In this study, we propose the new method to analyze the composition of landscape pictures and indicate the practicality of new method This new method makes it possible to recognize the two-dimensional picture as the three-dimensional space again by projecting the landscape elements on the surface composed the three-dimensional space. In other words, new method can reduce the complicated landscape construction to simple three-dimensional space using landscape components of two-dimensional pictures. Therefore we call the method "Reduce Method". Using Reduce Method, on this paper, we analyze pictures sampled from tourism pamphlets. As the result, we obtain the fact that tourism pamphlets of Oita Prefecture have the six composition types and that the landscape type and the tourist resort type characterize the each composition type. And we make clear that landscape elements characterize the each surface composed the three-dimensional space.
