摘　　要：根据1985-1987年期间19个月份的断面调查资料分析,莱州湾?渤海湾是硝酸盐氮浓度较高的海域,辽东湾?渤海湾是亚硝酸盐氮浓度较高的海域?硝酸盐氮浓度冬季最高,夏季最低;亚硝酸盐氮浓度秋季最高,春季最低?硝酸盐氮浓度的季节变化在莱州湾?渤海湾海域最大;亚硝酸盐氮浓度的季节变化在辽东湾最大?在分析海域,秋季平均硝酸盐氮浓度表?底层差异最大;夏季平均亚硝酸盐氮浓度表?底层差异最大?海洋生物化学过程是引起渤海硝酸盐氮和亚硝酸盐氮浓度季节变化的主要原因?渤海硝酸盐氮和亚硝酸盐氮基本维持着准平衡态季节循环,底层硝酸盐氮和亚硝酸盐氮准平衡态季节循环比较稳定,表层的季节循环容易受到其他因素的影响发生变异?During 1985-1987, the concentration of nitrate nitrogen was higher in the Laizhou Bay and Bohai Bay, the concentration of nitrite nitrogen was higher in the Liaodong Bay and Bohai Bay. The concentration of nitrate nitrogen was highest in winter and lowest in summer. The concentration of nitrite nitrogen was highest in autumn and lowest in spring. The seasonal variation of concentration of nitrate nitrogen was maximum in the Laizhou Bay and Bohai Bay. The seasonal variation of concentration of nitrite nitrogen was maximum in the Laodong Bay. The concentration of nitrate nitrogen had a great difference between surface and bottom in autumn, and the concentration of nitrite nitrogen had a great difference between surface and bottom in summer. The main reason for the nitrate nitrogen and nitrite nitrogen seasonal cycle was the marine biochemistry process. The quasi-equilibrium state seasonal cycle of the nitrate nitrogen and nitrite nitrogen was kept in the Bohai Sea.
