摘要
1997年4月至1999年9月,进行了北麂山列岛岩礁相潮间带贝类的生态调查研究,经整理、鉴定,共得岩相潮间带贝类86种,其中多板类8种,双壳类27种,腹足类51种,主要经济种类21种。本文对其种类组成、定量样本的出现频率、采样断面的种数分布、各断面不同季节不同潮区(站点)的贝类种类、生态特点进行了分析,讨论了以定量样本中的出现频率来作为群落生物优势种的指标。
During April of 1997-Sep., of 1999, we have investigated the Mollusc on the intertidal rocky shore of Beijishan islands off Zhejiang Province. After tidying up and checking up, we get 86 species of rocky shore seashells in intertide zone, thereinto, 8 species belonging to Polyplacophora, 27 species to Bivalvia and 51 species to Gastropoda, about 21 species of which are mostly economy species. In this paper, we have described the species composition, appearance frequency of sample, number distribution of species, and community character. Also discussed the relation between the appearance frequency of sample and the advantage species guideline.
