河陇民族格局重构影响下的晚唐政府对吐蕃政策

Late Tang Dynasty's Tubo Policy under the Influence of Ethnic Structure Reconstruction in Helong Region

9世纪中叶,河陇民族格局随着吐蕃统治的崩溃出现了新变化,各方势力纷纷参与到西北政治格局中。面对新的政治形势,晚唐政府及时调整西北战略部署,对吐蕃政策成为西北战略的重要组成部分,并受到周边势力,尤其是党项的牵制,从而影响到以后中原王朝的西北政策。

In mid 9th century, ethnic structure in Helong region displayed new changes in wake of the collapse of Tubo ruling; various powers got involved in political structure in northwest region. Under such new political situation, late Tang dynasty governments adjusted their strategic deployment, and made Tubo policy a key part of northwest strategy. They were pinned down by surrounding powers, especially Dangxiang power; and this influenced the northwest policies of late central dynasties.
