唐代边疆史地属于唐史研究领域中资料难度比较大的课题,但是近二年以来,情况发生了很大的改观。晚近新发现的大量汉文墓志中不仅许为边疆少数族人墓志,即使汉人墓志也不乏涉及边疆史地内容的记载。比之下,当前从事边疆史地研究,在取材方面大大超出了前辈学者能够猎的范围。将新发现的史料,特别是新发现的汉文墓志资料与汉文传统献的记载结合起来,不仅可以为边疆史地研究增添新的资料,而且它本应该也是边疆史地研究的一个新的发展方向。本文针对唐代正史缺载, The historical land in the frontier of the Tang Dynasty belongs to the subject with relatively difficult data in the field of research on the history of the Tang Dynasty. However, the situation has undergone great changes in the past two years. The recent discovery of a large number of Chinese epitaphs not only for the frontiers of minority epitaphs, even if there is no lack of Chinese epitaphs related to the history of borderland records. In contrast, the current research on the history and geography of the borderlands has far exceeded the scope of the scholar of the predecessor in terms of drawing material. Combining the newly discovered historical materials, especially the newly discovered Chinese epitaphs with the traditional Chinese records, not only adds new information to the study of the frontier history and geography, but it should also be a new direction for the study of the history and geography of the border areas . This essay aims at the lack of official history in Tang Dynasty,
