【摘要】：【目的】研究典型植被下冬季大型土壤动物的群落特征。【方法】2015年12月采用手拣法收集并鉴定峨眉山典型植被下大型土壤动物。【结果】共检出大型土壤动物667只,隶属4门11纲26目。植被种类丰富、温湿度水平均较高的常绿、落叶阔叶混交林带中土壤动物数量和类群均较多。而植被类型较单一、温湿度水平均低、土壤冻结的寒温性针叶林带中土壤动物数量和类群最少。多样性结果分析表明,常绿阔叶林中大型土壤动物的Pielou指数(J)和Shannon-Wiener指数(H′)均为最高,而寒温性针叶林地下5cm中大型土壤动物的这两项指数最低;针阔混交林带和寒温性针叶林中大型土壤动物的Simpson指数(C)最高。【结论】植被类型和环境变化对大型土壤动物群落有强烈的作用,从而进一步影响了土壤生态过程。
[Abstract]:[Objective] To study the community characteristics of large soil animals in winter under typical vegetation. [Method] The large-scale soil animal under the typical vegetation of Emeishan was collected and identified by the hand-sorting method in December 2015. [Results] 667 species of large-scale soil animals were detected. The number and group of soil animals in the evergreen and deciduous broad-leaved mixed forest zones with a rich variety of vegetation and high temperature and humidity were much higher, and the number and group of soil animals in the coniferous and deciduous broad-leaved mixed forest were the lowest. The results of the diversity analysis indicated that the Pielou index (J) and the Shannon-Wiener index (H) of the large-scale soil animals in the evergreen broad-leaved forest were the highest, while the two indexes of the large-scale soil animals in the cold-warm coniferous forest were the lowest; and the Simpson index (C) of the large-scale soil animals in the coniferous and cold-temperature coniferous forest was the highest. [Conclusion] The vegetation type and environment change have a strong effect on the large soil animal community, thus further affecting the soil ecological process.
