摘要
运用棋盘格子调查法对吉首紫菀(Aster jishouensis)生物群落的物种多样性指数、物种丰富度和均匀度指数进行了分析。结果表明,吉首紫菀群落的组成成分简单,植物物种比较贫乏;其物种多样性指数、物种丰富度和均匀度指数基本上表现出一致的变化趋势。
Using chessboard grid survey method,the species diversity index,species richness index and species evenness index of the biological community of Aster jishouensis were analyzed.The results indicated that the composition of the A.jishouensis community was simple and plant species was relatively rare.The species diversity index,species richness index and species evenness index of A.jishouensis showed the similar varying trend.
