摘要： 对扁桃-麦间作果园节肢动物群落与非天敌亚群落、天敌亚群落之间在物种均匀度、优势度和优势集中性上的关系进行相关性分析得出,总群落与非天敌亚群落在优势集中性上相关差异显著,r=0.474 9, df=17时,r0.05=0.455 5,r＞r0.05;均匀度相关差异极显著,r=0.869 7,df=17时,r0.01=0.575 1,r＞r0.01;优势度相关差异不显著,r=0.115 7,df=17时,r0.05=0.455 5,r＜r0.05.而总群落与天敌亚群落在均匀度、优势度和优势集中性上相关差异均为极显著,均匀度相关系数r=0.710 7,df=17时,r0.01=0.575 1,r＞r0.01;优势度相关系数r=0.857 1, df=17时,r0.01=0.575 1,r＞r0.01;优势集中性相关系数r=0.700 1,df=17时,r0.01=0.575 1,r＞r0.01.
