Faced with the health problems of human society brought by the development of urbanization, natural healing (including horticultural therapy, garden therapy, agricultural therapy, forest therapy, etc.) has become an irreplaceable ecological wisdom to promote health. In the research and practice of natural healing, perception is a meaningful and key factor in carrying out natural healing. Although natural healing perception has formed a specific theoretical and empirical basis, the research system is unclear, and the research content needs to be developed. By combining the existing theoretical and empirical research, this paper first explains the concept and connotation of natural healing perception. It clarifies the importance of perception connecting the human (subject) and nature (object). Secondly, from six dimensions (perceptual type, perceptual form, perceptual drive, perceptual dynamic, perceptual duration, and perceptual frequency) and two mechanisms (comprehensive interactivity and comprehensive dynamics), the natural healing perception research content is sorted out in detail. The progress, hot spots, difficulties, and frontier problems of perceptual classification research are discussed. Sixteen subdivided perceptual forms are sorted out based on the five senses. Exploratively put forward the framework of the research system and developed the basic theory of natural healing. Finally, combining with the prospect of natural healing practice, the key research questions of this system are put forward, to provide references for the research and practice in this field from the aspects of perception form, perception mechanism, and perception product.
