唐代吐蕃内侵与河陇语言地理格局的演替

河陇地区,历史上是我国西北地区三大语系的绾结地带,因此不同民族语言之间相互接触与混化的情况司空见惯,但语言演变的具体形式如何,却并不清楚。清理吐蕃内侵所导致的语言地图变化可以发现,多民族杂居的地区,在拥有不同语言的民族政权发生更迭时,会导致该地域民众语言的演变。这种演变的动力在于民众语言与官方语言之间的差异与不同,而演变的方向是民众语言向官方语言看齐。其原因在于官方语言政策的强制性,但演变的速度取决于民众语言的人群规模以及二者之间文化比较优势的大小。

The Tubo's Invasion of the Tang's Territory and the Change of Language Geography in the Hexi and Longyou Region

Historically the three language systems are entangled in the Hexi and Longyou region.Cultural clash and syncretism among different nationalities are widespread.National regimes speaking different languages will speed up the evolvement of their demos language in this region if they succeeds in occupying the region where many nationalities reside mixedly,.The impetus of this evolvement is based on the difference between the demos language and the official language and the orientation of this evolvement from demos language to official language is due to the compulsion of the official language policy.The speed of evolvement rests on the magnitude of the throng speaking the demos language and the comparative cultural predominance between the demos and the official cultures.
