摘　　要：研究了有机耕种和常规耕种稻田稻株上部节肢动物群落的12个主要类群的种间协变,结果表明:耕种方式的可影响稻田节肢动物类群种间协变,常规耕种稻田,由于化学药剂的使用,多个种群间的同增同减现象明显,种群间协变性增强,负相关的种对数量明显少于有机耕种稻田。Interspecific covafiant among 12 upper dominant species groups of arthropods were studied between organic rice paddy and normal culture rice paddy. The result revealed that the Interspecific covariant of the dominant species were deeply influenced by the chemical synthetic materials. Lots of the chemical synthetic materials were spray in CK rice paddy, result its interspecific covariant intensity were increased, the number of species couplets which the covariant was negative correlation decreased compared with the organic rice paddy.
