历史时期 ,江苏沿海先民十分重视海塘的修筑。唐宋以前 ,古海塘主要分布在海州湾一带。唐代 ,李承在东冈砂堤上修造了常丰堰。宋代 ,范仲淹又在常丰堰的基础上修筑了范公堤。其后 ,海堤又经多次修筑 ,形成了一道北起庙湾 ,南至吕四的巨大抗潮屏障。江苏古海堤的修筑 ,不但促进了沿海开发 ,而且对现今海堤的修建也具有重要的参考价值。
Historical period, the ancestors of Jiangsu coastal attaches great importance to the construction of the seawall. Before the Tang and Song dynasties, the ancient sea ponds were mainly distributed in the area of Haizhou Bay. In the Tang Dynasty, Li Cheng built Changfeng Weir on the Donggang sand embankment. In the Song Dynasty, Fan Zhongyan again built Fan Gongdi on the basis of Changfeng Weir. Since then, the seawall has been built several times, forming a huge barrier against moisture in the north from Miaowan, south to Lu Si. The construction of the ancient seawall in Jiangsu not only promotes coastal development, but also has an important reference value for the construction of today’s seawalls.
