黄河下游纵横剖面调整规律的研究对下游河道的治理和中上游水库的调水调沙运用有着重要的意义，本文根据实测资料，分析了１８５５年以来不同时期黄河下游纵剖面调整过程及１９５０年以来不同水沙条件下黄河下游纵横剖面调整规律，从理论上探讨了纵剖面调整的机理，使我们对这一问题在认识上达到了一个新的阶段。
The regulation of vertical and horizontal profile regulation in the lower Yellow River plays an important role in harnessing the lower reaches of the Yellow River and regulating the use of water and sediment in the middle and upper reaches of the Yellow River. Based on the measured data, this paper analyzes the vertical profile adjustment process of the lower Yellow River at different periods since 1855, Under different water and sediment conditions, the regulation of vertical and horizontal profiles of the lower Yellow River reaches the theoretical level and discusses the mechanism of longitudinal profile adjustment, so that we reach a new stage in our understanding of this issue.
