本文从河流动力学的观点出发,分析了历代治河方略与河流中的三对矛盾——水量与河道泄量、水与泥沙、来沙量与河道输沙量的矛盾,考察了我国古代一些有影响的治河方略所反映出来的对三对矛盾的认识程度,在此基础上指出:正确地把握河流中三对矛盾的运动,是制订正确的治河方略的必要条件。 Based on the river dynamics, this paper analyzes the three contradictions in the strategy of governing the river and the rivers in the past dynasties - the contradiction between the amount of water and discharge, water and sediment, sediment and sediment discharge, Based on this, it is pointed out that correctly understanding the three pairs of contradictions in the river is a necessary condition for formulating a correct strategy for water control.
