Abstract: Ecological and environmental problems can, to a large extent, be attributed to bad human behavior, so it is a problem not only of economy and technology but also of society, human psychology and behavior. Living in the traditional culture which contains rich ecological thoughts, Chinese people had shaped a social psychology of respecting and conforming to the nature, which correspondingly formed the relevant life style and mode of production. Thus they had ever kept a good relation with the nature for a long time. However, during the process of modernization, these naive ecological thoughts weakened a lot and those good behavior almost disappeared. For this reason, the research on human ecological psychology and behavior not only can help us to understand the influential mechanism of traditional social psychology on the ecoenvironment, but also is of great benefit to the formation of a reasonable modern ecological psychology and behavior. This article discusses how social psychology can influence the ecological construction from four aspects: the relation between human being and ecological environment, life style, social responsibility, ecological and environmental psychology. It was emphasized that the research on social psychology, especially ecological and environmental psycholoy cannot be ignored in the construction of ecoenvironment.
