摘　　要：2013年7—10月,对茂兰喀斯特漏斗森林的大型土壤动物进行研究,共获15 808只,隶属于3门,7纲,20类。选用类群数、个体数及多样性、均匀性、优势度指标来分析土壤动物群落结构。结果表明:茂兰喀斯特漏斗森林生态系统中,优势类群为膜翅目(蚁科)和鞘翅目2类,稀有类群为寡毛类、缨翅目、等翅目、石蛃目、鳞翅目、革翅目6类;优势度方面,海拔最高的样地最大,海拔最低的样地最小;各样地均匀性指数差异不大。From July to October, 2013,the soil macrofauna communities of funnel forest in Maolan karst forest were studied. A total of 15 808 individuals were collected,belonging to 3 phyla,7 classes and 20 orders. The community structure of the soil macrofauna was analyzed with the indicators of community number, individual number and diversity, homogeneity and dominance. Results showed that Hymenoptera and Coleoptera were the predominant groups in the ecosystem system of Maolan karst funnel forest.Rare taxa included Oligochaeta, Isopoda,Thysanaptera, Microeoryphia, lepidoptera and Dermaptera.Dominance of the four sample plots, the plot with the highest altitude got the maximum,and plot with the lowest altitude got the minimum.There were little difference of evenness index in four sample plots.
