摘　　要：[目的]探明韭山保护区潮间带底栖生物种类组成和数量分布,为保护区管理提供基础资料。[方法]根据韭山列岛的地理位置,设置3个调查站位,于2016年8月进行取样调查。[结果]共鉴定潮间带生物78种,优势种有短滨螺(Littorina brevicula)、粒结节滨螺(Nodilittorina exigua)、日本菊花螺(Siphonaria japonia)、嫁虫戚(Cellana toreuma)、史氏背尖贝(Notoacmea schrencki)等;潮间带生物量密度平均为2 544.0 g/m2,个体密度平均为21 623.9个/m2;从3个站位的生物种类数分布来看,由多到少依次为积谷山、大青山和南韭山,生物量密度由高到低依次为大青山、积谷山和南韭山,个体密度由高到低依次为积谷山、大青山和南韭山。[结论]该研究为今后保护效果评价提供参考依据。[Objective] The research aims to identify the composition and distribution of benthic organisms in the intertidal zone of Jiushan Islands, and to provide scientific information for the reserve management. [Method] Biological samplings were conducted at three sites in Jiushan Islands in August 2016. [Result] In total, 78 species of intertidal organisms were identified. Littorina brevicula,Nodilittorina exigua, Siphonaria japonica, Cellana toreuma, Notoacmea schrencki etc . were recognized as the dominant species. The average biomass-density was 2 544.0 g/m^2, and the average density was 21 623.9 ind./m^2. The Jigushan had the highest richness of species and highest density of individual, followed by Daqingshan and Nanjiushan. For biomass density, the Daqingshan ranks the highest, followed by Jigushan and Nanjiushan.[Conclusion] This study provides a reference for future evaluation of protection effects.
