堤防與河灘地美化型式對視覺景觀偏好之影響

The Effect of Landscaping Embankment and Riverfront on the Visual Preference

本研究主要目的在於探討都市堤防與河灘地美化型式對使用者視覺景觀偏好之影響。應用電腦模擬技術將三種河岸開發型態（低度開發、中度開發、高度開發）四種堤防美化型式（無綠美化、局部綠化、完全綠化、牆面彩繪），以及中、高度開發河岸之四種河灘地綠化型式（草地、灌木、喬木、複式栽植）組合成36張河岸景觀模擬照片，由河濱公園現地使用者針對模擬照片進行景觀偏好之評分，再以重複量數多變量變異數分析、單因子變異數分析以及T檢定等統計方法進行分析。主要之研究結果如下：一、堤防與河灘地之美化型式會影響視覺景觀偏好。二、當控制「河灘地綠化型式」變項時，不同「堤防美化型式」間之差異會影響都市河岸之視覺景觀偏好。三、就個別都市河岸景觀偏好分別比較結果，受訪者「是否受過相關之景觀專業訓練」及「來本公園主要從事之遊憩活動」兩項特性對都市河岸視覺景觀偏好有明顯之影響，而「性別」、「年齡」與「職業」對視覺景觀偏好之影響較小，至於「教育程度」則無影響。

The purpose of this study was to explore the effect of landscaping the urban embankment and the riverfront on the user's visual preference. Computer simulation technique was used to compose thirty-six sets of photographs to simulate the scenes of the riverfront which consisted of three sty les of river front development (less developed, highly developed, and those in between), four types of embankment landscaping (ungreenery, partial greenery, total greenery, and wall painting) and four kinds of greenery (grass , shrub, tree , and multilayered plant) on the medium and highly developed river front . The photographs were rated by the 'field-experiencing' users of the river side park according to their visual preference. The major results are summarize d as follows: 1. The landscaping types of embankment and the riverfront have significant influences on respondent's visual preference. 2. Different landscaping types of embankment have effect on respondent's visual preference while the variable, kinds of greenery on the riverfront, are controlled. 3. Two characteristics, 'professional training in the field of landscape' and 'the main recreational activity engaged in the park' have significant influences on visual preference for urban riverfront. Furthermore, the factors such as sex, age, and occupation seems to have only minor influences on the visual preference. The level of education is no difference in this case.
