摘　　要：在西大亚湾海域浓度场分布的基础上,用库室模型分析的观点建立了海洋生态系统库室模型,采用浓集因子法建立了相应的线性方程组,对放射性核素在浮游植物、浮游动物、软体动物、甲壳动物、鱼类以及沉积物中的迁移进行数值模拟。数值模拟结果从一定程度上反映了核电站液态排放对海洋生态系统影响的规律。这为预测核电站废水排放对海洋生态系统的影响提供了一套有价值的参考模型及软件。Using Alternating Direction Implicit（ADD method, the numerical simulation of the contamination diffusion in the tide is carried out, and the distribution of concentration field of the western Daya Bay has been achieved. Then a dynamic radionuclide transfer model of ecosystems is constructed on the theoretical basis of compartment model analysis. The numerical simulation result shows the rule of the affection of the radionu clide from the nuclear power station to the ocean ecosystems. So we can use the compartment model of the ecosystems to predict the affections.
