初唐正史修撰中对东北民族认识源于魏晋史料的积累。通过梳理文献,以初唐为分界线总结其前后的差异规律,厘出其后对东北民族定位变化是缘于唐宋之际民族大融合与中原王朝整体战略调整的共同结果。 The understanding of northeast nationalities in the early Tang Dynasty during the reorganization and prose compilation originated from the accumulation of historical materials in Wei and Jin Dynasties. By combing the literature and summarizing the differences between before and after the Tang dynasty as the dividing line, it is concluded that the subsequent orientation to the ethnic groups in Northeast China is due to the common result of national integration and the overall strategic adjustment of the Central Plains during the Tang and Song dynasties.
