扁桃-麦间作果园节肢动物群落与各亚群落之间在均匀度、优势度、优势集中性上的关系

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,rr0.01;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。

The Relationships between Arthropod communitity and Its Sub-communitities on Evenness Dominance and Dominant Concentration in Almond and Wheat Intercropping Orchard

The relationships between arthropods community and its unnatural enemy sub-community and natural enemy sub-community on their dominance,dominant concentration and evenness were analyzed.The results showed that the correlationships between arthropods community and its unnatural enemy sub-community on dominant concentration were significant at 0.05,r=0.474 9,df=17,r0.05=0.455 5,r>r0.05;the correlationships between arthropod community and its unnatural enemy sub-community on evenness were significant at 0.01,r=0.869 7,df=17,r0.01=0.575 1,r>r0.01;but that on dominance was r=0.115 7,df=17,r0.05=0.455 5,rr0.01;The correcting coefficient of the dominant concentration was r=0.857 1,df=17,r0.01=0.575 1,r>r0.01;The correcting coefficient of the evenness was r=0.700 1,df=17,r0.01=0.575,r>r0.01.
