黄河水量明显减少对下游河流地貌的影响
- Title:
- Geomorphological Effect of Discharge Reduction on the Lower Reaches of the Yellow River
- Keywords:
- discharge reduction; erosion; deposition; channel; river mouth; Yellow River
- 分类号:
- S157;P512.31
- 摘要:
- 分析了黄河下游河床和河口区侵蚀及淤积的变化与黄河水沙变化的关系.黄河水量减少,包括总水量和洪峰水量的减少,会引起下游河床淤积,河口地区淤积减弱,甚至侵蚀后退,也会影响河口以外海岸带泥沙的供给情况,造成黄河三角洲海岸的侵蚀后退.
- Abstract:
- Based on the study the relationship of the erosion/deposition in the lower reaches of the Yellow River and the variation of river discharge,it is concluded that the decrease of the discharge can induce the deposition in the river channel,and sedimentary reduction even retreat of the river mouth.The reduction of sand supply of the Yellow River also can induce erosion along the coasts of the Yellow River delta and retreat of the delta.
