摘要
1996年8月中旬,在张家口地区4种生境中共捕获土壤蜘蛛461头,隶属于12科54种(属)。研究表明:4种生境中的土壤蜘蛛群落相似性很小,群落结构组成不同,丰富度、多样性指数、均匀度、优势度也不同。植被类型、疏密程度是影响群落结构的主要生态因子,农事活动是另一个重要影响因素。
There are no reports of ecological research on the structure and diversity of soil spider communities in Zhangjiakou region ,Hebei. In August, 1996,461 spiders were collected in four different habitats. They belong to 54 genera (species), 12 families. There is little similarity among the four spider communities in four habitats. Species diversity (H'),species richness (S),eveness (E),dominant concentration (C) of spider communities are different among them. The composition of species and number are different,too. The main factors which result in the difference are analyzed.
