摘要： 为了深入了解油茶园节肢动物群落多样性的影响因子，本文对油茶园节肢动物总群落、植食类和捕食类亚群落的多样性与其主要生态学指标关系进行了通径分析。结果表明：群落多样性H’与均匀度J、物种丰富度R及物种数S呈正相关，而同优势集中性C和优势度d呈负相关。因此，提高油茶园节肢动物群落的多样性可通过营造油茶园生境以增加节肢动物群落均匀度J、物种丰富度R和物种数S而减少物种优势集中性C和优势度d来实现。

Abstract: To thorough investigate the effect factors of arthropod community diversity, the relations between diversity index and its main ecological indices of total communities and sub-communities were analyzed by path analysis. The results showed diversity index had a positive correlation with evenness and species richness, while a negative correlation with dominant concentration and dominance. Therefore, promoting the evenness, species richness and species of arthropod community could increase the diversity of arthropod community whereas decreasing dominant concentration and dominance through ameliorating condition in oil camellia orchard.
