本研究主要探討不同的植栽類型與不同的綠視率是否會影響使用者的心理感知。研究方式是以不同植栽類型及不同綠視率百分比進行電腦模擬。本研究實驗一所探討的植栽類型包括草皮、灌木、垂直綠化、大型喬木、小型喬木等5種，綠視率百分比(視域中之綠化面積比)分別是6%、21%、36%等3種。實驗二再增加20%、35%、50%等三種綠視率。因此，本研究共探討了5種植栽類型搭配6種綠視率配置出21種組合的條件。本研究是以電腦螢幕播放21組電腦模擬圖片方式讓受測者主觀地對問卷作出評價，實驗採用環境心理學常用之語意分析法作為主觀評價之方法，問卷評價尺度為1~9個等級。研究方式以植栽類型與綠視率為研究變項，利用電腦影像模擬探討受測者對各種植栽所產生的心理綠化量。資料分析方法採用重複量測及相關分析法。 研究結果顯示：(一)植栽類型方面平面型（草皮、灌木、垂直綠化）的綠化不如立體型（大小型喬木）的綠化方式。整體上大型喬木有最佳的表現，其次為小型喬木與垂直綠化，表現較差者為灌木及草皮。(二)綠視率越高，心理感知、心理綠化量及視覺偏好皆有越佳的表現，可見在都市與建築環境裡，多種植植栽可提升視覺景觀品質，也會增加使用者的好感。(三)地被為草皮時，在整體綠化量較低的環境，即使增加一點綠化量，綠化效果也會有較大的提升。(四)綠覆率高不代表綠意程度上感受也較高，再次顯示了植栽平面綠覆率與立面綠視率讓使用者感受是有所差異的。

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.
