王滩港沿岸是我国发育最典型的砂坝-泻湖海岸之一.本文对王滩海岸的成因、海岸沉积特征、海岸地貌发育及海岸动态等进行了分析探讨.滦河在不同时期、在本区的不同位置入海,为海岸地貌的塑造和滦河三角洲海岸的发育奠定了基础.进入70年代以来,滦河入海泥沙锐减,从而导致本区海岸供沙不足,海岸普遍发生侵蚀,砂坝及滦河新、老三角洲萎缩.若滦河水沙条件无大的变化,王滩海岸的侵蚀过程将会继续,但这种过程是较缓慢的.
The Wangtangang coast is one of the most typical sandbars in China - the coast of the lagoon.This paper analyzes the causes of the Wangtan coast, the sedimentary characteristics of the coast, the development of the coastal landscape and the coast dynamics, etc. At different periods, Since the 1970s, the sediment of the Luan River plunged into the sea, which led to the lack of sand in the coast and erosion on the coast, and the erosion of sand Dams and Luanhe new, the old delta shrunk .If there is no major changes in water and sediment conditions of the Luan River, the erosion process of the Wangtan coast will continue, but this process is relatively slow.
