江苏北部古代海堤与海陆变迁

千余年来，苏北东部沿海为抵御潮患曾先后筑起过三条海堤。随海水东去，现已沦为历史遗迹，但却为研究苏北东部海陆变迁提供了可靠的依据。根据古代海堤的分布位置和兴废时间，分析苏北沿海平原及沿江平原的成陆历史及形成因素，探讨海堤兴废与气温、海面变化等因素的耦合关系。

The Ancient Sea Banks and Changes of Sea and Land in the North Jiangsu Province

Three sea banks were built to protect sea tide in the past more than one thousand years,which provide reliable basis for study of changes of sea and land in the north Jiangsu Province.In the light of the distribution of ancient sea banks and the period of their ups and downs,this paper analyses the formed factors and history of the coastal plain and the riparian plain along the Changjiang River in the north Jiangsu Province,and then also probe into the coupling relationship between the rise and decline of sea banks and the factors such as atmospheric temperature,the change of sea level,etc.
