摘要
根据1988年7月和11月东山湾潮间带4个断面获得的多毛类样品,研究了多毛类的种类组成、数量分布及其与底质的关系等生态特点。共鉴定多毛类91种,以暖水性广盐种占优势;平均生物量力2.54g/m^2,平均栖息密度为30个/m^2;多毛类种类和数量的分布很不均匀,底质是影响多毛类生态特征的重要环境因素。
Based on the data obtained from four sections of intertidal zone in Dongshan Bay in July and November, 1988, the present paper studies the ecological characteristics of the species composition, the quantitative distribution of Polychaeta and the relationship between sediments and Polychaeta. 91 species, mainly warm water euryhaline species, were identified. The average biomass and density were 2.54g/m2 and 30 ind./m2 respectively. The spatial distributions of species and individuls were extremely uneven. Sediment was an important factor which influenced the ecological characteristics of Polychaeta,
