On a macroscopic scale, landscape resources along streams in the Kiso River basin are segmented typologically by way of experimental psychological methods in order to classify their visual quality for preservative and ameriolative planning of riverscape. Riverscapes observed on each viewpoint can be subdivided according to their compositional appearance. Eight major categories of the confrontal riverscape are identified by means of Quantification Theory, while the upstream and the down-stream riverscapes are categorized into twelve and ten groups respectively. Conspicuous elements effective on preference are discerned empirically.
