Spider Community Structure Diversity of Tuoliang Scenic Area,Hebei Province,China

The structure of spider community and species of Tuoliang Scenic Area,Hebei Province,China,was studied in July,2007.With sample and sweep-net together,the author collected spider 983 individuals,which belong to 22 families,60 genera and 84 species.The result of analysis,by using the community diversity index,shows that spider species diversity in Tuoliang Scenic Area is abundant,and there are a few differences of species and structures in different habitats.Shrubs have the most species,highest individual density,with jarless community structure;defoliations have the highest evenness with less jarless community structure.But bottomlands have less species and individual density,with predominant species conspicuous.After analyzing the relations between species and abundance,the conclusion were drawed that the spider community structure in Tuoliang Scenic Area is coincident with Fisher log series distribution,S=34.38 ln(1+N/34.38)(χ2=7.11χ6,0.05=12.59,P0.05).
