　　Abstrust　The soil arthropod communities in 6 different tea plantations of Si mao were inve stigated in 1996.10031 individuals of soil arthropod were collected,which belong to 4 classes ,21 orders.The dominant groups were Acarina and Collembo la, The co mmon groups were Symphyla Coleoptera Hymenoptera.The groups and individuals of s oil arthropod community increased with the contents of soil organic matter and t otal N,and it decreased with soil depth.The curve of diversity index was simila r to the curve of evenness of soil arthropod community. The production activity affected diversity of soil arthropod community to a certain extent.
　　Key words　Tea plantation, soil arthropod, community struct ure, soil environment

　　思茅山区位于云南西南部，22°02′～24°50′N、99°09′～102°19′E，为低纬度高原季风气候区，年降雨量1580mm，年均温18℃～20℃；干湿季分明。为探索土壤节肢动物的群落特征与茶园土壤环境的关系，提高茶园土壤肥力，建设高产、高效、优质生态茶园，我们对云南思茅茶园土壤节肢动物进行了调查研究。
