摘　　要：胶州湾底栖生物组成复杂,数量丰富,其中有些种为捕捞对象,如菲律宾蛤仔等开发潜力很大,有些种为鱼、虾类天然饵料,如多毛类的长吻沙蚕、索沙蚕,软体动物的金星碟铰蛤等。底栖生物对渔业资源的补充和开发利用以及增、养殖和海洋生态学的研究都具有重要意义。早在30年代,张玺教授等(1936)This paper presents results of study on the species composition, distribution of biomass, density and communities of the macrobenthic infauna in Jiaozhou Bay using materials collected during May 1991-February 1994 at 10 stations.200 species of macrobenthos were collected: Polychaeta 78 species; Crustacea 57 species; Mollusca 40 species; Echinodermata 11 species; and 14 other species. The average total biomass was 71.9g/m2. The biomass of Polychaeta, Crustacea, Mollusca and Echinodermata were respectively 5.4 g/m2, 2.9 g/m2, 44.9 g/m2 and 12.4g/m2. The average total density was 132.0 ind./m2. The density of Polychaeta, Crustacea, Mollusca and Echinodermata were respectively 46.8 ind./m2, 27.5 ind./m2, 33.1 ind./m2 and 6.3 ind./m2. The biomass maximum (131.4 g/m2) occured in spring, the minimum (33.8 g/m2) in winter. The biomass in autumn and summer was 72.1 g/m2 and 42.1 g/m2 respectively. The highest (148.6 ind./m2) density occurred in summer, the lowest (86 ind./m2) in autumn. The density in winter and spring was 136.2 ind./m2 and 130.8 ind./m2 respectively.
