利用废黄河的历史记载和野外资料,研究了1194～1855年间明清故道的淤积形态和纵剖面的调整过程.研究表明,调整过程大致可以分成两个阶段.第一阶段调整河道纵剖面以适应黄河中游的大量来沙.第二阶段则随着河道延伸整个河道纵剖面抬高.河道延伸和河床抬高之间具有明显的关系.河道延伸的溯源影响可以上溯很远. 现今黄河的纵剖面形态和废黄河十分相似,近40年来变化很少,说明现今黄河下游可能也已进入第二阶段,河口延伸已成为河道持续堆积的主要原因.因此,必须减少进入河口地区的泥沙,才能从根本上解决黄河下游的问题.
Based on the historical records and field data of the waste Yellow River, the sedimentation morphology and longitudinal profile adjustment process of the Ming and Qing Dynasties were studied from 1194 to 1855. The study shows that the adjustment process can be roughly divided into two stages: the first stage is to adjust the river longitudinal profile to adapt to In the middle reaches of the Yellow River, a large amount of sand comes in. In the second stage, the river profile extends along the longitudinal profile of the entire river, and there is a clear relationship between river channel extension and river bed elevation. The morphology and waste Yellow River is very similar, little change in the past 40 years, indicating that now the lower Yellow River may have entered the second phase, the river mouth extension has become the main reason for the continued accumulation of rivers. Therefore, we must reduce the sediment into the estuary area, To solve the problem of the lower reaches of the Yellow River fundamentally.
