  • The purpose of this study is to create a planting design for progressive realization. For this, visual preferences as measured via questionnaire were evaluated by the Scenic Beauty Estimation(SBE) and paired comparison methods. The results can be summarized as follows. Through photo observation, the average visual blockage ratio was 38% and the range of degree of the visual blockage ratio was $30{\sim}50%$. The sketch simulation and filtered pattern received the highest preference score and fumed out to be the most practical pattern out of all the patterns evaluated. Also, in the sketch simulation, the high preference values were observed for a distance of 9 to 12m from the view point to the blockage tree with a D/H ratio of 2. The preference score significantly decreased with the increase of the visual blockage ratio having a turning point at $30{\sim}35%$ of the visual blockage ratio, even though the distance parameters were more important than the visual blockage ratio in the scores. An outstanding view must be handled properly to be preserved or accentuated. Framed, open, enclosed, screened or filtered pattern views should be completely revealed only from their best vantage point, not given away at first glimpse. It this sense, parallax spatial beauty with trees could be improved through the visual aspects of plan arrangements and seems to be an effective design technique for landscape planning and planting design.

  • Although the coastal area of Jeju has already been developed, it has high pressure and demands for development continually increasing due to the increase of tourism and leisure activities. Therefore, the purpose of this study is to present objective guidance for the planning of the buildings on the seaside road with a view which have the largest impact on coastal landscape in order to enhance its visual quality. The results of this study are as follows : 1) It is chief element to make guidance for the use and planning of buildings in the conservation of the coastal landscape. 2) The D/H ratios which immediately influence an angle of elevation are different one another for the whole street. To ensure a sense of openness for the landscape, it is needed to maintain under $27^{\circ}$ angle of elevation, which demands 1~3 D/H ratio. 3) It is important to make 2.4 visual blockage ratio for whole street, but the actual condition is 4.48 ratio on average. To bring down the visual blockage ratio, the W/D ratio needs to be regulated. 4) Various techniques are also needed for lively building styles going with coastal landscape.

  • Recently the landscape of housing has been emphasized. This trend seems to reflect the negative aspects of housing landscape in urban area. Throughout the analysis on the various visual density index, the following findings were obtained; 1) Elevation blockage ratio(EBR) was permitted differently according to the types of housing blocks, and the preference of block layout was different to the location of site. 2) EBR regulation level was acceptable. But 40m level of general area should be stepped up to the 35m level. 3) The correlation between the floor area ratio(FAR) and the EBR was not high. Therefore it is reasonable to regulate the EBR to the location. 4) Elevation coverage ratio(ECR) was highly correlated with the FAR. It means that FAR can substitute for the ECR, and ECR should be regulated to the level of FAR.
