武则天统治时期的北部边疆,唐王朝正处于从战略进攻转向战略防御、从扩张转向收缩的过渡期,其所制定的北疆政策也必然要适应这种过渡局势的需要,除了北疆少数民族外,内政考虑、吐蕃的威胁等因素也导致武后在北疆一系列重大问题上处置不力,加快了唐王朝在北疆的收缩进程。从武则天时期开始,中原的北疆政策和制度日趋内敛,其侧重点也越来越偏向防务建设。总而言之,武后的北疆政策前接贞观时期全面运用各类政策工具的北疆经略,后启开元时期重在边防的北疆施政,对于有唐一代的北疆带来了深远的影响。 During the reign of Wu Zetian, the northern frontier and the Tang Dynasty were in a transitional period from strategic offensive to strategic defense and from expansion to contraction. The Beijiang policy formulated by them is bound to meet the needs of this transitional situation. Except for the northern minorities The internal considerations and the threats of Tibet also contributed to the weak handling of a series of major issues in northern Xinjiang after the armed forces of Wuchow and accelerated the process of contraction of the Tang Dynasty in northern Xinjiang. From the time of Wu Zetian, Central Plains policies and institutions in the northern part of the country have become less and less restrained. Their emphasis is also increasingly on defense construction. All in all, the policy of northern Xinjiang after the armed forces took the policy of using the various policies and tools in the Zhenguan period and the policy of administering northern Xinjiang focused on frontier defense during the Kaiyuan Yuan Dynasty brought profound influence on the Tang Dynasty’s northern Xinjiang.
