摘要
采用逻辑质方法研究粉螨在粮食中生态位。分层抽样选取三类粮食的生态位进行逻辑分析。粉螨属与食酪螨孳生在三类粮食中生态位宽有逻辑差异性 ( P>0 .0 5 ,t≤ 2 .41 3;P<0 .0 5 ,t=2 .963) ,同时在粮食中的位重叠也有显著差异 ( P>0 .0 5 ,t≤ 1 .2 2 5 ,P<0 .0 5 ,t≥3.442 ) ,粉螨与食酪螨在三类粮食中倾向独立型孳生 ( X2 =2 .0 4 3,P>0 .0 5 )。并定义了逻辑舟指标。“逻辑舟”
To study ecological niche of the Acaroid mites breeding in grain stocks with the logical and qualitative research.27 species of acaroid mites were isolated from 19 grain species in 3 groups of grain stocks with the stratified sampling.There was significant difference (P>0.05,t ≤2.43;P<0.05,t=2 .963)in niche breadth of Acarus L. and Oudemans, and significant difference (P>0.05,t≤1.255;P<0.05,t ≥3.442) in their niche overlaps;There existed a stronger independence( x 2=2.043,P >0.05) between Acarus L. and Tyrophagus. putrescentiae in 3 groups of grain stocks,While logical china was defined as the relations between ecological niche breadth,overlaps and coefficient of interspecies association.There are different in niche breadth and overlaps,in logically,between Acarus L. and Oudemans;the logical china clarifies the relations between niche breadth,overlaps and coefficient of interspecies association.
