Abstract: The establishment of the ecological community of the Chinese nation involves deepening and advancing Marxist national theory, inheriting and promoting traditional ecological wisdom from Chinese civilization, adhering to and adapting to the integrity of the geographical environment structure, and unifying theoretical logic, historical logic, and realistic logic. To build an ecological community for the Chinese nation, we must uphold the concept that "man and nature are a community of life" and consider "mountains, rivers, forests, farmlands, lakes, grasslands, and deserts as a community of life" as the ecological support and material basis. The goal is to achieve harmonious symbiosis, a virtuous cycle, sustainable development,and common prosperity among various elements of the natural geographical environment, between the Chinese nation and its regional environment, and between the nation and nature. Using the water conservation area of the upper reaches of the Yellow River in Gannan as a case study, this paper conducts an analysis of its regional practical exploration of the community of life between human and nature, aiming to offer valuable insights and inspiration for the establishment of the ecological community of the Chinese nation.
