论魏晋南北朝食盐产地

魏晋南北朝有食盐产地82处。其中，海盐产地19处、池盐产地26处、井盐产地28处、土盐产地3处、石盐产地6处。与秦汉时期相比，增加了27处。在长达360余年的时间里，这个变化难以称道。可见，魏晋南北朝时期食盐产地发展速度比较缓慢。其中变化较大的是井盐产地明显增加，而且出现了6处石盐产地。之所以出现这种局面，主要有以下原因：（一）分裂割据严重影响了盐业生产；（二）西南地区相对安定的社会秩序有利于盐业生产的发展；（三）西域地区社会发展促进了食盐资源的开发。总之，这个时期食盐产地的发展主要是西部地区。这种局面的形成与这个时期西部地区社会发展密切相关。

On Salt Production Sites in Wei, Jin, and Southern and Northern Dynasties

In the period of Wei, Jin, and Southern and Northern Dynasties, there were 82 salt production sites, among which 19 are for sea salt production, 26 for lake salt production, 28 for well salt production, 3 for soil salt production and 6 for rock salt production. Compared with that in Qin and Han Dynasties, 27 salt production sites were added, which was a very slow increase during more than 360 years. So, salt production sites developed at a relatively slow speed in that period. Among them, a significant increase appeared in well salt production site and 6 soil salt production sites were established. Such phenomena can mainly be attributed to the following reasons： 1） separatist regimes seriously influenced salt production; 2） relatively stable social order in the southwest area was beneficial to salt production; 3） social development in western region promoted the development of salt resources. In short, major development of salt production site then was in western region, which was closely related to its social development.
