【摘要】 探讨了缙云山森林节肢动物群落的物种组成,以及森林演替对节肢动物群落组成结构的影响。研究结果表明:缙云山节肢动物群落中的优势组成类群是鳞翅目和蜘蛛类群,鳞翅目物种丰富度和多度几乎占整个群落的40%～50%,蜘蛛类群占10%～15%。森林演替对节肢动物群落的数量特征影响不明显,这与森林植物群落物种丰富度及毗邻环境的特征有关。但森林演替对节肢动物群落的物种更替影响极大,一方面表现为不同森林演替节肢动物群落的物种组成差异较大,另一方面影响节肢动物类群物种的更替速率。各组成类群都表现出在演替初期物种的更替速度比演替后期的快。这与森林演替过程中,森林环境渐趋稳定相一致。更多还原

【Abstract】 An experiment was conducted to study the species composition of arthropod communities and the effect of forest succession on arthropod diversity in Jinyun Mountain,Chongqing. Results show that the dominant compositional groups in arthropod communities are Lepidoptera and spider group,accounting for 40 percent to 50 percent and 10 percent to 15 percent of species richness,respectively. The effect of forest succession on species richness in arthropod communities is not obvious,but the effect on species composition is notable. The similarity between the communities is low,and the subrogation rates of species between the communities are different. The subrogation rate in the late succession stage is slower than that in the early succession stage,which is consistent with forest environment that gradually tends to be stable in the late succession stage.更多还原
