淮南地区粉螨群落结构及其多样性

Community structure and diversity of acaroid mite in South Anhui Province

在淮南地区仓储、人居、工作、野外4类生境中采集粉螨样本,行分离、镜检,共检获粉螨3 650头,隶属于7科20属,共32种。结果表明,其物种数S、丰富度指数R、多样性指数H′排序均为仓储环境>野外环境>人居环境>工作环境,野外环境中粉螨群落的均匀度指数最大,工作环境中粉螨的优势度指数最大。工作和野外环境的群落相似性指数最低,达到极度不相似水平。结果表明,粉螨群落的结构及多样性与其生境条件直接相关,人类活动是较为重要的影响因素。

To study the community structure and diversity of acaroid mite in South Anhui Province,samples from four different habitats were collected,isolated and identified.A total of 3650 acaroid mites were detected,belonging to 7 families,20 genera and 32 species.Diversity analysis showed that the species number S,species richness index R,and species diversity index H′ of acaroid mite in the habitats were in the order of warehouse>external environment>human habitat>work environment.The species evenness index J′ of ...
