摘　　要：本文对西双版纳热带雨林地区的３种不同类型人工群落林中的旱季（４月）土壤动物的种类组成和数量分布及土壤动物群落的多样性、均匀性、优势度和相似性进行了分析比较。蜱螨目和弹尾目是这３种人工群落林中土壤动物优势类群。土壤动物的垂直分布特点是表层多于底层，表聚现象明显。胶茶林土壤动物群落丰富度和个体数量最高，半人工次生林多样性和均匀性最好，优势度以人工多层林最高。Soil animal communities were investigated in three different man-made plant communities in dry season (April), 1991 Species composition, the number of individuals, the dominance, evenness, diversity and similarity coefficient of soil animal communities were analysed The results showed that Acarina and Collembola were the dominants in the three plots The character of vertical distribution of soil animals was that the individuals and spieces of soil animal on the ground are more than those in the soil The rubber-tea community had the highest both in species and individual numbers The secondary forest showed the highest diversity and evenness The highest dominance occured in the man-made community with multi-layer structure The similarity coefficient between the soil animal communities in the man-made with multi-layer community and the secondary forest is the highest one
