胶州湾氮、磷浓度的三维数值模拟

Three Dimensional Numerical Simulation of Nitrogen and Phosphorus Concentrations in the Jiaozhou Bay

考虑了近岸海域影响氮、磷含量、时空分布的主要物理、生物化学过程,建立了胶州湾海域非保守物质(氮、磷)的水质预测模型。模型将氮、磷及与其相关的浮游植物、浮游动物作为状态变量,模拟了胶州湾海域夏季各状态变量浓度的时空分布。结果表明胶州湾北部氮、磷浓度最高,湾中央及湾口海域水质较好,各变量垂向分布均匀。数值模拟结果与监测结果及历史资料较为符合。

A water quality model of non-conservat.ive substances, including nitrogen, phosphorus, phytoplankton and zooplankton is established, which takes into consideration the physical and biochemical processes related to nitrogen and phosphorus. The temporal and spatial variations of each stable variable in Jiaozhou Bay for summer 2001 is simulated. The results show that the concentrations of nitrogen, and phosphorus are the highest in the north of Jiaozhou Bay and there is little difference vertically. A comparison between the calculation results and the observation data indicates that the model is satisfactory.
