摘  要:
利用葛藤节肢动物类群有关的结构指数进行了主分量分析 (PCA) ,构建了评价类群结构的综合指标 (第 1主分量和第 2主分量 ) ,并根据第 1和第 2主分量得分进行二维排序 ,结果表明葛藤节肢动物类群结构在时间系列上保持稳定 ,但在个别时间点上表现出差异和波动 ;结果还表明 ,多样性指数H′是衡量节肢动物类群结构最重要的指标。

摘  要:
The principal component analysis (PCA) on structure of group of arthropods on Kudzu (Pueraria lobata Ohwi) was conducted. The first and second principal component equations were put forward and used to arrange rank. It showed that the structure of group of arthropods was stable and that the index of diversity, H′, was the most important parameter.
