In response to the environmental crisis, the western social work is undergoing a green turn, which has also exerted its influence on the Chinese social work. When accepting the influence of the west, Chinese social work needs to pay attention to the corresponding local ideological resources. Fei Xiaotong's discussion on the Unity of Man and Nature, Recreational Economy and Human Ecology is of great significance for us to promote the green turn of Chinese social work. First, the sociological interpretation of Unity of Man and Nature from the perspective of differential order pattern by Fei Xiaotong, can help us get out of the implicit tension in the green turn of social work. Second, as a local economical attitude and life style, Recreational Economy provides us with local experience to transcend consumerism and explore an alternative community development path. Finally, according to Fei Xiaotong's Human Ecology, development is still an important task facing China, and therefore, to protect the natural environment is not to give up development and the exploitation of natural resources, but to combine natural ecological protection with human ecological construction.
