Abstract: The modernization of harmonious coexistence between humanity and nature embodies profound theoretical connotations and ecological philosophy, carrying profound ecological implications. Grounded in intrinsic values such as symbiosis, long-term sustainability, and proactive construction, this modernization clarifies the value proposition of "humans and nature as a life community," pursues sustainable development goals, and advocates creating ecological public values for all humanity. These principles form the core foundation for its ecological value characteristics. It comprehensively considers holistic, comprehensive, and all-encompassing development, establishing dual objectives: achieving the dialectical unity of "ecologized modernization" as progress status and "modernized ecologization" as developmental process. It requires coordinated optimization of ecological civilization with other "four major civilizations," deploys tasks for comprehensive high-quality development embedded with green development concepts, and constructs the ecological framework for harmonious coexistence. To advance this modernization, we must steadfastly uphold the fundamental principles of respecting, adapting to, and protecting nature. We should adhere to an ecological development pattern featuring joint environmental construction, collaborative governance, and shared benefits. By pursuing a civilization path of productive growth, prosperous living, and ecological well-being, we provide clear ecological action guidelines to guide the comprehensive advancement of Chinese-style modernization.
