| 摘 要： | 基于样地调查和群落学的分析,采用总优势度(SDR)、Shannon-Wiener指数、Simpson指数和群落均匀度Pielou指数研究了九连山主要森林群落灌木层的物种数量组成及其多样性.结果表明:(1)多样性指数:在所有样地中,多样性指数最大的是丝栗栲(Castanopsis fargesii)林(2.353),最小的是天然猴头杜鹃(Rhododendron simiarum)林(0.973);(2)均匀度指数:不同群落均匀度指数差异较小,最大的是次生毛竹(Phyllostachys pubeseerts)林(0.961),最小的是杉木(Cunninghamia lanceolata)林(0.564);(3)优势度指数:各群落优势度指数与多样性指数呈现出较大负相关趋势,优势度值最大的是杉木林(0.431),最小的是丝栗栲林(0.091).通过对比分析各群落不同层次物种的Shannon-Wiener多样性指数,各群落多样性指数的平均值以灌木层最大,乔木层最小,且同一群落中灌木层的种群密度明显高于乔木层,灌木层与乔木层之间的物种组成存在较大差异,预示着九连山森林群落间的种群动态变化及演替趋势. |

| Abstract: | Field investigation was carried out for species diversity of shrub layers of the main communities in Jiulian Mountain of Jiangxi Province in south China.The main indices included the Shannon-Wiener index(SW),the simpson dominance index(SN),the homogenization index(PW) and the sum of dominance ratio(SDR) were adopted in the paper to study the species diversity and the importance of shrub layers.The results indicated that the different indices can effectively express the composition and structure characterist... |
