试说统万城遗址的三重城垣

On the Three-Layered City Wall at the Tongwancheng Site

统万城遗址具有外郭城和东、西城的三重城垣结构,这一认识已在学界达成共识。本文结合历史文献、考古资料及早期影像资料展开讨论,认为统万城遗址西城为大夏国都的主要组成部分;东城的修建年代不晚于隋末;外郭城的年代和性质较为复杂,其东南部可能存在另一独立城址。

The Tongwancheng site consists of an outer wall, a western inner wall and an eastern inner wall. Scholarly consensus refers to this as a triple-wall structure. The author, combining historical documents and material evidence, argues that the western inner wall was a component part of the Daxia capital, while the eastern section could have been founded no later than the final phase of the Sui dynasty. This research also shows that the nature and establishment of the outer wall was more complicated. Another separate settlement might in fact exist near the southeastern section of the outer wall.
