【中文摘要】唐元和十三年发生的横海节度使郑权奏管内沧州刺史李宗奭最终致后者获罪身死一 案的历史记载，存在诸多疑点。通过细致爬梳史料可以发现，元和、长庆之际横海管内沧、景二州与德、棣二州发生复杂的建置分合，横海治州亦曾在沧、德二州之间发生移改往复。正是在朝廷力图控制河北的时空背景之下，横海局势的变化与李宗奭的动向才显得如此敏感。将李宗奭案置于宪宗平藩后河北地区微妙的政治关系之中分析，可以揭示朝廷借横海牵制河北的政治意图，以及横海诸节帅借李宗奭案与相关战略部署取信朝廷的政治实态。 【Abstract】There are still a few questionable points in the records about the case that Li Zongshi，Prefect in Cangzhou，was sentenced to death because Zheng Quan，Military Commissioner in Henghai，brought an accusation to the Emperor in the 13th year of Yuanhe. Through painstaking study we can find that there were comprehensive divisions and combinations between Cangzhou，Jingzhou and Dezhou，Dizhou in the province of Henghai，and that the capital of Henghai was moved between Cangzhou and Dezhou during the Yuanhe and Changqing periods. In order to control the area of Hebei the court was so sensible to Henghai and Li Zongshi. Taking the case into consideration on the political conditions in Hebei after Emperor Xianzong put down all rebellions，it was clear that the court tended to restrict Hebei by Henghai，and several Military Commissioners intended to win the court’s confidence through Li Zongshi case and other strategic plans.
