| 摘 要： | 为分析杨树林节肢动物群落结构动态变化规律,在对安徽舍肥杨树林系统调查的基础上.分别用通径分析、聚类分析和最优分割等方法进行了分析.结果表明,群落中均匀度.,与多样性H'关系密切,物种数S、优势集中性C和物种丰富度R是影响群落多样性的重要因素.全年13次调查结果可将群落聚为5类,D为1.474 1.反映出群落的变化状况,聚类交替现象则反映出群落在较长时间内的复杂性.将群落结构按1年中的时间顺序分割为4段(3～4月、5～8月、9～10月、11～12月),反映了群落结构的季节性变化规律.

| Abstract: | Based on the principles of community ecology,the dynamic changing patterns of structure of arthropod community in poplar stand were analyzed by path analysis,cluster analysis and optimal cut-apart.The results of path analysis showed that diversity indexes in arthropod community were decided by evenness,numbers of species,richness and dominant concentration.The clustering result showed that community could be grouped into 5 clusters.The optimal cut-apart of the community was divided into 4 stages,i.e.,March-... |
