摘要
作者提出1985.8—1986.7月长江口南岸底栖动物种类组成、污生生态、群落特征和长江口南岸水、底泥和生物中重金属含量,并以污生生态特征和重金属分布特征对该区污染状况作出评价。本文还就各断面的优势类群、多样性指数、生物重金属含量与污染源的关系及长江口南岸底栖动物的污生生态指标种和重金属污染指标种进行了讨论。
The paper reports the results of studies on the species composition, saprobiotif ecology and characteristics of zoobenthos community and content of heavy metals in sampls of water, mud and organisms in the south coast of the Yangtze River estuary, and an evaluation of pollution by using the characteristics of the saprobiotic ecology of the zoobenthos and the distribution of the heavy metals from August 1985 to July 1986.Dominant zoobenthos groups, index of species diversity, the relationship between the content of heavy metals in organisms an the pollution source and indicator species of the saprobiotic ecology and the pollution of the heavy metals in the seven sections of the region are also discussed.
