历史时期江苏古海塘的修筑及演变

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。

The Structions and Changes of Ancient Dikes in Jiangsu Area during Historical period

During historical periods,the ancients in Jiangsu coastal area put great stress on the construction of dikes.Before Tang and Song Dynasties,dikes were mainly scattered in Hai Zhou Bay area.In Tang Dynasty,Licheng built Changfeng Dike on East Sand ridge.During Song Dynasty,Fan Zhongyan constructed Fangong Dike on the base of Changfeng Dike. Having been rescontructed many times afterwards,it became a huge defence against tides,running from Miaowan in the north to Lusi in the south.The construction of the ancient dikes in North Jiangsu has not only promoted exploitation along the coast but also offered an important reference to the modern construction of dikes.
