唐宋时期,在西南地区政权长期鼎立对峙和内外意识增强的背景下,西南区域民族地理观出现了重大变化。唐代中后期,初步形成了“巴蜀内地汉族区—沿边民族地区—徼外蛮夷地区”的三重格局民族地理观。两宋时期,沿袭了三重格局的民族地理观,认识更为完整和系统,并且发生了一些变化。 In the Tang and Song dynasties, with the long-term confrontation between the southwestern regimes and the increasing awareness both internally and externally, significant changes have taken place in ethnic ethnography in the southwestern region. In the middle and later period of the Tang Dynasty, the tri-dimensional national geography of the “Han area in the hinterland of the hinterland of Sichuan, the minority areas along the border and the barbarians in the border areas” was initially formed. During the Song and Song dynasties, the national geography of the triple pattern was followed, the understanding was more complete and systematic, and some changes took place.
