| 摘要: |
| 应用Margalef物种丰富度模型指数Ds、Shamnon-weaver信息多样性指数H＇和Pielou均匀度指数Jsw，分析了太白山不同林带(亚带)蚁科昆虫的丰富度、多样性及均匀度，并根据相似系数C，对9个不同林带(亚带)进行了系统聚类分析。结果表明，随着太白山海拔高度及森林植被组成的变化，不同林带分布的蚁种组成有较大的差异，在海拔低、植被组成丰富的林带(亚带)，分布的蚁种多、数量大，丰富度和多样性指数高；在海拔高、植被组成相对简单的林带(亚带)，分布的蚁种少、数量小，多样性差；南坡各林带(亚带)蚁种的丰富度和多样性指数均大于相同海拔高度的北坡林带(亚带)；9个不同林带(亚带)可被分为3类，并最终在相似系数0.180的水平全部聚合在一起。 |

| Abstract: |
| The species diversity of ants in different forest belts of Mt.taibai.was studied.Species abundance,species diversity and species evenness were analyzed by using Margalef species abundance model and Shannon-Wiener biodiversity indes H＇and evenness indexes Jsw respectively.Based on similarity coefficients,nine forest belts were clustered with the systematic clustering.The result showed that with the variation of altitude and forest belt,there was great difference of ants’distribution in different forest belts.In low altitude and abundant forest belt,ant species,population and biodiversity indes and abundance index were high;on the contrary,they were low.Ant species abundance and biodiversity index in south slope was higher than that of the same altitude in north slope. |
