Abstract: The modernization of harmonious coexistence between humans and nature is the ecological goal of Chinese modernization, and it is crucial to carry out the ecological discourse narrative of the new era. From the perspective of discourse narrative foundation, the discourse narrative of modernization of harmonious coexistence between humans and nature is based on the Marxist concept of nature as the original context, the traditional Chinese ecological wisdom as the local background, and the 100-year ecological practice of the Communist Party of China (CPC) as the direct source. The modernization of harmonious coexistence between humans and nature has its own unique discourse narrative qualities, and a comprehensive discourse narrative analysis of it can summarize the people's position, the transcendence of the narrative content and the pertinence of the narrative theme. The modernization of harmonious coexistence between humans and nature should enrich the connotation of discourse narrative in the continuity of "source" and "flow", shape the theme of discourse narrative in the exchange of "in" and "out", and innovate the way of discourse narrative in the combination of "keeping" and "changing", so as to enhance the communication power and influence of China's discourse narrative.
