| 中文摘要: |
| 在对2006年7月~2007年10月北黄海4个航次调查资料分析的基础上，对北黄海四季水团进行了基本划分，并将各季水团内的DO及营养盐浓度进行了比较。结果表明，由冬到秋，每个季节北黄海水体由表到底分别可划分为4、7、5、5个水团；其中辽南沿岸水和黄海水团是常年存在的；鸭绿江冲淡水和黄海冷水团于春、夏、秋季存在，冬季消失；渤、黄海混合水团是秋季消失；其他水团则是季节性的存在。在冷水团存续期间，其内部营养盐的浓度均处于较高水平，尤其在秋季，为整个海区的最高值，PO4-P均值高达0-9 μmol/L。 |
| 英文摘要: |
| Based on the four cruises carried out from July 2006 to October 2007 in the northern Yellow Sea(NYS), the water masses in four seasons in the NYS were classified, and the chemical properties in different water masses were discussed according to the temperature and salinity data. Then the nutriment structure in every season in NYS were analyzed. The results showed that the northern Yellow Sea water can be classified into 4,7,5,5 water masses each season；Coastal water in southern Liaoning (Ys1) and Yellow Sea water masses were present all year round; Yalu River freshwater and the Yellow Sea cold water mass（YC）disappeared in winter; Yellow Sea and Bohai Sea mixed water mass disappeared in autumn; Other water masses were seasonally presented. In the duration of the YC, its internal concentration of nutriment was at a high level, especially in fall, with PO4-P up to 0.9 μmol /L. |
