本文根据1987年10-11月“实验3”号考察船在西太平洋赤道海区的调查资料,阐述了Cu,Pb,Zn,Cd等金属元素和PO_4-P及SiO_3-Si等营养元素在微层中含量及公布和富集作用。六种元素的含量都是微层高于表层。它们的分布都是近岸向远岸递降。它们在微层中都有富集作用,但富集度有明显差别。Zn,Pb,Cd,Cu,PO_4-P和SiO_3-Si的平均富集因子分别为60.6,22.4,8.3,3.3,1.7和6.5。
Based on the investigation data of “Experiment 3” survey ship in the equatorial Pacific Ocean from October to November, 1987, this paper describes the effect of metal elements such as Cu, Pb, Zn and Cd and PO_4-P and SiO_3- In content and publish and enrich the role. The content of the six elements are micro-layer above the surface. Their distribution is nearshore descent to the far shore. They are enriched in the micro-layer, but there are significant differences in enrichment. The average enrichment factors for Zn, Pb, Cd, Cu, PO 4 -P and SiO 3 -Si are 60.6, 22.4, 8.3, 3.3, 1.7 and 6.5, respectively.
