苏北古海堤考证

A VERIFICATI0N 0F ANCIENT DIKES lN NORTH JIANGSU AREA

苏北海岸线长达953.9km。历史时期,沿海先民十分重视海堤的修筑。唐宋以前的海堤主要分布在海州湾一带。唐代,李承在古砂堤(东冈)上修建了常丰堰。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,形成了一条北起庙湾,南至吕四的巨大抗潮屏障。苏北古海堤的修筑,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 coastline of North Jiangsu is 953.9 kilometres in Length .During its- historical period, the ancients in the coastal area put great stress on the con- struction of dikes.Before the Tang and Song Dynasties, dikes were mainly scat- tered in Hai Zhou Bay area. In the Tang Dynasty, Lichen built Changfeng Dike on offshore bar (East Sand ridge).During the Song Dynasty,Fan Zhong- yan constructed Fangong Dike on the base of Changfeng Dike. Having been reconstructed many times afterwards, it became a huge defence against tides, running from Miaowan in the north to Lusi in the scuth. 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.
