Cognitive Structures of the Landscape

The nature and structure of Landscape must be studied on the base of our visual actions. The author, in this paper, discussed the distinctions and relations between sensory and spatial views in our visual actions and, as the theoretical foundation for this, the epistemology inherited from Poincare to Piaget was analyzed. Poincare distinguished our visual actions between changes of state and hose of position, and Piaget added the genetic view points to Poincare's Knowledges. 　These studies could give the principles and methods for clearing up the relations between the character and form of materials, and the morphology of spaces, used in the landscape Organization.
