初步探讨了东海营养盐的分布,给出了不同层次的营养盐锋区,既可以作为区分水系的指标,又给出了不同水系的化学特征和运移的方向。初步研究结果与从水文学角度研究成果的基本分类相吻合。营养盐的断面分布表明化学要素的垂直方向结构,给出了化学要素跃层在不同海区的顶界和底界。特别是对黑潮主干区的黑潮表层水、次表层水、中层水和深层水的划分较为清晰。黑潮主干区化学要素间的相互关系表明黑潮水的大洋水特征。
The nutrient salt distribution in the East China Sea was initially discussed, and the nutrient salt front areas at different levels were given, which can not only serve as an index to distinguish the water system, but also provide the chemical characteristics and migration directions of different water systems. The preliminary results are in good agreement with the basic classification of the results of the study from hydrological perspectives. The cross-sectional distribution of nutrients shows the vertical structure of the chemical elements and gives the top and bottom boundaries of the chemical elements in different sea areas. Especially, the division of surface water, subsurface water, middle layer water and deep layer water of the Kuroshio current in the Kuroshio area is clearer. The correlation between the chemical elements of the Kuroshio Scenario indicates the oceanic water characteristics of the Kuroshio.
