摘　　要：概述了黄河第三次调水调沙试验下游泥沙扰动调度实施过程及扰沙效果。通过适时的辅以人工扰动，使扰沙河段断面向窄深方向发展，平滩流量增大，达到了增大主槽过流能力的目的。共扰动泥沙164．13×10^4m^3，调水调沙和人工扰动使扰沙河段平滩流量增加约440～550m^3／s。The agitating and dredging process and its effect in the down stream of Yellow River during the third experiment of regulating water and sediment have been summed up in this paper. With artificial disturbance in proper time during the experiment, the main channel became narrow and deep and the bankfull discharge increased, enlarging the conveyance capacity of the main channel. Nearly 1.64 million m^3 of the bed sediment was removed by agitating and dredging. The regulating water and sediment and artificial agitation dredging made the bankfull discharge increase about 440-550 m^3/s.
