摘　　要：应用潮波方程和扩散方程计算出放射性核素110mAg在大亚湾的浓度分布,使用库室模型描述海洋生态系统动力学微分方程组,建立了海洋生物库室简化模型,得出大亚湾海域马尾藻对放射性核素110mAg的迁移转化在各网格处达到动态平衡时的浓度规律.模拟结果与实测数据基本一致,说明模型的建立及参数的选取是恰当的.该方法为预测核电站废水排放中放射性核素的对海洋生物的影响提供了科学依据.The concentration of radionuclide ^110mAg in Daya Bay is computed by tidal wave and diffusion equations. A simplified ocean - biology compartment model is set up through dynamics differential equations of ocean ecosystem. Then the concentration is computed through this model when ^110mAg reached its dynamic balance in every grids. The numerical simulation results are in agreement with the observation data. So the foundation for predicting the affection of radionuclide from nuclear power station to aquatic ecosystem is provided.
