创建相对稳定的黄河三角洲海岸

To Shape Relatively Stable Coast of the Yellow River Delta

黄河三角洲是淤泥质海岸,其稳定性很差。在以往研究的基础上,分析了海岸的不稳定特征及其产生的不利影响,提出参照沙质岬角海岸的稳定平衡模式,合理安排稳定的黄河入海流路,控制河口海岸沙嘴长度,采用逐级平衡法,创建相对稳定的黄河三角洲海岸形态。

The Yellow River delta is a silty coast with a poor stability. On the basis of the previous research results, the authors analyzed the fea- tures of the unstable coast and resultant unfavorable influences. With these, the authors proposed that the Yellow River deltic coast can be gradually made to have a relatively stable form by following head-land control, reasonable arranging of the stable estuarine course, control of the river mouth sandspit length and using stey-by-step equilibrium method.
