主流纪录片作为传播优秀历史文化的重要媒介载体，承载着询唤大众文化记忆，增强民族认同的使命。新世纪以来，中央广播电视总台顺应时代发展趋势、迎合大众需求，制作出品了众多题材新颖、立意深远，带有主流文化烙印的文博题材纪录片，极大的激发了受众对传统文化的兴趣。这些热播的文博题材纪录片聚焦中华几千年文明历史与社会文化生活变迁，实现了对中国传统文化资源的挖掘与现代化转换，极大地增强了我国国民的文化自信。虽然文化中国具有包容性和对话性，但是受到外来文化冲击、西方文化扩张以及传统文化断裂等多重因素的影响，中华文化的当代价值转化和认同建构依然面临现实困境，亟需借助优秀的媒介文本唤起大众的文化记忆，提振文化自信。基于此，本研究以中央广播电总台作品为例，对新世纪以来文博题材纪录片的文化认同建构展开了深入研究。

在绪论部分，本文阐释了新世纪以来文博题材纪录片文化认同建构的基本性问题。论述了文博题材纪录片文化认同建构的背景意义，梳理了国内外有关文博题材纪录片及文化认同研究的相关文献。

第一章阐述文博题材纪录片文化认同建构的语境与功能。分别论述了文博题材纪录片的内涵与文化认同的内涵及观念演变，文博题材纪录片文化认同建构的语境，以及文博题材纪录片文化认同建构的功能。在语境层面，顺应文化强国战略的社会语境、满足传统文化媒介化生存的媒介语境、抵御西方文化霸权的文化语境共同作用于文博题材纪录片的文化认同建构。在功能层面，文博题材纪录片具有重构文化记忆，传承优秀文化；增强民族认同，激发国族意识；强化伦理认同，提振文化自信的重要功能。

第二章从符号表征、影像呈现、记忆叙事等层面，论证文博题材纪录片文化认同建构的路径。从符号表征看，作为文化实体的文物符号表征了中华优秀传统文化，传递民族精神的人物符号形塑了民族成员的文化认知，抽象凝缩的文化符号生成了中华民族的文化意象；从影像呈现看，影像画面营造真实空间与意境，解说词与同期声引发了情感共鸣，蒙太奇手法勾连了历史与现实；从记忆叙事方式看，多元主体复述交往记忆、场景再现激活文化记忆、创伤叙事重构历史记忆。

 第三章探寻文博题材纪录片文化认同建构的策略。提出在创新符号表征的视觉机制方面，以科技赋能助力符号的可视化表达，打造IP以增强符号辨识度；在丰富影像表达的演绎方式层面，利用语言与图像的互文叙事营造诗意的文化空间，借助三维动画技术提升受众文化体验；在作品传播的受众心理层面，要精准把握受众情感需求，创新文化共情叙事方式。

As a novel media symbol, mainstream documentaries not only have strong resonance with the memory of Chinese people, but also carry the mission of evoking the memory of mass culture and strengthening national identity. Since the beginning of the new century, the Central Radio and Television Station has conformed to the development trend of the times and catered to the needs of the public, and produced many documentaries on the theme of novelty, profound content, far-reaching intention, and with the imprint of mainstream culture. Although "Cultural China" is inclusive and dialogueal, due to multiple factors such as foreign cultural shock, Western cultural expansion and traditional cultural rupture, the contemporary value and identity of Chinese culture still faces practical difficulties, and it is urgent to use cultural documentaries to replace the public's cultural memory and boost cultural self-confidence. Based on this, this study takes the works of China Central Radio and Television Station as an example to carry out an in-depth study on the construction of cultural identity of documentaries on cultural and museum themes since the new century.

First of all, this paper explains the basic issues of cultural identity construction of cultural and museum documentaries since the new century. The background significance of cultural identity construction in documentaries on the theme of literature and museums, as well as relevant literature on cultural identity construction at home and abroad, are discussed, so as to reflect the broad space for in-depth exploration of this research.

Secondly, it expounds the context and function of cultural identity construction of documentaries on the theme of literature and museums. The connotation and conceptual evolution of cultural identity, the context of cultural identity construction in documentaries on

cultural and museum themes, and the function of cultural identity construction in documentaries on cultural and museum themes were discussed. From the aspects of symbolic representation, image presentation, narrative mode, etc., the path of cultural identity construction of documentary films on cultural and museum themes is demonstrated. From the perspective of symbolic representation, cultural relics symbolizes the excellent traditional Chinese culture, character symbols shape the cultural cognition of ethnic members, and cultural symbols generate the cultural image of the Chinese nation. From the perspective of image presentation, the sound and image pictures convey emotional identification, the narration and the simultaneous sound trigger emotional resonance, and the parallel montage lens connects history and reality; From the perspective of narrative mode, individual narrative activates cultural memory, historical narrative inquires cultural identity, and trauma narrative constructs cultural identity.

Finally, the strategy of cultural identity construction of documentaries on cultural and museum themes is explored: in terms of the visual mechanism of innovative symbol representation, we should pay attention to the visual expression of symbols and create recognizable cultural symbols; At the level of enriching the way of image expression, it is necessary to skillfully set up the "other" discourse to generate the subject identity discourse; At the psychological level of the audience of the dissemination of works, it is necessary to accurately grasp the emotional needs of the audience and innovate cultural empathy narrative methods.
