潜山县茶园节肢动物群落多样性与相应组分的通径分析

Path Analysis of the Diversity Index and Other Components of Arthropod Communities in Tea Garden of Qianshan Area

[目的]研究潜山县茶园节肢动物群落的多样性与其他结构特征指数的关系。[方法]采用通径分析方法,对潜山县茶园节肢动物群落的多样性与其他特征指数的关系进行分析。[结果]群落均匀度指数对多样性的直接作用为0.813 0,优势集中性指数对多样性的直接作用为-0.361 4,它们对多样性的作用较为明显。[结论]该研究有助于阐明茶园节肢动物群落多样性与其他组分的关系。

[Objective] The research aimed to study the relationship between the diversity index and other ecological indies of arthropod community in tea garden of Qianshan area.[Method] The relationship between the diversity index and other ecological indies of arthropod community in tea garden of Qianshan area were analyzed by path analysis.[Result]Pielou index of arthropod community had a direct effect on diversity index of 0.813 0.The dominant concentration had a negative correlation with the diversity index of-0.361 4.These two indexes had obvious effects on diversity index.[Conclusion] The research was favorable for illuminating the relationship between the diversity and other components of arthropod community.
