河北天生桥国家地质公园蜘蛛群落及多样性

Spider Community Structure and Diversity of Tianshengqiao National Geopark,Hebei Province,China

2018年8月运用随机扫网、陷阱法和样方相结合的采集方法对河北天生桥国家地质公园蜘蛛种类和群落结构进行了调查,共获得1112头蜘蛛标本,隶属22科54属77种。采用群落多样性指数分析其多样性,结果阐明:天生桥国家地质公园蜘蛛具有丰富的物种多样性,不同植被环境中蜘蛛群落的组成结构有明显差别。灌木丛生境中蜘蛛物种丰富度、个体密度和多样性指数最高,具有稳定的群落结构;阔叶林中蜘蛛均匀度最高;针叶林和草甸中的物种丰富度和个体密度较低,优势度明显。植被保护对保护蜘蛛多样性具有重要意义。

The structure of spider community and species of Tianshengqiao national geopark,Hebei Province,China,was studied in August,2018.With sample,trap and sweep-net together,the author collected spider 1112 individuals,which belong to 22 families,54 genera and 77 species.The result of analysis,by using the community diversity index,shows that spider species diversity in Tianshengqiao national geopark is abundant,and there are some differences of species and structures in different habitats.Shrubs have the highest individual density,species richness and diversity index,with jarless community structure;broad-leaved forests have the highest evenness with less jarless community structure.But coniferous forest and meadows have less species and individual density,with predominant species conspicuous.
