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

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。

The relationships between arthropods community and its unnatural enemy subcommunity 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 subcommunity 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, r 〈 r0.05. The correlationships between arthropod community and its natural enemy community ondominance, dominant concentration and evenness were significant at 0.01. The correcting coefficient of the dominance was r = 0.710 7, df = 17, r0.01 = 0. 575, r 〉 r0.01;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. 7001, dr= 17, r0.01 = 0. 575, r 〉 r0.01.
