摘　　要：2006年7月对小五台山国家级自然保护区的滩涂、草丛、灌木丛等典型生境的蜘蛛群落结构进行调查,采用样方采集与随机扫网相结合的方法,共采得蜘蛛标本263头,隶属于16科43属55种(属).运用群落多样性指数进行分析,结果表明:滩涂中蜘蛛优势类群较明显,个体密度、物种丰富度和多样性较低;灌木丛和草丛中的蜘蛛优势类群不明显,个体密度、物种丰富度和多样性相对较高.小五台山地区蜘蛛群落结构的现状是种类丰富,优势种不明显,个体数量较少.The structure of spider community in typical habitats （bottomlands, herbages, shrubs） of Xiaowutai Mountain Natural Reserve,China, was studied in July, 2006. With sample and sweep-net together, spider 263 individuals are collected which belong to 16 families, 43 genera and 55 species（genera）. The result of analysis, by using the community diversity index, shows that the predominant spiders in bottomlands are significant, with low individual density, species richness and diversity. The predominant spiders in shrubs and herbages are unconspicuous, with higher individual density, richness and diversity. The actuality of Xiaowutai mountain spider community has abundant diversity, predominant species is unconspicuous, with less individual quantity.
