| 摘 要： | 本文研究了贵州紫云典型喀斯特峰丛洼地植物群落的物种丰富度，多样性，均匀度和生态优势度，探讨了这一次生植被植物群落的种－多度的分布特征，并进行了类型划分和主要种群分布格局、生态位宽度、生态位重迭度的测定，结果表明：越趋近原生性较强的群落具有更为稳定的多样性指数和生态优势度。该次生植被的植物种群由于个体差异较大，对生态小生境分化不大及对资源的充分利用尚存较大潜力可向更深层次的方向发展。

| Abstract: | The species richness,diversity,evenness and ecological dominance of plant community of karst peak and depression in ZiYun county of GuiZhou province were studied. The species-dominance distribution features and their types were studied and divided. The distribution patterns niche width and niche overlap of main populations were measured. The results showed that the community with more natual Charaeters had steady diversity index and ecological dominance. The population with great difference of individuals and few differential to ecological habitats developed to the successive stages or directoin with more resource utilization. |
