吐谷浑是两晋南北朝时期兴起于西北地区的少数民族。这一民族自东晋南北朝一直绵延至唐宋,近七个世纪之久。这样一个民族,值得治史者重视。笔者主要从吐谷浑民族的形成、其与周邻的关系、民族迁徙及“吐谷浑之路”以及“白兰”的研究四个方面对其进行了一定的研究。 Tuyuhun is a minority nationality rising from northwest China during the Southern and Northern Dynasties. This nation has been extending from the Eastern Jin and Southern and Northern Dynasties to the Tang and Song dynasties for nearly seven centuries. Such a nation, it is worth the attention of the historian. The author mainly studies the formation of Tuyuhu nationality, its relations with the neighboring countries, national migration and the road of Tuyuhunhun and the research of Bailan.
