根据白洋淀地理环境的特点，在保持白洋淀基本地理特征和水力特征的前提下，将复杂的淀区水域加以概化，建立水深平均的水动力学方程，通过流体力学的连续方程和动量方程的联合求解，计算出白洋淀的流场，在此基础上。利用二维移流扩散方程进行数值求解，得出白洋淀的污染物浓度场。对于白洋淀各种治理方案的水质做出预测，并提出水污染治理的建议。
According to the characteristics of the geographical environment of Baiyang Lake, while maintaining the basic geographical features and hydraulic characteristics of Baiyangdian, the complex water area of the Dian Lake is generalized, and the hydrodynamic equation of the water depth is established, through the combination of continuous equations and momentum equations of fluid mechanics. Solve and calculate the flow field of Baiyangdian, based on this. Using the two-dimensional flow-diffusion equation for numerical solution, the pollutant concentration field of Baiyang Lake was obtained. Forecasting the water quality of Baiyangdian’s various remediation programs, and putting forward proposals for water pollution control.
