mon 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
