摘　　要：分析和探讨了东海黑潮区海水无机氮的分布特征成因机制.结果表明,春、秋季陆架区表层无机氮测值较高,黑潮主干为低值区,深层则相反.深层氮的分布与溶解氧、水温及密度相吻合,等值线走向与黑潮流轴完全一致.春、秋季底层氮与Aou呈正相关,与水温呈负相关,表明其含量变化主要依赖于生化过程.Based on the observation data collected in Kuroshio Current and the East China Sea in spring and autumn 1988, the distributional characteristics and the cause of formation of inorganic nitrogen in the current and the sea have been studied. In surface the concentration of nitrogen is higher in the area over continental shelf in spring and autumn, but lower in the mainstream area of the current; while in depth the status is on the contrary. The distrbution of the inorganic nitrogen is identical with that of dissolved oxygen, temperature and density. The isopo-tential of inorganic nitrogen is coincident with the mainstream. In spring and autumn, inorganic nitrogen in depth is a positive correlativity with Aou but a negative one with temperature. This shows that the changes of concentration of inorganic nitrogen depend mainly of biological process.
