孙吴西晋南岭政治地理格局的变迁——以政区边界调整为中心

The Changes of Political Geography Pattern of Nanling in Sun Wu and Western Jin Period——Centered on the Adjustments of Administrative Regional Boundaries

秦汉时代南岭地区的政区边界以“犬牙相入”状态为主。进入六朝以后,孙吴政权对南岭政区进行了两次大规模调整,新置的始兴、临贺、始安三郡皆北隶荆州,分别从南岭东、中、西三面嵌入岭南的核心区域,荆州与交广之间出现了“单向嵌入”式的边界形态。西晋平吴后,南岭三郡南隶广州,形成了广州反向嵌入岭北的新态势,至西晋末年三郡再度北隶湘州。以荆湘制交广的思路基本被东晋南朝所继承。孙吴西晋时代南岭政区的数度调整,均与各时期特定的政治地理格局相联系,反映了王朝南方边地治理的需要。

In the Qin and Han dynasties,the administrative boundary of Nanling region mainly showed the state of“Quanyaxiangru”(犬牙相入)and changed greatly after the period of Six dynasties.The Sun Wu regime made two large-scale adjustments of administrative regions on Nanling.The newly established counties included Shixing(始兴),Linhe(临贺)and Shian(始安)were subordinated to Jingzhou(荆州),which embedded into the core areas of Lingnan from the east,middle and west of Nanling respectively.It came into being the boundary form named“Danxiangqianru”(单向嵌入)between Jingzhou and Jiaozhou(交州)as well as Guangzhou(广州).After Western Jin conquered Sun Wu,the three counties of Nanling were subordinated to Guangzhou,forming a new state that was Guangzhou inversely embedded in the Five Ridges.In the late Western Jin Dynasty,the three counties were subordinated to Xiangzhou(湘州).Afterward,the idea that restricted Jiaozhou and Guangzhou by Jingzhou and Xiangzhou was inherited by the Eastern Jin Dynasty and Southern dynasties.The several adjustments of administrative regions of Nanling in Sun Wu and Western Jin Dynasties were related to the specific geopolitical pattern of each period,reflecting the needs of the governance of the southern frontiers of the dynasties.
