本文扼要分析了黄河下游河道的特点,根据当前防洪治理存在的问题,提出今后的治理对策。作者认为,泥沙对下游防洪的不利影响是多方面的,彻底解决泥沙问题需要综合治理、长期治理。继续兴建干流水库控制洪水泥沙,可以迅速改善下游宽河道冲淤变化剧烈的不利局面,延缓河道继续淤积抬高,显著削减下游洪水。配合其他措施,保持下游河道百年内外稳定和安全是可能的。
This article briefly analyzes the characteristics of the lower reaches of the Yellow River, according to the current problems in flood control, put forward future governance measures. The author believes that the adverse effects of sediment on flood control in downstream areas are various. To completely solve the sediment problem requires comprehensive management and long-term governance. Continuing to build the mainstream reservoirs to control flood and sediment can rapidly improve the unfavorable situation of drastic changes in the erosion and deposition of downstream wide channels, delay the continued deposition and elevation of the channels, and significantly reduce downstream floods. In conjunction with other measures, it is possible to maintain the stability and safety of downstream rivers within and without a hundred years.
