ABSTRACT This article aims to improve the understanding of salt production in the upper Three Gorges region, based on archaeological investigation and excavation of salt-production sites in Yushan, Pengshui County, Chongqing. This article introduces the features of salt sources and the types and dates of the salt wells in Yushan, and investigates the local brine transportation and salt-making techniques. The Zhongjingba site is a large salt-making site with well-preserved remains of production and support facilities dating from the 18th and 19th centuries. Large numbers of evaporation furnaces, brine tanks, and working pits have been excavated and revealed a complete process of producing salt. Analysis of historical documents and the excavated remnants has allowed the reconstruction of the po lu yin zao salt-making process (which, in Chinese, means to splash brine onto the evaporation furnace), the first archaeological evidence of this technique; the management, output capacity, and sales area of the ancient salt production in Yushan are also discussed.

上三峡地区帝制晚期制盐——以重庆中经坝遗址为例

摘要 本文旨在通过对重庆市彭水县玉山产盐遗址的考古调查和发掘，提高对三峡地区产盐的认识。介绍了玉山盐源的特点和盐井的类型和年代，考察了当地的卤水输送和制盐技术。中经坝遗址是一个大型制盐场，其生产和配套设施的遗迹保存完好，其历史可以追溯到 18 和 19 世纪。大量的蒸发炉、盐水罐和工作坑已被挖掘出来，揭示了一个完整的制盐过程。通过对历史文献和出土遗迹的分析，可以重建坡路银枣制盐工艺（用中文来说，意味着将盐水溅到蒸发炉上），这是该技术的第一个考古证据；还讨论了玉山古盐业的管理、产量和销售面积。
