| 摘 要： | 根据黄、渤海无机氮的收支状况，首次提出了黄、渤海无机氮的稳态收支模式。模式研究结果表明，大气沉降、陆源输入和海底输入的无机氮通量分别占黄、渤海无机氮浮游植物总需求量的3%、4%和12%。无机氮的外部输入约占总需求量的1/5，其他部分则由水柱中的内部再循环（再生）供给。

| Abstract: | Based on the estimation of the fluxes in the biogeochemical cycling of inorganic nitrogen, a steady-state nitrogen budget model was put forward for the Bohai Sea and Yellow Sea in this paper. Model studies indicated that the atmospheric input, riverine input and benthic flux of inorganic nitrogen account for 3, 4 and 12 percent of nitrogen requirement by phytoplankton (NRP) in the Bohai Sea and Yellow Sea, respectively. Inorganic nitrogen supplied from the three major external sources, i.e. atmosphere, river and benthic flux, accounts for one-fifth of NRP, the other part of NRP is satisfied through the regeneration in the water column. |
