Abstract: Eco-centrism regards the interests of the ecological community as the highest value and puts nature into the scope of human moral concern.Although it makes a vivid interpretation of the symbiosis between man and nature,it breaks away from human practice and dispels human subjectivity.Ignoring the demands of human survival and development,it places hopes on individual moral behavior in order to reach the utopia of the wilderness.In contrast,the idea of "life community" is the latest theoretical achievement of applying Marx's practical view of nature to the relationship between man and nature,which integrates the practical experience of socialism with Chinese characteristics in the construction of ecological civilization.Based on production practice,it reveals that man and nature are life communities,confirming man's subjective responsibility,and clarifying "the law of beauty".From the dimension of practice,the idea of "life community" provides a Chinese plan for how to realize the harmonious symbiosis between man and nature:it adheres to the systematic ecological methodology,and is the ecological governance theory of implementing subject responsibility with the co-governance of virtue and law and the ecological value theory from beautiful China to the realization of human sustainable development.

Key words: life community, ecology, nature, human
