楼兰简纸文书西晋纪年中断始末

自曹魏以来,楼兰文书一直行用中原纪年,却于晋武帝泰始六年(270)中断。根据楼兰简纸文书、元康三年(293)苻信简等出土资料,结合传世文献,作者认为学界已有树机能叛乱使纪年中断的观点恐不能成立,苻信简透露出西部鲜卑南下滋扰,西晋为此采取了收缩政策。张轨刺凉后,彻底肃清了河西寇乱,重建了楼兰的屯戍,楼兰文书得以再现西晋正朔。

On the Interruption of Using the Western Jin Reign Title to Number Years in Loulan Documents

Since the Cao Wei(曹魏)period,using the Central Plain reign title to number years had been found in Loulan Documents.But it was interrupted from the sixth year of Taishi(泰始)in the Western Jin Dynasty.According to Loulan documents,the sealed letter of the third year of Yuankang(元康),combined with the traditional historic books,the author believes that the view held by historian that Shujineng rebellion caused the disruption can't be established.The sealed letter reveals that due to the west Xianbei(鲜卑)'intrusion in the border area,the West Jin Dynasty took a retreating policy.After Zhanggui(张轨)was appointed Liangzhou governor,he quieted the riots in Hexi region,and re-built the garrison land cultivation system in Loulan,so the Western Jin reign title appeared again in LouLan Documents.
