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。

摘  要：
[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 was2 544.0 g/m2,and the average density was 21 623.9 ind./m2. 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.
