苏北平原的捍海堰与淮南盐场历史地理考

The Breakwater on North-Jiangsu Plain and a Historical and Geographical Exploration of Huainan Salt Field

北宋范仲淹在苏北平原修建了捍海堰,阻挡了海水对苏北平原的侵袭,使得堤内土地得到开发。但是对于两淮的盐业生产来说,捍海堰阻断了盐场的海水来源,使得盐灶的生产受到影响。通过对宋代以后淮南盐场和捍海堰的相对地理位置考证,可以发现,宋代捍海堰建立之后,盐灶就已经搬迁到捍海堰东部,而非学界所认为的盐场在明代以后才东迁。明代以后,随着海陆变迁的加剧,盐场生产的盐灶都分布在远离捍海堰的沿海滩涂之上。

In the Northern Song Dynasty,Fan Zhongyan built a breakwater on North-Jiangsu Plain in order to protect it from sea water.However,the breakwater might affect the salt production in this area.Historical and geographical exploration finds that the salt workshop was moved away in the Song Dynasty after the breakwater was built.This conclusion goes against the common academic belief that the salt field was moved east after the Ming Dynasty.
