人行道外側植栽型式對景觀偏好之影響

The Impact by Sidewalk Plants on Landscape Preference

台灣都市人行道之行道樹多栽植於單一植穴，較少設計成植栽帶、並採複層且多樣化植栽配置。但如此設計較生態、較具阻隔機能而提昇安全，另可減緩根害發生機率，且可增進街道景觀。本研究主要目的乃探討人行道外側之植栽型式對景觀偏好之影響，以電腦模擬圖片進行景觀偏好評估。研究結果發現景觀偏好不受性別所影響，但景觀教育程度則呈顯著差異。人行道植栽帶之行道樹下層配置低矮連續植栽的組合型式較被偏好，以灌木搭配草花之複層植栽、種類多樣化，且草花多具高度觀賞性，所形成之景觀視野亦較開闊；但缺乏複層結構、以及下層植栽較高大之景觀，則不被偏好。本研究結果可做為未來人行道外側植栽帶之植栽型式設計之參考。

The multi-levels and biological diversity planting of the street trees is not only ecological, but provides a safer surrounding for pedestrians and improves the aesthetic of streets as well; however, such planting pattern is not applied widely to most cities in Taiwan. The main purpose of this research is to investigate the impact which may be associated with the sidewalk planting pattern on landscape preference by using the visual simulation of different plant heights, width and combination patterns. The result indicated that gender difference does not directly influence the landscape preference. Educational level, however, sinigificantly influence students' preference. In consequence, this study suggested that multi-level planting on sidewalk is more desirable. The height of shrubs and flowers should be lower. The final results would serve as the reference for sidewalk planting design.
