位于北京天安门广场东侧的东交民巷近代历史地段形成于二十世纪初。地段内的近代建筑以使馆为主体，兼有银行、洋行、教堂、医院等建筑，风格体现了当时盛行于欧洲的折衷主义，是北京近代建筑史中浓墨重彩的一笔。本文通过对大量历史资料的调查研究，深入挖掘了东交民巷近代历史地段的演变过程，分析了使馆建筑群的形成、建筑类型、艺术风格，并对东交民巷及其建筑对北京城市近代化的影响进行了阐述。东交民巷在元、明和清中叶以前是自然地、逐渐地发展变化的，到二十世纪初则发生了突变。这种突变是由十九世纪末二十世纪初中国内忧外患的政治形势决定的。作为政治事件与不平等条约的产物，东交民巷使馆区建筑群是在短时间内大规模建造起来的。它是美国、日本、俄国和欧洲建筑当时的历史横切片，反映了当时各国的建筑类型、风格、技术。清末民初，东交民巷使馆区作为西方先进城市的缩影，成为改造北京城市的参照物。这些对于北京城市近代化的影响主要体现在城市管理、市政建设、建筑类型与风格等方面。东交民巷使馆区带动了周边地区的发展，促成了王府井商业街的形成。近代历史地段是社会和城市在近代发展的见证，又是当代城市社会生活的载体，同时具有历史性和时代性。如何在发挥其当代城市功能的同时，保护其历史文化价值，是研究者面临的问题。本文通过对历史资料的研究与现状的调查，明确了东交民巷空间功能的历史延续性。在对这一地段的保护中提出了“积极保护，在保护中发展，在发展中保护”的原则，并从地段整体保护和建筑单体保护两方面提出了具体的保护建议。

Located on the east of the Tiananmen Square and the center of Beijing, the Dong-Jiao-Min-Xiang(DJMX) modern historical district was formed in the early twentieth century. Buildings in this area primarily functioned as foreign embassies, banks, trading companies, churches, hospitals, etc. The architectural style of these buildings in the district deeply reflected the popular style of European eclecticism in the late nineteenth century. These buildings have become an indispensable part of the early modern Beijing architectural history. The thesis therefore proposes to provide the in-depth description of the construction, architectural category and art style of the buildings in the DJMX embassy district. The context of the thesis also illustrates the influences of the district upon the modernization the city of Beijing in the early twentieth century.Historically, the transformation of the DJMX was a natural, gradual process until the beginning of the twentieth century, when series of political movements took place in China. These political movements, often accompanied by ‘unfair’ treaty with other countries, lead to the emergence of different buildings and architectural styles from countries such as the United States, Russia, Japan as well as the European nations. The buildings mirrored the architectural development of each country. By the end of Qing dynasty and the beginning of the Republic of China (1911), the DJMX district became the example of the city of Beijing in term of architectural style, municipal management, etc. It also helped the development of the surrounding area, for example, the Wang-Fu-Jing business district.Historical district is a perfect reflection of the social and political life of a city’s past. It is the invaluably significant source for modern historians and cultural researchers. With comprehensive research into both historical materials and future planning development of the DJMX district, the author suggests that architectural preservation and socioeconomic development of the district should be accomplished at the same time. In this thesis, the author also provides information, suggestion, and planning required in order to achieve the proposed goal.
