黄河口三角洲演变及其反馈影响的研究

Study on evolution of the Yellow River delta and its reactions[KH*2

本文对黄河三角洲演变机理进行了探讨。作者采用实测资料分析了河口冲淤的反馈影响，并运用数学模型计算了河口向海域延伸的安全距离。在现有的控制条件下，黄河口溯源淤积的范围一般在利津附近，溯源冲刷的范围在刘家园以下。

The mechanism of the Yellow River delta was discussed in this paper. Based on the measured data and calculation with mathematical model, the reactions of the river mouth evolution on the upstream river channel were also depicted. Under the existing control conditions, the retrogressive deposition can extend to Lijing, and the retrogressive erosion is generally located in the reach below Liujiayuan.
