摘　　要：本文以广西龙江河镉污染事件的数据为依据,从重金属镉传播特性角度出发,结合系统动力学理论,率定了重金属镉污染扩散系数,建立了镉污染一维传递模型,探讨了在不同流速下镉在各个监测点之间的传播过程。利用模型预测了洛东电站镉污染物浓度,与实际污染数据对比其R2=0.867,并进行可视化展示。Based on the data of cadmium pollution event in Longjiang river of Guangxi,the diffusion coefficient of heavy metal cadmium pollution was calibrated from the perspective of transmission characteristics of heavy metal cadmium,combined with the theory of system dynamics.The one-dimensional transfer model of cadmium pollution was established,and the transmission process of cadmium between monitoring points at different flow rates was discussed.The model was used to predict the concentration of cadmium pollutants in Luodong power station,and compared with the actual pollution data,the R2=0.867,and the visualization was carried out.
