摘　　要：论文通过引入适用于采沙河流的水沙数学控制方程组,确定了珠江河流采沙影响因子—采沙通量Fm,从而建立起珠江采沙河段水沙数学模型。经实测资料检验,结果表明该模型的模拟计算结果与实测结果吻合良好,利用该模型可较好地对珠江采沙河道的演变情况进行模拟。A flow and sediment numerical model adapting to the reach of Pearl River affected by sediment mining activity was established basing on the introduction of a fluvial control equation suitable for this condition and sediment-mining impact factor-sediment mining fluxF,~ of Pearl River. After the comparison of survey data and calculation result, the model was proved to be suitable to simulate the evolution of the reach of Pearl River affected by sediment mining greatly because of the approximation of them.
