【摘要】 文章采用生态学方法对阳台山植物群落进行调查,结果的分析显示随海拔升高,均匀度指数(J,Ea) 和丰富度指数(H′,D)降低,种间相遇指数(PIE)升高,群落表现一定的垂直分布规律,而植物群落的物种丰富度指数(S)表现非单调性变化。从调查结果出发,结合丰富园林植物多样性的实践要求,提出增加丰富度是基本,提高均匀度是关键,丰富多样性是根本。更多还原

【Abstract】 The paper investigated the plant communities in Yangtai Mount using ecological investigating methods.Upon the a- nalysis,the evenness index and the diversity index decrease,and the PIE index increase with the elevation of the altitudes, but the richness index S dose not change monotonically.Generally,the plant communities have some rules in the vertical dis- tribution naturally.Combining the practical needs of improving the diversifies of landscape plants,the paper points that in- creasing the richness is the base,improving the evenness is the key-point and enriching the diversity is the eventual goal.更多还原
