Abstract: Through investigation and by the methods of optimal partitioning,principal component analysis,and one-or two-dimensional 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.
