吐蕃向西域的开拓

Tubo's Expansion to the West

吐蕃统一青藏高原后,积极地向东和向北开拓自己的疆域,在北方主要是与唐王朝对西域的博弈。安史之乱后,吐蕃在西域的角逐中完全占据了上风,并且切断了唐朝与西域的交通线。公元791年后,西域东南部完全被吐蕃统治,长达近百年之久。为了在西域的争夺中占据主动权和统治这一地区,吐蕃在西域开辟了很多条便捷的交通线,本文就其中几条重要交通线进行论述。

After unifying Qinghai-Tibet Plateau,Tubo continues to expand eastward and northward.To the North,its major challenge comes from the attempt of Tang to control the Western Regions.After An Lushan Rebellion,Tubo seizes the superiority in the scramble,cutting off Tang's transportation line to the Western Region.Since 791 AD,the Southeast of the Western Region has been dominated by Tubo for one hundred years.In order to seize the superiority in the Western Region and maintain its dominance in this area,Tubo opens up several convenient transportation lines and a few of them are studied in this paper.
