中文摘要：
建立了一个NPZD类型的生物化学模型，并将其与原始方程海流模型（POM）、太阳辐射模型和河流输入模型耦合再现渤海的生态动力过程．模拟的初级生产力与实测值吻合较好；此外，该文还首次全方位地检验了渤海f-ratio的特征，通过与莱州湾的实测值比较，模拟结果也显示了相当的准确度。另外，该文在分析f-ratio变化特征的基础上还揭示硝酸盐和铵盐对渤海浮游植物生长的相对贡献率．
英文摘要：
A NPZD type of ecological model is established to reflect the biochemical process, and further coupled to a primitive equation ocean model, an irradiation model as well as a river discharge model to reproduce ecosystem dynamics in the Bohai Sea. Modeled primary production shows reasonable consistency with observations quantitatively and qualitatively; in addition, f-ratio is examined in detail in the first time, which is also within the range reported in other studies and reveals some meaningful insight into the relative contributions of ammonium and nitrate to the growth of phytoplankton in the Bohai Sea.
