| Summary: | 碩士 === 中原大學 === 建築研究所 === 103 === This study mainly discusses whether different plant types and green looking ratio affects the subject's psychological perception. The study method is that compares different plant types and green looking ratio percents by computer simulation. In the experiment one, plant types including grassland, shrub, vertical greening, large trees, small trees, and the percentage of green looking ratio (visual percepted greening ratio) are 6%,21%,36%, and an additional 20% ,35% ,50% green looking ratio in the experiment two.This study discusses the five total plant types with six kinds of green looking ratio configuration of the 21kinds of conditions combinations. And let the subjects evaluate the questionnaires subjectively through watching the 21 sets of pictures from the computer screen. This test adopts subjective evaluation questionnaire of Method of Semantic Differential that is always used on environmental psychology, and the questionnaire evaluation scale is from 1 to 9 levels. The study uses plant types and green looking ratio as the two explanatory variables. The research also uses computer images to explore Psychological greening for subjects. Additionally, the research uses repeated measure method to conduct the research operation.
The results show：(1) The green of plant types such as grassland, shrubs, vertical greening is worse than the green of three-dimensional such as large and small trees. In the plant types, large trees have the best overall performance, followed by small trees and vertical greening, underperformers for shrubs and grassland.(2)The higher green looking ratio, psychological perception, psychological greening and visual preference all get better performance. From this, in urban and architectural environment, to plant planting can improve the visual landscape quality, and increase the user's favor. (3)When the ground is as grass, at a lower greening environment, even if it increases a little of greening, there will be greatly improved on greening effect. (4)Green coverage doesn’t represent the higher feelings of green, In shows again the planting of green coverage and green looking ratio allow users’ feeling to be different.
