提出NPZD类型的海洋水质模型,将模型划分为常参数、浮游植物沉降率时变和浮游植物增长率、浮游动物摄食率、沉降率及浮游生物的死亡率均为时变三种情况.分别利用三种模型对赤潮的发生进行预测.数值仿真验证了模型的正确性.结合特定海域的实测数据进行水质分析与预报,结果证实该模型是可行的.
A NPZD marine water quality model is presented.The model considered three types such as constant parameter,phytoplankton sedimentation rate variant,phytoplankton growing rate and zooplankton ingestion rate and sedimentation and plankton death rate variant.Numerical example and simulation show the effectiveness of the proposed model.The proposed model is tested with real measurement data in certain sea area,which shows that the suggested model is applicable.
