1987年3月至1988年12月笔者在九龙江口及厦门西海域调查结果表明九龙江口与厦门西海域无机氮含量较高,分别为28.25和18.76μmol/L,NO_3-N是该海域氮的主要存在状态,NH_4-N也是较重要的形态。九龙江溶解无机氮入海通量估算为6千吨/年。氮的循环、转化对于维持厦门西海域生产力水平有重要的作用。NO_3-N、NO_2-N、NH_4-N分布的季节变化主要是受生物活动的影响。
From March 1987 to December 1988, the survey results of the authors in the Jiulongjiang Estuary and Xiamen Western Seas showed that the inorganic nitrogen contents of Jiulongjiangkou and Xiamen western seas were higher at 28.25 and 18.76μmol / L, respectively. NO3-N was the main nitrogen in the area Existing state, NH_4-N is also more important form. Jiulongjiang dissolved inorganic nitrogen into the sea flux is estimated at 6,000 tons / year. Nitrogen circulation and transformation play an important role in maintaining the productivity of the west coast of Xiamen. The seasonal changes of NO_3-N, NO_2-N and NH_4-N are mainly affected by biological activities.
