【摘要】 <正>南麂列岛海洋生物种类丰富,区系复杂,近十几年来引起了海洋生物学界的关注。孙建璋等(1976)研究了该岛海域的底栖藻类；陈赛英等(1980)报道了该岛贝类区系；张良兴等(1982)研究了该海域的附着生物和钻孔生物；蔡如星等(1983)在研究浙南岩岸潮间带生态中有对龙船礁的观察；1984—85年浙江省海水养殖研究所曾作过底栖生物调查；1987年中国孢子植物编写委员会组织有关单位联合考察了该岛的底栖藻类,同年浙江省海洋药物资源调查队和上海自然博物馆分别对列岛的海洋药用生物和头足类作了调查。1983年以来作者曾多次赴该岛进行海洋生物采集,1987年还就该列岛潮间带生态学作了一系列的调查和研究,取得了丰富的生态学资料。本文仅介绍岩相潮间带贝类生态学的研究,以供海洋生物学、生态学、动物地理学者及环保、水产部门参考。更多还原

【Abstract】 Nanji Islands,with 23 islets,is situated on the South part of the Zhejiang Coast, (121°05′E,27°28′N).As the abundance of species-composition and complex community structure,Nanji islands are showen solicitude in Allopelagic society.After 1983,we start with investigation and study on rocky mollusca of Nanji islands and in this paper,we summaried the composion and distribution of mollusca species and said that there are 136 species distribute in the intertidal zone of Nanji islands.Also the different virtical distribution in 4 collect local with 3 different ecological standort (Sheltered Inner Mazhu Bay,Exposed Longchuan Reef,and Semi-exposed Outer Mazhu Bay and Dasa Beach) are compared.It is said that the upper limiting factor of virtical distribution on intertidal mollusca is affected by wave and tidal,and the lower limiting factor is by the inter-spe- cific competition for space,disturbance and capture of biological hazard.Beside,the se- quence of the seasonal biomass of organisms is also listed,and comparied the biomass with neighbouring islands on China Sea.更多还原
