试论古代云南政区地名的第一次大变迁

On the first major change in the geographical names of administrative districts in ancient Yunnan

云南的政区地名始于西汉中期,此后一直处在不断的演变过程中。汉代至魏晋南北朝,其大体上呈延续发展的情形,相对稳定而又逐渐变化,各朝代相对于前代都有数量不等的一些增减,改易也时有发生。隋至唐前期,一种基本上是全新的政区格局经两个王朝前后相继的积极经营而建立起来,从而诞生了一个新的政区地名组群,将云南政区地名的发展史带入了一个新的时代。唐代以来的政区地名在这一阶段经历了整体性的、大幅度的更迭。导致这一次大变迁的原因,一是云南各地部族分化状况的较大变化,二是羁縻政区制在云南地区的普遍推行,三是隋唐政区层级制的变革。

The geographical names of administrative districts in Yunnan emerged in the middle of the Western Han Dynasty,and they had been in the process of continuous evolution since then until the Wei,Jin,Southern and Northern dynasties.Each dynasty saw some changes in the geographical names with some new ones emerging and some old ones disappearing.The period from the Sui Dynasty to the early Tang Dynasty saw the establishment of an almost new pattern of administrative districts through the active operation of the two dynasties,which produced a new group of geographical names for administrative districts in Yunnan and indicated a new era for the geographical names of administrative districts in Yunnan.In this period the geographical names of the administrative districts in Yunnan experienced a holistic and substantial change,whose causes were as follows:relatively conspicuous changes in the tribal differentiation in various parts of Yunnan;the overall implementation of the control policy for the administrative districts in Yunnan;the reform of the hierarchical system of the Sui and Tang dynasties.
