浦东是明代成化年间黄浦水系最终定型后形成的一个相对独立的地理单元。明中叶以后,由于盐课的折银以及荡地的扩张,使浦东地区盐业生产逐渐退居次要地位。随着盐区的转移和扩展,民、灶等不同身份的人群争夺资源不断升级。从清浦场裁撤一案,可以清晰地看出荡地被大量开垦成田并种植经济作物的趋势,不仅严重挤压了盐场和灶户的生存空间,而且直接导致盐场管理权的转移。 Pudong is a relatively independent geography unit formed after the final setting of the Huangpu River system in the Ming Dynasty. Since the middle of Ming Dynasty, salt production in the Pudong area has gradually taken a back seat to secondary status due to the folding of silver in salt courses and the expansion of land clearing. With the transfer and expansion of the salt areas, people, stoves and other people with different identities compete for resources to escalate. The abolition of the case from Qingpu Field clearly shows that the trend of extensive land reclamation into cash crops and economic crops not only severely squeezed the living space of the saltworks and stoves, but also directly led to the transfer of management rights in the saltworks.
