古代镇江,一直就是沟通大江南北的要冲。无论春秋时代的朱方、秦代的丹徒、三国的京口,西津渡都是当时的军事重地和交通要津。隋唐以后,朝廷打压六朝古都的南京,贬为县级,镇江却升为润州,再由于南北大运河的修通,镇江地位日显重要。在漫长的岁月里,它曾是我国东南地区漕粮、丝绸等物质北运京师的重要港口。 Ancient Zhenjiang, has always been the hub of communication north and south. No matter Zhufang in the Spring and Autumn Period, Dantu in the Qin Dynasty, Jingkou in the Three Kingdoms, or Xijindu are both important military areas and transportation areas at that time. After the Sui and Tang dynasties, the court suppressed Nanjing, the capital of the Six Dynasties, and relegated it to the county level. However, Zhenjiang was promoted to Runzhou. As a result of the repair of the North-South Grand Canal, the status of Zhenjiang became increasingly important. In the long years, it was once an important port of the North Yunjing Capital of grain and silk in the southeast region of our country.
