摘　　要：为分析杨树林节肢动物群落结构动态变化规律,在对安徽合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J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。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-April, May-August, September-October,and Novemer-December. Both of clustering and optimal cut-apart reflected the seasonal dynamic tendency.
