摘要：Zhan，Q.;王，L.;詹，C.; Cui，B.;刘，X.;李，X.;王，X.; Yu，X.，和Zhang，J.，2020.公元1128 - 1855年黄河入侵期间淮河口的地貌动力演变。In：Zheng，C.W.;王，Q.; Zhan，C.，和Yang，S.B.（编辑），海上和极地丝绸之路的海气相互作用和海岸环境。《海洋研究杂志》，特刊第99期，页。250-256.椰子溪（佛罗里达），ISSN 0749-0208。根据历史记载，研究了黄河入侵时期淮河口的动力条件、地貌特征及演变机制。结果表明，公元1128年至1855年，由于大量含沙径流进入黄河，淮河的径流量和输沙量增加。但不同时期的输沙量也受到黄河下游沿着反复淤积的影响。淮河口是一个中等强度的潮汐河口。其往复潮流和沿岸流体系有利于沉积物入海。淮河入海口的形状是上窄下宽。河口内、外分别发育大型拦门沙和水下三角洲。河口河道为典型的弯曲河型，世纪以来河口宽度有增大趋势。淮河河口的演变机制是潮流界限不断向下游移动，河口不断向大海延伸。此外，潮流界向下游移动的距离远大于同期河口向外延伸的距离，导致河口断面明显缩短。为满足径流和潮流对能量的需求，河口段河型呈曲流型，口门加宽。古淮河口与现代黄河口具有不同的动力地貌特征和演变机制，不能简单类比。
ABSTRACT Wang, Q.; Zhan, Q.; Wang, L.; Zhan, C.; Cui, B.; Liu, X.; Li, X.; Wang, X.; Yu, X., and Zhang, J., 2020. Morphodynamic evolution of the Huaihe River estuary during the Huanghe River invasion from 1128 AD to 1855 AD. In: Zheng, C.W.; Wang, Q.; Zhan, C., and Yang, S.B. (eds.), Air-Sea Interaction and Coastal Environments of the Maritime and Polar Silk Roads. Journal of Coastal Research, Special Issue No. 99, pp. 250–256. Coconut Creek (Florida), ISSN 0749-0208. Based on historical records, we investigated the dynamic conditions, geomorphological characteristics, and evolution mechanisms of the Huaihe River estuary during the period of Yellow River invasion. The results showed that the runoff and sediment discharge of the Huaihe River increased owing to a large quantity of sediment-laden runoff into the Yellow River from 1128 to 1855 CE. However, the sediment discharge in different periods is also affected by repeated siltation along the lower reaches of the Yellow River. Huaihe estuary is a tidal estuary with moderate intensity. Its reciprocating tidal current and coastal current system are favorable to the discharge of sediment into the sea. The shape of the Huaihe estuary is narrow on the upper side and wide on the lower side. Large-scale sandbar and underwater delta were developed in the inside and outside of the estuary, respectively. The channel of the estuary has a typical curved river type, and the width of the estuary has had an increasing trend since the 18th century. The evolution mechanism of the Huaihe estuary is that the tidal current limit continuously moves downstream, and the estuary continuously extends to the sea. In addition, the downstream movement distance of the tidal current limit is much longer than that of the outward extension of the estuary during the same period, resulting in a significant shortening of the estuary section. To satisfy the energy demand by runoff and tidal current, the river type of the estuary section becomes meandering and the entrance is widened. The ancient Huaihe River estuary and the modern Yellow River estuary have different dynamic geomorphological characteristics and evolution mechanisms, which cannot be simply analogized.
