明清时期苏北沿海荡地涨圮对盐垦业及税收的影响——以南通、盐城地区为例

North Jiangsu coastal marsh land's influence on salt reclamation and tax in the Ming and Qing dynasties-focus on Nantong City and Yancheng City

荡地是明清时期苏北沿海制盐业与垦殖业的基础。沿海荡地为煎盐提供了燃料,也便于就近取用海水,盐产量与荡地的多寡有直接联系。随着海岸线东迁以及淡水冲刷,原有荡地盐碱含量逐渐降低,垦殖业具备了发展条件。明清时期,荡地淤涨或圮坍对苏北盐业、垦殖业以及税收有很大影响。

Marsh land formed the basis for the salt production and reclamation in the north Jiangsu coastal areas in the Ming and Qing dynasties. The coastal marsh provided the fuel for decocting salt, supplied convenient sea water, hence a close relationship between the salt yield and the availability of marshes. As a result of the eastward movement of the coast and fresh water sluicing, the content of salt in former marshes reduced, which prepared the salt reclamation industry to develop. During the Ming and Qing dynasties the rising and fall of coastal marshes exerted great influences on the salt industry, reclamation and tax.
