecolora; there are 78.3±6.0 species in 400m^2 sample plot on average; the index number of Shannon-Wiener （H）,Simpson （D）and Pielou degree of homogeneity （Jsw）are 4.228,0.972,0.865 respectively. Species richness level of major layers： shrub stratum〉arbores- cent stratum〉field stratum;Indexes number of H and D：shrub stratum〉field stratum〉arborescent stratum; Jsw index number：field stratum〉shrub stratum〉arborescent stratum.
