摘要: 系统地研究了棉田地面和棉株节肢动物群落及各亚群落施用克无踪(A)、高盖(B)与对照(CK)之间在群落生物多样性、丰富度和均匀度的差异.结果表明,对地面肉食动物群落生物多样性(H′)的A-CK的t值为3.099,B-CK的t值为2.449,tt0.05=2.228,差异显著;地面植食动物亚群落的(H′)A-CK的t值为2.377,A-B为2.260,tt0.05=2.228,差异均显著.棉株节肢动物群落及亚群落A-CK、B-CK和A-B之间差异不显著.地面节肢动物亚群落丰富度A-CK的t值为4.759,地面植食类节肢动物亚群落为4.359,地面肉食节肢动物亚群落为2.963,均tt0.0=2.228,表明A与CK之间差异显著;在均匀度上,A和B及A-CK、B与CK之间两类群落及亚群落上差异均不显著.A和B对棉株节肢动物群落影响很小.施用A和B及CK的生物多样性的变化总趋势一致.

Abstract: This paper studied the differences of the diversity,abundance and evenness of arthropod community and sub community in cotton field among treatments haloxyfor k (A),paraquat (B) and contrast (CK).The results showed that in the diversity of phytophagous sub community, tA-CK =3.099 and tB-CK =2.449 (t>t0.05 =2.228),the difference being significant,and in the diversity of predatory sub community, tA-B =2.260 and tA-CK =2.377 (t>t0.05 =2 228),the difference being also significant.In the arthropod community and sub community,no significant difference was found for A-CK,B-CK and A-B.The abundance of arthropod community tA-CK =4.359,and that of phytophagous sub community tA-CK =2.963,the effect being all significant (t>t0.05 =2 228).No significant difference was found in the evenness of arthropod community and sub community for A B,A CK and B CK.The biodiversity had the same change trend for treatments haloxyfor R (A) paraquat (B) and contrast (CK).
