The major purposes of this study were (1) to compare the effect of different stimuli, in terms of image and vocabulary form, by using conjoint analysis, and (2) to discuss the influences of detailed attributes of greening plants on observers' preference. It was expected that the study would find out the relative importance of different detailed attributes in order to be employed as guidelines for future perpendicular greening in urban street.
The study used a computer simulation technique and a questionnaire survey to obtain data. In the questionnaire, the detailed attributes were presented in different forms, image and vocabulary. Three important detailed attributes were selected in according to the results of literature review and each attribute contained three levels. These attributes included the number of color (level 1: 2 different colors, level 2: 3 different colors, level 3: 4 different colors), the contrast of color (level 1: weak, level 2: middle, level 3: strong), and the proportion of greening coverage (level 1: 10%, level 2: 20%, level 3: 30%). In order to obtain the image stimuli for survey, the study utilized a computer simulation technique to create ten urban street scenes including one original without adding any detailed attribute of planting on it and nine simulated scenes with different combinations of planting's detailed attributes. Through convenient sampling, the study obtained 276 valid samples.
The study used the descriptive statistics, t-test, correlation analysis, and conjoint analysis to explain the results and examine the hypotheses. The results showed that there was no difference of effect between image and vocabulary form. However, in the part of image, the most important attribute was the number of color, followed by the proportion of greening coverage, and the contrast of color. In the part of vocabulary from, the most important attribute was the number of color, followed by the contrast of color, and the proportion of greening coverage. Overall, the most preferred one was the scene, which was simulated by using four different kinds of color, weak color contrast, and 30% of greening coverage.
