纪功类碑志文是指将功绩载录于碑石以及其他金石载体上的文章，是碑文中独立的类别之一。本文以中唐时期的纪功类碑志文为研究对象，探究这一文体类型在政治约束下的文本运行机制与书写策略。

第一章线性梳理中唐之前纪功类碑志文的发展脉络，对比分析中唐纪功类碑志文对唐前及初盛唐时期纪功类碑志文的继承和发展。纪功类碑志文发源于秦，定型于汉，完善于魏晋，自诞生伊始便承担着敬祀鬼神、宣示功威、歌颂功德、重构道统等功用，成为确定正统的政治工具。初唐时期，纪功类碑志文因沿袭魏晋骈俪堆饰之风而裹足不前，至陈子昂尚古尚散、张说执掌文坛，浮靡之风一变为清劲爽朗，主散体行文、张实录精神。而李华、韩愈、柳宗元等人则承张、陈余绪，掀起古文运动的风潮，使得碑文内涵更加丰富、行文更加多变、内容更加言之有物。

第二章探究中唐纪功类碑志文写作的时代背景及写作模式的生成。唐王朝在安史之乱的时代背景之下，亟需重建统治秩序、重振帝王权威，纪功类碑志文因其具有能够沟通上下、塑造典型、传达政治思想等种种功用，作为合适的政治工具进入统治者视野。在具体的纪功碑文的撰写中，写作者往往选取“天子”这一隐性主体，与“良臣”“贼佞”这两个显性主体，共同构成天子（统治者）——良臣（执行者）——贼佞（作乱者）的“三种身份”的写作链条。而处于链条中心地位的、作为写作与形象塑造的重点的“良臣”，则必然是基于儒家学说的“仁义之师”或能够“文德教化”俱全的治政良吏。这种以“三种身份”为逻辑连接点、以仁义与德化为核心思想的纪功碑书写模式成为这一时期纪功类碑志文书写的主流模式，甚至形成一种固定的写作机制。

第三章着力于个案研究，第一、二节以中唐复杂政治背景为依托，从帝王与藩王之间的博弈，君臣之间的互动关系入手，探究分析中唐纪功类碑志文的政治话语与书写策略。第三节则围绕权德舆纪功类碑志文书写这一典型个案，探究在政治话语与书写策略的双重驱动下，碑志文中典型人物的塑造及其书写风格的生成。时至中唐，藩镇跋扈，而中央忌惮，双方皆希望通过德政碑的请立与刊树，确定自身的政治地位，谋求更多的政治权益。因此，藩镇德政碑成为两支势力相互拉扯、制衡的凭仗，具备了丰富的文本内涵与政治功用。在具体的纪功碑写作中，写作者着力于构建“忠君明臣”的君臣关系，通过塑造人物典型、树立政治标杆以及使用夸饰、虚饰、裁剪等手法塑造臣子形象，进而在隐形叙述中重张帝王权威，实现政治秩序的重建。

As one of the independent categories of inscriptions, the inscription on inscriptions on steles and other epigraphs refers to the articles that record achievements on inscriptions and other epigraphs. This paper takes the inscription of gongfu in the Middle Tang dynasty as the research object to explore the text operation mechanism and writing strategy of this genre under political constraints.

In the first chapter comb linear development before tang JiGong applied forms, comparison and analysis of Tang Jigong class applied forms to the period before the tang dynasty and the early tang dynasty JiGong class inheritance and development of the applied forms. The inscription of ji Gong originated in The Qin Dynasty, finalized in the Han Dynasty and perfected in the Wei and Jin Dynasties. Since its birth, it has assumed the functions of worshiping ghosts and gods, proclaiming power, eulogizing merit and virtue, and reconstructing Taoism, becoming a political tool to determine orthodoxy. In the early Tang Dynasty, the genre of inscription was held back by the wind of the Parallel Li dui ornaments of the Wei and Jin dynasties. When Chen Zi-ang and Zhang Shuo were in charge of the literary world, the wind of floating mi became clear and vigorous, and the spirit of santi and Zhang Shilu was the main one. Li Hua, Han Yu, Liu Zongyuan and others, following zhang and Chen Yuxu, set off the wave of ancient prose movement, which made the inscriptions richer in connotation, more varied in style and more meaningful in content.

The second chapter explores the historical background and the formation of writing mode of the inscription in the annals of the Middle Tang Dynasty. Under the background of the An and Shi Rebellion, the Tang Dynasty urgently needed to rebuild the ruling order and revive the imperial authority. As a suitable political tool, the inscription on historical records entered the vision of the rulers because of its functions of communicating with the upper and lower levels, shaping models and conveying political thoughts. In the writing of specific inscription on the record of achievements, writers often choose the hidden subject of "Son of Heaven", and the two dominant subjects of "good minister" and "thief and sycophant", which together constitute the
