“家园”是人类艺术史上一个重要的创作母题，伴随着人与世界关系的讨论，生态觉醒的时代正在来临，“家园意识”开始出现在大众视野中，并得到越来越多的重视。在面向后现代的生态语境中，“家园意识”不仅隐含着对人与自然关系的本真性认识，也推动着人自身的返本与回归。

本文关注“家园意识”在自然纪录片中的影像表征与具体建构，聚焦生态文明视域下中国自然纪录片的创作表达，从生态整体的角度认识人与自然、人与自身之间的关系，同时进一步探究“家园意识”的呈现如何重塑人与自然关系、讲好中国生态故事，以期丰富中国纪录片的生态实践创作。

本文的正文部分共分为四个章节，第一章从整体上阐述中国自然纪录片与“家园意识”的关系，并将其放置在生态文明的当代语境中，对自然纪录片“家园意识”的萌生、发展、丰富三个阶段进行梳理。第二章在生态文明视域中对“家园意识”范畴进行观察，自然纪录片已形成从“无家可归”到“在家”状态的历时性转向，同时在个体、社会、国家三个维度已形成家宅、家园、家国的共时性建构。第三章在全球化的视野中对自然纪录片中的“家园意识”进行创作表达分析，首先分析中外自然纪录片在生态题材、生态命运、生态价值等方面的创作共性，再讨论其在影像框架、叙事策略、文化语境等方面的“家园意识”差异性表达，最后在中国自然纪录片的寻找、选择与回归中总结梳理出其关于“家园”的独特书写。第四章探索生态文明视域下中国纪录片“家园意识”的现实建构与超越，探讨中国纪录片“家园意识”在景观、记忆、文明三个维度的路径建构，同时对中国纪录片如何“讲好中国生态故事”的具体创新进行探索与展望。

"Homestead" is an important creative theme in the history of human art. With the discussion of the relationship between humans and the world, the era of ecological awakening is approaching, and "homestead consciousness" is beginning to appear in the public eye and receiving more and more attention. In the ecological context of postmodernism, "homestead consciousness" not only implies a genuine understanding of the relationship between humans and nature, but also promotes the return of humans to their roots and return.

The dissertation intends to focuses on the visual representation and specific construction of "homestead consciousness" in nature documentaries, focusing on the creative expression of Chinese nature documentaries from the perspective of ecological civilization. From the perspective of the overall ecology, it understands the relationship between humans and nature, and between humans and themselves. At the same time, it further explores how the presentation of "homestead consciousness" reshapes the relationship between humans and nature, tells the story of Chinese ecology, and enriches the ecological practice creation of Chinese documentaries.

The main body of the dissertation is divided into four parts.The first chapter elaborates on the relationship between Chinese natural documentaries and "homestead consciousness" as a whole, and places it in the contemporary context of ecological civilization to sort out the three stages of the emergence, development, and enrichment of "homestead consciousness" in natural documentaries. Chapter Two observes the category of "homestead consciousness" from the perspective of ecological civilization. Natural documentaries have formed a diachronic shift from "not at home" to "at home" status, and at the same time, a synchronous construction of homestead, homeland, and nation has been formed in the dimensions of individual,  society, and country. Chapter Three analyzes the creative expression of "homestead consciousness" in natural documentaries from the perspective of globalization. Firstly,  it analyzes the commonalities in ecological themes, survival fate, and ecological values between Chinese and foreign natural documentaries. Then, it discusses the differential expression of "homestead consciousness" in terms of image framework,  narrative strategy, cultural context, etc. Finally, it summarizes and sorts out its unique writing about "homestead" in the "search", "choice", and "return" of Chinese natural documentaries. Chapter Four explores the practical construction and transcendence of the "homestead consciousness" in Chinese documentaries from the perspective of ecological civilization, explores the path construction of the "homestead consciousness" in the three dimensions of landscape, memory, and civilization, and explores and looks forward to the specific innovation of how Chinese documentaries can "tell the story of China's ecology well".
