“七国之乱”后吴、淮南二地政区的调整

The Change of Administrative Divisions in Wu Region and Huainan Region after the“Rebellion of the Seven Kingdoms”

“七国之乱”后,汉景帝对吴、淮南两地政区进行了一次全面的调整。在吴地,徙汝南王为江都王,辖东阳郡及原鄣郡的北部数县,将原鄣郡的其余地区和会稽郡合并为新的会稽郡。在淮南地区,徙庐江王为衡山王,割其东南部置为新的庐江郡,将原来江南的庐江、豫章二郡合并为新的豫章郡。这次政区调整既是中央集权政策的重要内容,也是对东南地域政治地理格局的重构。

Emperor Jing of the Han Dynasty adjusted the administrative divisions in Huainan region and Wu region after the“Rebellion of the Seven Kingdoms”.The King of Runan was transfered to be the King of Jiangdu,governing Dongyang Prefecture and the northern counties in the old Zhang Prefecture.The rest of the old Zhang Prefecture was merged with the Kuaiji Prefecture to form the new Kuaiji Prefecture.Similarly,The King of Lujiang became King of Hengshan and the new prefecture of Lujiang was established in the southeast of the old Hengshan kingdom.The original Lujiang south to the Yangtze River was combined with Yuzhang to form the new Yuzhang Prefecture.This adjustment was not only a part of the centralization policy,but also a reconstruction of the political geography in the southeast region.
