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
摘要
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=0.4749, df=17, r0.05=0.4555, r＞r0.05; the correlationships between arthropod community and its unnatural enemy sub-community on evenness were significant at 0.01, r=0.8697, df=17, r0.01=0.5751, r＞r0.01; but that on dominance was r=0.1157, df=17, r0.05=0.4555, r＜r0.05. The correlationships between arthropod community and Its natural enemy community on dominance, dominant concentration and evenness were significant at 0.01. The correcting coefficient of the dominance was r=0.7107, df=17, r0.01=0.575, r＞r0.01. The correcting coefficient of the dominant concentration was r=0.8571, df=17, r0.01=0.5751, r＞r0.01 The correcting coefficient of the evenness was r=0.7001, df=17, r0.01=0.575, r＞r0.01.
