Abstract: This paper investigated the soil collembolan in Changchun City in July and September 2003,with the focus on the species richness and abundance under farmland,park greenbelt,protective plantation forest,and natural secondary forest.The results showed that land-use type had a significant effect on the community structure of soil collembolan,and litter removal and farming activities were the main affecting factors.Litter removal considerably decreased the individual density and community diversity of soil collembolan,while farming activities changed the vertical distribution of collembolan individuals in soil profile.The types of aboveground vegetation also had a significant effect on the community structure of soil collembolan.
