在唐后期的历次削藩战争中,元和削藩无疑最为成功,影响也最大。而元和削藩诸战争中又以淮西战争(815—817年)的胜利最具战略意义,它对成就宪宗“元和中兴”产生了重要影响。学界一直以来对淮西战争关注颇深,在战争的背景(动因)、基本过程、影响与意义;裴度与李想等人的功绩评判;韩愈、段文昌《平淮西碑》相关问题等方面,都做了比较深入的探讨,并且不乏远见卓识。本文将依次对以上诸方面的研究成果进行梳理,尽可能集中反映元和淮西战争的研究状况。 During the last tribal wars in the late Tang Dynasty, Yuanhejianfan was undoubtedly the most successful and influential. However, the victory of the Huai Xi War (815-817) between the Yuan and Ch’ien-fei Wars was the most strategic and had an important impact on the success of the constitutional “Yuan and ZTE”. The academia has been paying close attention to the war in the Huaihe River for a long time, and its background (motivation), basic process, influence and significance in the war; Pei Duo and Li Xiang et al.’s merits judgment; Han Yu and Duan Wenchang “Ping Huai West Monument” and other related issues Aspects, have done a more in-depth discussion, and there is no lack of foresight. This article will, in turn, sort out the above research results and concentrate as much as possible on the research status of Yuan and Huaixi wars.
