Abstract: Since the 18th National Congress of the Communist Party of China, the CPC Central Committee with Comrade Xi Jinping as the core has attached great importance to the construction of socialist ecological civilization and insisted on taking the construction of ecological civilization as an important part of the overall layout of the “five in one” and the coordinated promotion of the “four comprehensive” strategic layout, and emphasized that we must adhere to the basic national policy of resource conservation and environmental protection, adhere to green development, integrate the construction of ecological civilization into all aspects and the whole process of economic construction, political construction, cultural construction, and social construction, increase the strength of ecological environmental protection and construction, and promote ecological development. Civilization construction has achieved overall advancement in key breakthroughs. Comrade Xi Jinping’s series of important expositions on the construction of socialist ecological civilization are lofty in purpose, rich in connotation, and profound in thought. Since March 2019, in accordance with General Secretary Xi Jinping’s important instructions on learning the thought of socialism with Chinese characteristics in the new era, combined with my own work practice, I have conducted in-depth and systematic study and reflection on the excerpts of Xi Jinping thought on ecological civilization. Firstly, study the original. I have carefully studied, thought carefully, and analyzed every paragraph about the construction of ecological civilization in Xi Jinping’s Exposition on the Construction of Socialist Ecological Civilization and the previous speeches of General Secretary Xi Jinping until the end of June 2022. Secondly, the exposition of each paragraph carefully sorts out and classifies the four questions of why to build an ecological civilization, what kind of ecological civilization to build, how to build an ecological civilization, and who will build an ecological civilization. Thirdly, on the basis of sorting and classification, sort out the same or similar contents such as meanings, ideas, principles, measures, requirements, etc., and form Xi Jinping’s position, viewpoints, methods and a series of important thoughts on the construction of ecological civilization, concepts, principles, requirements. Finally, I will systematically summarize these collated views, forming my understanding and thinking about the logic and system of Xi Jinping’s ecological civilization construction.
