Landscape lighting of Chinese classic architectures can reappearing the historical, cultural connotation and artistic appeal of architectures at night. Most of these scenes are low luminance and weak contrast, and the visual level is in mesopic vision. Taking the Summer Place as an example, considering the characteristics of vision in different luminance levels, this research obtains a series of simulant scenes with low luminance and weak contrast in mesopic vision by using physical quantity relations between the luminance of actual scene and reappearance scene. Utilizing experiment observation, computer simulation, quantification analysis and subjective evaluation, the research relate the quantitative index and the qualitative description and then realize the synthetically consideration of the relationship between the physics and the psychology stimulation in the lighting environment. Through the statistical analysis of experimental result, it suggests the satisfactory scope of the luminance and the luminance ratio. Similarly, the results of this research have significance to energy saving and the development of green lighting.
