摘　　要：通过对太谷地区枣园害虫天敌群落的系统调查,并应用最优分割法。主分量分析法和1维和2维排序法,探讨了引起枣园害虫和天敌群落演替的主要类群及其演变规律.结果表明,群落具有明显的主导因子和时序演替格局,枣园害虫和天敌群落在前3个主分量上的变动较大,且跟随效应明显;枣园害虫和天敌群落的演替在时间过程中明显分为4个阶段:枣树发芽前、枣树展叶开花期、枣树结果期、枣果着色成熟期;利用主分量分析法,明确了主要害虫及其天敌的种类.Through investigation and by the methods of optimal partitioning, principal component analysis, and one-or twodimensional ordination, this paper analyzed the main groups and succession trends of the pest and natural enemy communities at a jujube orchard of Taigu area. The results showed that the communities had more obvious dominant factors and temporal succession pattern. The first three principal components of the communities had a bigger variation, with an obvious follow effects. The community succession was temporally divided into four stages, i. e., in the periods of pre-budding, leaf expanding and blooming, fruiting, and maturing. The dominant species of pests and their natural enemies were demonstrated.
