陆源污染物对海州湾环境影响研究

应用沿深平均二维模型模拟海州湾水域的潮流场，分析该水域的潮波运动规律，计算不同风条件下海州湾水域的Lagrange余流场，分析风时对余流的影响，以海州湾顶的临洪口为陆源污染源，用数值方法求解物质扩散方程，分析在不同风条件下湾内污染物平均浓度随的变化，在保证污染物排放总量不变的情况下，对不同排放方式下湾内污染物的平均浓度进行了比较。

Impacts of land pollution sources on Haizhou Bay environment

On the basis of the depth-averaged 2-D tidal model, the tidal regime of the Haizhou Bay is studied. The influences of different wind conditions on the Lagrange residual flow are analyzed. With Linhongkou as a land pollution source, the variation of average pollutant concentration at the bay with time is studied according to the depth-averaged 2-D dispersion equation. Under the assumption of a constant volume of pollutants discharged, the average pollutant concentrations at the bay under different discharge modes are compared.
