摘　　要：根据1993年8月所做的芝罘湾环境调查资料，选取底栖生物中的甲壳类、软体动物、棘皮动物、多毛类及其中10个代表种与12项环境因子进行了典型生物种类与环境因子间的多元回归分析，对重金属和石油在生物体的累积以及一些环境污染的指示生物进行讨论，并与该海域历史资料作了对比分析。结果表明，该海域环境因子的变化导致底栖动物群落组成的变化。This paper introduces the work of 'Environmntal impact assessment (phase III) inYantai harbour' in the sea area of Zhifu Bay, Yantai, in 1993. The samples of benthos werecollected using an HNM mud dredger and analysed in laboratory. 87 benthos species were obtainedand the biomass and density of these species were derived. 10 representative species (Lumbrinerislatreilli, Lumbrineris longifolia, Tharyx multifilis, Cirriformia tentaculats, Sabellidae spp, Ophiurakinbergi, fulvia mutica, Macoma praetexta, Mya areaaria, Corophium sp.) of Crustacean, Mollusca,Echinoderm, Polychaeta and 12 benthic environmntal variabes (Eh, Hg, Cu, Pb, Zn, Cd, Cr, Fe,Mn oil, organic matter, sulfide) were considered in the study of the relationship between thebenthos and environmental factors, The stepwise regression equation of the tyPical species and theirhabitat environmnt was estabished. Through these analysis, the principal environmntal factorscontroling the density of some species were identified. The contents of heavy metals and oil in thebody of the three species of Mollusca were also analysed and the concentration factors werecalculatod. At the same time, the indicator organisms of environmntal polution. were discussed.Compared to the investigation data in 1986 about the content of the polutan and the constitution ofthe benthos, we have the following results:(1) The content of the benthic environmntal factors in Zhifu Bay increased dramatically inrecent years with the trend of spreading from the surroundings to the centre of the bay. In particularthe bottom of the harbour pool has been polluted heavily, which is shown by the constitution of thebenthos.(2) The structure of the benthos community has been changed. In 1983, the representativeorganisms were some species of Echinoderm such as Asterias vollestoni, Asterina pectinifera, Luidiaquinaris and the clean warer indicator species Temeoleurus toreumetice. Howeverl in 1993, therepresentative species changed to some pollutant-resistant species of Polychaeta such as Tharyxmultifili
