摘要
历史时期黄河下游河道演变规律表明，河流从沿程淤积到河口延伸、再到溯源淤积的自适应过程，在1000a、100a、50a、10a等各种时间尺度上均可能发生，这对淮河水系改造的可行性论证、方案设计等有重要指导意义。
The channel evolution law of lower reaches of the Yellow River inhistorical time indicates that the channel self-adapting process from downward silting toriver mouth stretching and then backward silting may occur in a time scale of 1000yr,100yr, 50yr or 10yr. The results of this study are of great importance to considerationof river system improvement of Huaihe River in the future.
