Abstract: The purpose of this paper is to construct a postgraduate mental health promotion model based on the theory of positive psychology and the perspective of mental health promotion. This promotion model is divided into four levels, namely, the demand investigation of postgraduate mental health as the basis, the classified demand as the goal, promotion ways as the core, and the effect evaluation as feedback means. This model is not only concerned about the treatment and development of those postgraduates who are plagued by psychological problems, but also concerned about the development of positive mental characters of normal postgraduates. So it is a set of postgraduate mental health promotion models which is constructed by management, psychology, education and other disciplines concepts.
