| 摘 要： | 基于宁波-舟山海域潮流场,建立了该海域三维变边界的污染物扩散模型,对COD、无机氮、活性磷酸盐的浓度进行了数值模拟,并对界面源的影响进行了分析。结果表明:污染物浓度在海域内呈由西北向东南方向递减的趋势;COD浓度在大部分海域满足一类水质标准,无机氮和活性磷酸盐浓度在研究海域超出二类水质标准;研究海域的界面源对该海域污染物浓度”贡献”在85%以上。

| Abstract: | Based on the tidal current of Ningbo-Zhoushan sea area,a three-dimensional variable boundary diffusion model was built.The concentration of COD,inorganic nitrogen and active phosphorus was simulated.The effect of boundary resource was analyzed.The results showed that the concentration of the pollutants declined from northwest to southeast.The concentration of the inorganic nitrogen and active phosphorus was above the second water quality.The boundary resource had a proportion of 85% to the pollutant distribution. |
