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
