从回鹘溃亡扰边看“唐界”与“蕃汉”

Discussions on Tang's Frontier and Sino-Barbarian(Fan-han) Relationship with Reference to the Collapse of the Uighur Empire

唐武宗会昌年间回鹘溃亡扰边一事,为我们细致了解唐朝中后期北部边疆提供了宝贵契机。通过对传世史料和出土文献的爬梳,本文首先考订了会昌年间回鹘溃亡扰边时一些重要地点的方位和事件发生的准确时间。随后以此为基础分析了错子山、鹈泉以及鹈泉处的碛口,分别在防线和边界线两个层面对于维护"唐界"所起的不同作用。最后通过分析晚唐时期北部边疆的兵备、边防以及诸蕃部落的相关情况,论证了晚唐时期边疆地区少数民族势力的发展,并借以管窥此后北部边疆地区沙陀等少数民族崛起的背景。

The collapse of the Uighur Empire and its subsequent disturbance along Tang＇s northern frontier during Huichang Era provided us valuable detailed information about the frontier society.First,by scrutinizing of the related historical and excavated materials,places and time sequence of important events were figured out.Based on these facts,this paper analyzed the various functions of spots including Cuozi Mountain,Piti Fountain and its Qikou（pass）regarding maintaining border of Tang,with the first two serving as a defending line and the last one as a borderline.At last,the development of ethnic groups along the northern frontier during late Tang period was demonstrated by analyzing the its militia,distribution and typical leaders,as a window to show the background of the emergence of ethnic groups including Shatuo as leading powers in this area.
