本文利用＂中日黑潮联合调查研究＂的资料探讨营养盐在陆架水域的分布和物理输运的基本特征、形成原因和季节变化过程．研究表明，东海陆架水中的营养盐是冬季沿岸低盐的富营养盐水向东海北部和南部输入并与入侵陆架的黑潮上层低营养盐水混合变性形成的。指出陆架富营养盐水的边界位置随季节变化而有明显的移动规律．叙述了营养盐随沿岸水东扩、和黑潮水北上等过程中的混合扩散和输运规律。
In this paper, we use the data of “Sino-Japanese Kuroshio Study” to explore the distribution of nutrients and the basic characteristics of physical transport, formation reason and seasonal variation of nutrients in the shelf waters. The results show that nutrients in the East China Sea shelf water are formed by mixing low-salt, salt-rich eutrophic saline in the winter coastal areas into the northern and southern East China Sea and mixing with the lower Kuroshio low-nutrient brine on the invaded shelf. It is pointed out that the boundary position of eutrophic brine on the shelf varies obviously with the seasons. Described the nutrient salt with the coastal water eastward expansion, and the Kuroshio northward process of mixed proliferation and transport laws.
