摘要
根据2008年9月第十二次中韩黄海环境联合调查底栖生物的调查资料整理而成,并与2006年的资料进行比较,分析研究了南黄海海域大型底栖动物的环境质量状况。结果表明,底栖生物种类组成以多毛类居首,软体动物次之。大型底栖生物的栖息密度、生物量和种类数基本上呈现沿岸高,黄海中部低的空间分布特征。调查海域东北部的B3站位是相对稳定的底栖生物栖息密度和生物量高值区。调查海域大型底栖生物可划分为7个群落,以临近长江口的群落Ⅶ的多样性指数和丰富度最高。靠近中国沿岸的群落的生物量组成与临近韩国的群落显著不同。中国与韩国的部分近岸海域均受到一定的人为扰动,但未发现有相互污染的情况。除群落Ⅳ和群落Ⅵ多样性指数和丰富度较低外,其它群落多样性指数和丰富度尚可,群落结构基本稳定。
We analyzed the macrobenthos data of 2008 in the southern Yellow Sea between Korea and China and studied the ecology of macrobenthos. The results show that Polychaeta and Molluscs were the dominant members. The density, biomass and species number were higher in nearshore stations than offshore ones. Seven communities were recognized. The Shannon-Weaver index and richness of them are similar to those of Changjiang （Yangtze） River estuary. The biomass composition was different between China and Korea, and was indicative of pollution in some nearshore areas where biodiversity was the highest. The community structure of the southern Yellow Sea was shown relatively stable.
