摘    要:根据黄海、东海的最新现场调查资料,探讨了长江口及其邻近海域营养盐分布特征与输送途径.调查结果表明,在长江口以东及其东北部海域终年存在一个范围很大的营养盐高值区.分析表明,这些营养盐主要来自长江冲淡水的扩展及苏北沿岸流的输送.此外,还获得了1998年长江流域特大洪水期间,迄今被观测到的长江冲淡水中营养盐的最大扩展范围.

关 键 词:营养盐    平面分布    输送途径    长江口    黄海、东海

Abstract:This paper discusses the distributions and transportation of nutrients in the Changjiang River Estuary and its adjacent sea areas, based on the data obtained during field observations in the Yellow Sea and the East China Sea. It is pointed out that there are abundant in nutrients in the area of the east and northern-east of the Changjiang River Estuary in all the season of a year. It is believed that the nutrients come from the extension of the Changjiang River diluted water and the transportation of the Subei Coastal Water. Besides, the maximum extension range of the nutrients of the Changjiang River Diluted Water was observed during the period of super flood in the Changjiang River drainage area during summer, 1998. It is of significance for the studies of the influences of the Changjiang River Diluted Water on the biogeochemical processes and the marine environment of the Huanghai Sea and the East China Sea.
Keywords:nutrient  horizontal distribution  transportation  the Changjiang River mouth  the Huanghai Sea  the East China Sea
