摘要

臺灣過去在山坡地的治理工程上，大都以防止災害發生以及注重整體安全為導向，治山防災設施皆設置在低維護管理的環境條件之下，工程後續對於整體視覺景觀的維護上較容易被忽視，大量體人工設施也容易造成負面生心理的感受。故本研究針對高度自然環境中兩種護坡設施，噴漿護坡與自由型框，以照片模擬4種覆蓋比例及4種覆蓋模式，從道路使用者視角進行設施認知(安全、生態、景觀美質)以及景觀偏好調查，並進一步探討個人專業背景及自然連結程度是否會影響其觀點。
研究結果顯示，無論是對於噴漿護坡或是自由型框，綠美化覆蓋比例越高時，受測者的設施認知評值與景觀偏好就會越高。在綠美化覆蓋模式方面，噴漿護坡綠美化位置越接近受測者經過時平視視線時的認知評值和偏好最高，而自由型框則是植草分散種植時獲得最高評價。在個人屬性對於設施認知與景觀偏好影響之結果顯示，專業訓練對於噴漿護坡之安全認知和自由型框之生態認知具顯著交互作用，工程背景對於高比例覆蓋噴漿護坡的安全認知比其他專業背景來的低，美感背景對低比例覆蓋自由型框的生態認知比其他專業背景來的高。而自然連結程度則對各種綠化形式皆不具顯著交互作用。

In the past, the mountain slope management projects in Taiwan mainly focus on the prevention of disasters and overall safety. The mountain disaster prevention facilities are all constructed based on low-maintenance management conditions. The subsequent maintenance usually neglects the visual effects of holistic landscape. The mass artificial facilities also cause negative influences on psychological experiences. Thus, the study was aimed to investigate the people’s perceptions (safety, ecology and aesthetics) and landscape preference on two types of soil and water contractures, shotcrete slope protection and slope grids. Simulated photographs were made in four coverage ratio and four scenic beauty patterns from road users’ vision. Subjects’ profession background and the degree of nature connection were also taken in account while these responses are analyzed.
The results revealed that when slop contractures (both on shotcrete slope protection and slope grids) have higher ratio of green coverage, subjects showed higher evaluations in slop perceptions and landscape preference. In different scenic beauty patterns, shotcrete slope with those beauty patterns closer to the users’ horizontal passing sight, subjects gave higher evaluation in slope perception and landscape preference while the slope grids with scattered grass greening got highest evaluations. In addition, when personal attributes were token in account, the profession background have influences on safety perception of shotcrete slope protection and ecology perception of slope grids. Subjects with engineering profession feel less safe to the shotcrete slope with higher greening coverage than other professions. Subjects with esthetics background valued low coverage slope grids better ecological condition than other professions. Meanwhile, the degree of nature connection had no influence on subjects’ slope perceptions and landscape preference.
