摘　　要：研究了有机耕作和常规耕作稻田稻株上部节肢动物群落的12个主要节肢动物类群的种间关系。结果表明:不同的耕作条件下,稻田节肢动物类群及其数量种群存在较大的差异,常规耕作稻田的物种数明显较低,显著相关的种间对的数量明显少于有机耕作稻田。Interspecific association among 12 upper dominant species groups of arthropods were studied between organic rice paddy and normal culture rice paddy. The results revealed that the dominant species and interspecific association of these dominant species were different between organic rice paddy and normal culture rice paddy. In normal culture rice paddy, the richness of dominant species were decreased, and the species couplets number which is strongest correlation were less than in organic rice paddy.
