长江三峡早期井盐开发的初步探讨

Preliminary Study on Ancient Well-Salt Exploitation in the Three Gorges Region of Yangtze River

采用XRD、SEM和液相包裹体的测试分析方法,具体研究了长江三峡库区忠县中坝遗址出土的花边陶釜及其内壁附着物,证明了中坝遗址出土的花边陶釜是早期制盐容器.结合考古学家的分析研究,表明中国早在西周时期就开始制备井盐,比晋代《华阳国志》记载的我国最早开凿盐井的记录(约公元前255年李冰开广都盐井)大约早790年.

XRD, SEM and liquid inclusion testing were performed on archaeological samples from Zhongba site (round bottomed pottery and deposits on the inner surface). The analysis and results verified that the roundbottomed pottery were ancient Saltproducing vessels. Combined with recent archaeological exploitation and excavation at Zhongba site of Zhongxian County in the Three Gorges region of the Yangtze River (Chongqing Municipality), it suggested that the production of salt from wells and the utilization of their salt can be traced further back to at least West Zhou Dynasty (from 1 046 BC to 770 BC), about 790 years earlier than what Li Bing did('Hua Yang Guo Zhi' written in West Jin Dynasty recorded the event that Li Bing dug up the Guangdu salt well around 255 BC. This is the earliest available record about salt well digging).
