摘　　要：为研究低浓度杀虫剂对土壤动物群落结构的影响,采用野外定点方法进行三种典型杀虫剂的喷施实验,对中小型土壤动物群落结构进行分析。结果表明低浓度杀虫剂使中小型土壤动物个体数和类群数减少,但减少幅度不大,低浓度杀虫剂对不同动物类群影响不同,使蜱螨目和弹尾目数量减少,鞘翅目和膜翅目蚂蚁数量增多;低浓度杀虫剂处理对土壤动物群落多样性指数影响不大,对群落垂直方向的表聚性影响也不明显。In order to study the effect of low concentration pesticides on soil fauna community structure, three typical kinds of pesticides were sprayed in field to analysis the meso soil fauna structure. The results show that spaying low concentration pesticides reduce the individuals and groups of meso soil fauna, but the decrease range is not large. The effects on different animal groups of low concentrations pesticides are different, such as reducing Acarina and Collembola while increasing Coleoptera and Hymenoptera individual number. The effects of low concentration pesticides on meso soil fauna diversity and vertical structure are all not obvious.
