摘要
北海南部湾(the Southern Bight of the North Sea)6个站位取样鉴定了13个小型底栖动物类群。其中线虫Nematoda、底栖桡足类Copepoda、涡虫Turbellaria、多毛类Polychaeta和水螅Hydrozoa在各站均有发现。线虫与桡足类丰度比率R为1.2～30.7。701站和435站以较低的类群组成和多样性指标、以较高的R比率而明显区别于其它各站。分析结果表明:该两个站位小型底栖群落结构除了沉积物类型因素外,巳受到污染的严重影响。比利时沿岸701站的污染源来自Western Scheldt河长年携带大量工业废物和生活污水的入侵,而435站则归因于TiO_2废物的倾倒活动。
A total of 13 meiofaunal taxa were identified from the samples from 6 stations in the Southern Bight of the North Sea in spring 1985. Five of the taxa, Nematoda, Copepoda, Turbellaria, Polychaeta and Hydrozoa, were found at all 6 stations. R, or the ratio of Nematoda to Copepoda (N:C), varied from 1.2 to 30.7. Station 701 and 435 were clearly distin-quished from the others in lower taxonic diversity and higher R value. The results were used for ecological monitoring environmental quality of the area. It was concluded that the meiobenthic communities in station 701 and 435 had been influenced by heavy pollution. The sources of the pollutes, for station701, were imputed to the huge industrial wastes and sewage carried by river Western Scheldt, and for station 435, to the TiO2 waste-dumping.
