| 摘 要： | 在西双版纳热带雨林地区，对３类人工林和１类次生林土壤动物群落结构的时空变化进行了调查。结果表明；蜱螨目和弹尾目在所查４类林地中为常年优势类群；４类林地中，土壤动物类群数和个体数均呈相同的季节消长规律，干热季（４月）〉雨季（８月）〉干凉季（１月），各林地优势类群的种群数量在４月呈现剧增；次生林土壤动物群落类群数，个人本数及多样性在全年高于人工林，林地表层土壤动物拓全年明显多于底层。

| Abstract: | Soil fauna Communities were investigated in three artificial forests and one secondary forest in three seasons, from 1991 to 1992. The composition of groups,distribution of the number of individuals, diversity index of soil fauna were analysed.Results showed that Acarina and Collembola were the dominant community in the four forests in the year round. The seasonal fluctuation of individuals and communities of soil fauna was:April>August>January, and the individuals of soil dominant fauna increased obviously in April. Individuals and their communities on the surface soils were more than those in deep soils. Soil fauna diversity index in different seasons were compared. H'index in secondary forest was higher than that in artificial forests. |
