摘　　要：根据2008年廉州湾主要排污口DIN、DIP、COD污染物排放通量,基于FVCOM模式建立了高分辨率的廉州湾三维潮流数值模型及DIN、DIP、COD迁移—转化动力学模型,模拟了廉州湾DIN、DIP、COD污染物浓度分布,模拟结果与2009年6月监测结果进行比较分析,具有较高的一致性。廉州湾生态模型可以较好地模拟出廉州湾的污染物空间分布特征。模拟结果可为廉州湾水质监管、入海污染物总量控制提供科学依据。A high-resolution three-dimensional numerical model of the tide in Lianzhou Bay and a dynamic model of move- ment and transformation of DIN, DIP and COD were established based on the emission flux of DIN, DIP and COD from the major sewage drain outlet and the Finite-volume coastal ocean model （FVCOM）. The pollutant concentrations of DIN, DIP and COD were modeled by the FVCOM. The results of numerical modeling in June 2009 were well consistent with the previously monitoring data. The study shows that the ecological model of Lianzhou Bay could well model the spatial distribution characteristics of the pollutants in Lianzhou Bay. The simulative results provides evidence for the management of marine environment quality and the control of pollutants in Lianzhou Bay.
