Abstract: Contributing to Global Ecological Conservation is one of the basic principles advocated by Xi Jinping's Thought on Ecological Civilization, which is the solution and wisdom put forward by China to cope with global ecological problems and promote world ecological governance.Under the guidance of this international initiative, China not only shares with the world such advanced ecological civilization concepts as "human and nature are the community of life", "harmony between humanity and nature" and "earth life community", but also contributes to the construction of a clean and beautiful world through the construction of green "Belt and Road", addressing global climate change, protection of biodiversity and other vivid practices. In the context of once-in-a-century changes taking place in the world, with the improvement of China's comprehensive national strength, while continuing to strengthen international cooperation, we urgently need to build a more mature and complete discourse system of ecological civilization to further enhance China's international discourse power of ecological civilization.
