| 摘 要： | 通过对保康县8个野生蜡梅群落样地进行调查研究。结果表明:群落以蜡梅为主要建群种,蜡梅在多度(88)、重要值(29.82)和频度(100%)方面均为蜡梅群落灌木层中最高者,蜡梅在群落中处于绝对优势的地位。刺滩沟蜡梅群落的丰富度指数(28)、Simpson指数(0.84)和Shannon-Wiener指数(1.06)为8个群落最大者。蜡梅群落灌木类植物物种的Pielou均匀度指数与多样性指数总体表现出较为相似的特征,即物种多样性高,均匀度也较高。物种丰富度、多样性、均匀度均表现出相似的变化趋势。

| Abstract: | Through the study on 8 wild Chimonanthus praecox populations in Baokang County,this paper found out that the abundance(88),importance value(28.92) and frequency(100%) of Chimonanthus praecox were the highest among all species of basekage.Chimonanthus praecox held the superiority position in all populations.The species richness(28),Simpson's index(0.84) and Shannon-Winner's diversity index(1.06) of the Citangou wild Chimonanthus praecox population are higher than those of the other populations.The evenness i... |
