在宋太平兴国七年(982)党项拓跋部首领李继迁叛宋重建夏州政权前,党项拓跋部世次嬗递是不清楚的。吴天墀曾在其《西夏史稿》中列过《西夏拓跋氏世系表》,1周伟洲先生在他的《唐代党项》一书中亦列出过《唐五代拓跋部李氏世系表》。2此二表不仅断层很多,而且出现不少错误。邓辉、白庆元先生在《唐研究》第八卷发表的论文《内蒙古乌审旗发现的五代至北宋夏州拓跋部李氏家族墓志铭考释》,其中亦列《夏州拓跋李氏世系表》,3虽然此表多依据考古材料而成,但仍出现错误。2005 It was unclear how the party chieftain and chieftain of the party’s affairs had been handed down before the reestablishment of the Xia State regime by Li Jigui, the leader of the Party’s Tuoba Department during the Song and Taiping rejuvenation of the country for seven years (982). Wu Tien-chi had listed “the Western Xia and Tuoba lineages” in his “History of the Western Xia Dynasty”. In his book “Party Items in the Tang Dynasty”, Mr. Zhou Weizhou also listed the “Li Clan Tables in the Tuoba Department of the Tang and Five Dynasties” . 2 The two tables not only have many faults, but also show many mistakes. Deng Hui and Bai Qingyuan’s essay “The Study of the Epitaph of the Li Clan of Li Clan in Tuoba of Northern Xia Dynasty from Five Dynasties to Northern Song Dynasty” published in the eighth volume of “Tang Studies”, which also listed “Li Zhou Tuoba Epoch Table ”, 3 Although this table mostly based on archaeological materials, but still errors. 2005
