摘要: 对长春市郊区天然次生林、农田、防护林和市区公园绿地等典型土地利用生境进行土壤弹尾虫调查,研究土地利用差异对土壤弹尾虫群落结构的影响。结果表明,长春市土地利用差异对弹尾虫群落结构特征影响明显,地表凋落物移除和耕作活动是影响弹尾虫群落结构特征的主要因素,地表凋落物移除显著减少弹尾虫的个体数量和群落多样性,耕作活动影响弹尾虫个体数量在土体中的垂直分布;地表植物群落类型对土壤弹尾虫群落结构特征也有一定影响。

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.
