The objective of this study is to investigate the influence of artificial structures and viewing distance on visual evaluation of the natural landscape, the preference of general view of artificial structure, and the factors leading to changes in image of the landscape. A set of visual simulation images were prepared in the form of photo slides by placing seven objects of the artificial structures including buildings and bridges in the natural landscape. The following is the result of a visual-psychological experiment through the photo image of the simulated landscape.
1) The regression analysis in the case of a three-story RC building with flatroof (H: 11.2m, W: 23.5m, ) indicated Y=43.482log (x)-54.387, where Y: naturalness, X: viewing distance, R2: 0.983.
2) The preference of the artificial structure changed its value to the favorite posit-position around 1 degree of visual angle.3) The factor analysis of the image of the landscape indicated that [preperence of the landscape], [complexity of the landscape]v, [size of the artificialstructure] are the primary factors which influence on formation of the image. Also, the entire image of the landscape was categorized into four groups. A case study was conducted in HAKONE Area of FUJI-HAKONE-IZU National Park and the degree of visual influence of the artificial structure in the natural landscape was tested.
