| 摘 要： | 海洋浮游植物对海水硒的富集系数为228,表明硒是一种生物亲合力很强的元素。在真光层中,75％的硒为海洋生物所利用,显示硒在海洋环境是中等生物制约元素。28％的含硒生物颗粒沉溶解在深层水体,导致硒在表层水中消和浑水中富集,类似于营养盐。利用Broeeker双箱模式计算,粗略地显示了硒在大洋中的循环图象,初步确立各界面硒的通量。

| Abstract: | The Se enrichment facter by marine Phytoplankton was estimated to be 228, it suggests that Se is a pretty strong biophile element. About 75% of Se in the eutroPhic layer is utilized by phytoPlankton, it means that Se is a bio-intermediate element in the ocean About 28% of Se biogenic Particles fall into the deep ocean where most of them will redissoved then, and it leads a qvcr srtical like nutrients, A Se two-box modle following Broeker S was cstabli-hd and Se fluxes between the ocean interfaces were roughly worked out, |
