会昌伐叛后泽州隶属问题小考
The Clarification of Zechou’s Affiliation after Suppressing the Rebellion during Huichang

唐武宗于会昌四年(844年)讨平刘稹后，根据“犬牙交入”的政区划分原则，将昭义军所属之泽州划归河阳节度使管辖。由于与潞州在地理、行政、风俗文化等方面的高度关联性，泽州最终于唐昭宗天复元年(901年)复隶潞州昭义军。史料关于泽州隶属军镇的记载相当矛盾，重新厘清唐朝藩镇所领州县的变动时间与缘由能进一步完善唐代行政区划研究，也有助于深化中晚唐朝藩关系的认识。
After subduing Liu Zhen in the fourth year of Huichang (844), Emperor Wuzong of Tang shift the jurisdiction of Zechou from Zhaoyi town to Heyang town, according to the indented principle of dividing administrative divisions. Due to the high correlations between Zechou and Luchou in terms of geography, administration, customs, culture and so on, Zechou would eventually return back to the jurisdiction of Zhaoyi town which govern center was Luchou in the first year of Tianfu (901). However, the records about Zechou’s affiliation are quite contradictory. Reclarifying the timing and reasons for administrative changes is helpful to improve the study of administrative divisions in Tang Dynasty and deepen the understanding of the relationship between the vassal and central government in the late Tang Dynasty.
