美国杂交杏李果园害虫与天敌群落种-多度关系分析

Analysis of Species-abundance relation of pests and predators in U.S hybrid apricot and plum orchard

应用对数级数分布模型、对数正态分布模型、几何级数分布模型和分割线段模型对生防美国杏李园、化防美国杏李园、混防美国杏李园、自生普通杏树园、自生普通李树园的害虫和天敌物种相对多度分布格局对比研究结果表明.对数级数分布模型、对数正态分布模型能较好地描述害虫与天敌的多样性。而几何级数分布模型和分割线段模型则不适于该果园害虫与天敌的多样性的拟合。

In this paper,the relative abundance of the Pests and predators was studied by using the patterns of log series distribution,log normal distribution,geometric series distribution,and broken stick model. The groups of U.S hybrid apricot and plum include 3 typies,chemical control garden,biological control garden and mixture control garden,another 2 groups are General Apricot garden and General plum garden.The results show that the relative abundance of the Pests and predators obeys the logarithmic series distribution and the log normal distribution that can be used to describe the the Pests and predators diversity well, and the geometric series distribution and the broken stick model can not be used to describe it.
