摘要：

应用非结构有限体积近岸海流模型FVCOM并耦合美国环保署水质模型WASP对2006年6～8月份的渤海初级生态系统进行了数值模拟和分析研究,模拟的生态、化学要素包括溶解氧、碳生化需氧量、浮游植物、无机磷、有机氮、有机磷、氨氮、硝酸盐和亚硝酸盐。模式考虑了海河、滦河、黄河三条河流的径流输入,计算得到了海区夏季营养盐及浮游植物的空间分布和变化情况,模拟结果表明,本文建立的渤海生态系统动力学模型能够模拟出该季节渤海初级生产系统的基本特征,可为渤海的生态环境保护提供辅助参考。

A finite volume coastal ocean model(FVCOM) was coupled with EPA’s water quality model(WASP) for the Bohai Sea.The study focused on the numerical simulation and analysis of primary production system from June to August in 2006.The simulated biochemical variables include dissolved oxygen,CBOD,phytoplankton biomass,phosphate,organic nitrogen,organic phosphorus,ammonium,nitrate and nitrite.The river runoff of Haihe River,Luanhe River and Yellow River was considered in this paper.The temporal and spatial variation of nutrients and phytoplankton were simulated.The results showed the basic characters of productivity system during the summer in the Bohai Sea and compared the observed data well.
