本文以安史之乱中新成长起来的中部地区藩镇的演变、及其对整体藩镇格局发展的意义为问题意识，按照时间轴线，讨论唐代中部藩镇的发展线索、朝廷应对藩镇问题时对中部地区藩镇的军事和人事部署，以及相关措施对于解决当时藩镇问题的得失和影响。 安禄山之所以叛乱，是因为唐前期中部地区军事力量空虚。唐王朝应对之方法也是在中部地区迅速组建临时军区，并借此稳住了全国局势，进而平定叛乱。之后中部藩镇仍然作为唐朝重要的军事力量，起着屏障关中、防遏河北、保护漕运的关键作用，维系着唐王朝的政治命脉。这些藩镇不仅在唐代后半期的政治生活中发挥着极其重要的作用，其本身的性格也随着时代的变化发生重大转变，最终演变成五代割据政权。 安史之乱期间，朝廷将军事、财政大权下放给地方，中部地区藩镇的建立自此展开。这一制度调整帮助唐廷迅速平定了叛乱，然而战后，这些下放的权力却由于种种原因未能完全收归中央，中部雄藩的实力愈发强大，埋下动乱的隐患。德宗至宪宗时期，在积累了一定的军事和财政实力后，中央强势出兵，最终掌控了中部藩镇，藩镇格局在元和以后基本稳定。此后，朝廷通过一系列制度改革弱化藩镇，造成中部藩镇力量的坍塌，及至相继发生庞勋、黄巢之变。此时衰弱的藩镇仅能勉力自保，再难拱卫中央。唐朝的灭亡和五代军阀的兴起，都是在中部地区中央军事力量坍塌、权势向新兴军阀（宣武朱全忠、河东李克用）转移下发生的。 以往的藩镇研究乃至唐中后期中央与地方关系的研究，偏重于对河朔藩镇割据的历史考察。本文通过观察中部藩镇发展与演变的历史经纬，认为唐廷能否控制、如何控制中部藩镇，亦可作为理解中晚唐历史发展的一个重要线索。这一另类视角，有助于我们更深刻地认识唐后期藩镇问题的症结所在。

This paper takes the newly growing provinces(藩镇) in the central region and their significance to the development of the whole provincial pattern as the problem consciousness. According to the time axis, this paper discusses the development clues of the central provinces in Tang Dynasty, and the military and personnel deployment of the central government in dealing with local problems. This paper also focuses on the gains and losses of these measures to solve the local problems at that time. The reason why An Lushan(安禄山) rebelled was that the military strength in the central area of Tang Dynasty was weak. The Tang central government's response was to quickly establish many temporary military regions in the central region. By this way, the situation in the whole country was stabilized and the rebellion was put down. After that, the central provinces were still the important military forces of the Tang central government, which played a key role in protecting Guanzhong(关中) area, defending Hebei(河北) area and protecting many canals. They maintained the political lifeline of the Tang Dynasty. These provinces not only played an extremely important role in the political life of the latter half of the Tang Dynasty, but also changed their own characteristics with the changes of the times, and finally evolved into the Five Dynasties. During the An-Shi rebellion, the central government devolved military and economic power to local governments, and the establishment of provinces in the central region started from then on. After the war, these decentralized powers were not completely returned to the central government for various reasons, and the central provinces became more and more powerful, which laid a hidden danger of unrest. From Tang Dezong(德宗) to Tang Xianzong(宪宗), after accumulating certain military and financial strength, the central government dispatched troops to control the central provinces, and the provincial pattern of the whole country was basically stable after Yuanhe(元和). Since then, through a series of institutional reforms, the central government has weakened the local power, resulting in the decline of the central provinces. During the Pang Xun(庞勋) rebellion and the Huang Chao(黄巢) rebellion, the weak central provinces could only protect themselves, not the central government. The fall of the Tang Dynasty and the rise of the Five Dynasties were both caused by the decline of military power in the central region and the transfer of power to new Warlords (Zhu Quanzhong(朱全忠) in Xuanwu and Li Keyong(李克用) in Hedong). The previous studies of the provinces, and even the studies of the relationship between the central and local governments in the late Tang Dynasty, focused on the Hebei provinces mostly. The article, by observing the development and evolution of the provinces in the central region, believes that whether the Tang central government can control and how to control those provinces is also an important view point for us to understand the historical development of the middle and late Tang Dynasty. This alternative perspective may also help us to understand the crux of provinces in the late Tang Dynasty.
