中唐文学是唐代文学史的重要阶段，在诗歌创作方面呈现出继盛唐以后的又一个高潮，亦被称作唐代文学发展的中兴阶段。洛阳为唐代重要城市，自初唐起便被统治者置作东都，与长安并立。长安和洛阳以双轴心的政治区域成为全国政治、经济以及文化的中心，这便使往来于两都间的文人诗歌创作与地域产生重要关联。尤其洛阳以陪都之特殊地位，其政治功能的强弱直接影响聚集于此的文人诗作。中唐韩孟、元白两大文人群体，其履职经历和诗歌创作便与洛阳城有着密切的联系。 本文以洛阳为中心，按居洛文士集聚现象发生的时间线索划定主要研究范围，即宪宗元和元年（806）至武宗会昌六年（846）。从唐代洛阳城政治层面的职官制度、科举制度，以及城市空间形态与诗歌文学胜景等不同层面，对两大居洛官僚文士群体在特定时空范围内的诗歌创作进行梳理和考察，探究居洛时期官僚文士的政治文化心态对诗风演变和美学风貌形成的影响，力图呈现出动态、细腻、多元、生动的洛阳诗坛盛况，描绘出中唐洛阳城诗歌创作的瑰丽长卷。 全文共分四个章节。第一章主要考察中唐两都视野下东都洛阳城核心功能以及政治制度的演变。重点着眼于元和至会昌时期，东都洛阳的特殊职官制度、科举传统，探究并分析中唐时期的洛阳官僚文士生存的政治空间。第二章则在洛阳城空间形态的视野下考察官僚文士诗歌创作。首先阐释洛阳城地理空间形态的历史嬗变，然后以公共建筑景观以及私人建筑景观两个角度切入，探究官僚文士对洛阳城市景观的情感体验与精神寄托。第三章以居洛两大官僚文士群体的交往与诗歌唱和为主要考察对象，对两大文士群体诗歌交往、创作图景进行考证、梳理和论述。第四章从居洛官僚文士自身角度切入，以孟郊、牛僧孺、李德裕、白居易为典型，探讨洛阳对于居洛官僚文人的人生定位与诗风塑造过程中的重要意义。 本研究尝试回归诗歌创作发生的情境，还原元和至会昌时期两大文士群体的洛阳交往与诗歌创作的盛况，切实探析洛阳城市与中唐文学创作演变之间的联系和规律。研究由以下三方面呈现：第一，明晰了洛阳城整体风貌与中唐文士个体之间的关系；第二，梳理了洛阳城内部空间形态与中唐文士诗歌创作景观之间的互动联系；第三，以个体诗人为例，分析了中唐士人居洛时期的政治文化心态与洛阳易学文化精神之间的内在规律，实现对不同诗人洛居诗歌的创作心态与诗歌多元美学风貌的形成与影响的初步探究。 居洛官僚文士既是政坛显贵，又是文坛领袖，却身处政局混乱党争激烈的时期，政治上无路可走，只能寻求仕途的“退隐”与文学的表达；围绕在官僚文士周围的儒生文士，则胸怀壮志却仕途不畅，命运多舛。洛阳以其突出的地利、文化优势，为官僚文士的集聚以及文学创作提供有利条件，在中唐诗风的发展与形成中具有重要意义。

The literature of Middle Tang has a special significance in the literary and cultural history. It presents as the second prosperous period of poetry in the Tang Dynasty. Luoyang was an important central city in the Tang Dynasty. It was set up by the rulers as the Eastern-Capital in the early Tang Dynasty and stood side by side with the capital Chang-An. Under the guarantee of the two capital systems， Chang-An and Luoyang constitute the biaxial political region with the characteristics of the Tang Dynasty， and at the same time it is also the hub and gathering place of the national economy and culture. There are two representative literary schools in the literature of the Tang Dynasty， namely the Han-Mung Poetry Genre and the Yuan-Bai Poetry Genre. The representative poets of the two factions， Yu Han and Judi Bai， have a close relationship with Luoyang City in the development of poetry creation.

From the political level of the Luoyang City in the Tang Dynasty to the official system， the imperial examination system， the urban space form and the poetry literature， and so on， the two major Jurassic bureaucrats' literary group in the specific time and space of the poetry creation ecology combing and depicting， explore The influence of the political culture mentality of the bureaucrats in the period in Luoyang，on the evolution of poetry style and the formation of aesthetic style， in an attempt to present a dynamic， delicate， diverse and vivid poem of Luoyang poetry， depicting the magnificent scroll of poetry creation in Luoyang City in the middle Tang Dynasty. The full text is divided into four chapters. The first chapter firstly analyzes the ups and downs of Luoyang City in the historical development of the Tang Dynasty from the historical data， focusing on the Yuan He to Hui Chang period， from the special official system of Luoyang， the Eastern Capital， inheriting the tradition of imperial examination， exploring and analyzing the middle Tang The significance of Luoyang City in the period to the bureaucrats. The urban changes in Luoyang discussed in this chapter are divided into stages and briefly summarized. Now from the perspective of the advantages and characteristics of Luoyang City under the historical dimension， the political significance of the city is analyzed from the perspective of bureaucrats. The second chapter focuses on the two creative peaks of Luoyang poetry in the period of 806-846 AD. It corresponds to the formation and development stage of the two bureaucratic scribes group. The focus of this chapter is to create a picture of the two literati groups. Research， combing and discussion. The third chapter puts poetry creation activities into the perspective of Luoyang urban space form， focusing on the poems of private architectural landscapes such as the Shang Yang Palace and other public buildings such as Luoyang Street， and the individuality of poetry creation.

The fourth chapter takes the Yi-style tradition contained in Luoyang's regional culture as the philosophical basis， and analyzes the political and cultural mentality of Bai-Juyi living in Luoyang with "Moderate" and "Harmony"， and then deeply analyzes the cultural mentality of the scholars in the middle Tang Dynasty and the overall aesthetic style of poetry. The potential law between them reflects the interaction between Luoyang City and the development of Literary Creation in the Middle Tang Dynasty. This study attempts to return to the situation of poetry creation， restore the prosperity of Luoyang's communication and poetry creation between the two major literary groups in Yuan He to Hui Chang period， and effectively analyze the connection and law between Luoyang city and the evolution of literary creation in the middle Tang Dynasty. The staged results of the research have the following three aspects: First， clarify the relationship between the overall style of Luoyang City and the individual and the literary traits of the Tang Dynasty; secondly， comb the Luoyang City's internal space form and the landscape of the poetry creation of the Tang Dynasty In the third place， the individual poet is taken as an example to analyze the internal laws between the political and cultural mentality of the scholars in the Jurassic period and the cultural spirit of the Luoyang-living scholars， and to realize the creative mentality and poetic pluralism of the poets of living in Luoyang. Preliminary exploration of the formation and influence of the style. The two official bureaucrats of Luoyang are regarded as an organic whole. The poetry of Luoyang in the middle of the Tang Dynasty presents the characteristics of“flexion and softness， change in it”. Confucian scholars and scribes are often born in the cold， but their ambitions are poor， but their careers are not smooth. The fate of the ancient bureaucrats is both a political dignitary and a literary leader. However， they are in a period of intense political party chaos. There is no way for politics to return to the individual. The expression of life and literature is also the last return to peacefully. Luoyang has a prominent geographical advantage. For Han Men and Confucian scholars， their poems reveal the momentum of "taking the text as a official" and using the influence of the literary world to Chang 'an. For the bureaucrats， they are not only related to the political center. The distance is similar for that of the central officials; the cultural tradition is long， the poetic atmosphere is rich， the identity of the same family is transformed into a good friend， and the literary scholars gather. They are both the world's governors and have a pivotal position and influence in politics. It is also a scholarly scholar who has a rich and versatile aesthetic style， based on the indoctrination and nourishment of Luoyang Ancient-Yin & Yang tradition culture and neutrality thought， based on the yin and yang harmony thoughts. All in all， it has formed a unity of uniqueness and pluralistic symbiosis， seeking new and different and emulating the unity of aesthetics.
