Abstract: As an important theoretical achievement of contemporary Marxism, Xi Jinping Thought on Ecological Civilization has inherited the scientific, practical and populist nature of Marxism. It links closely the actual liberation and all-round development of mankind with the liberation of nature, thus forming a contemporary Marxist theory of ecological civilization with profound humanistic connotations. With ecology for the people as the value foundation, the national action as the practical support, and the ecological benefit for the people as the goal, Xi Jinping Thought on Ecological Civilization scientifically and systematically interprets the implication of grand humanistic care and profound humanistic dimension in the construction of socialist ecological civilization. In addition, it has shaped the theory of ecological civilization with Chinese style by thoroughly surpassing the traditional western "anthropocentrism" and "ecocentrism", and contributed Chinese wisdom and Chinese strength to global ecological governance and ecological civilization construction.
