不同地點標籤對自然度感受及偏好影響之研究

Examining the Effects of Place Labels on Perceived Naturalness and Preference

本研究主要目的在於探討影響景觀自然度感受之因素為何，並比較不同地點標籤中自然度感受及偏好之關係是否有所差異。本研究共選取100張於不同公園拍攝之照片作為本研究之刺激物，並請受訪者針對每張照片之植被豐富性、環境自發生長程度、人工元素多寡、環境整體健康程度、自然度感受及偏好給予1到10之評值。分析結果顯示知覺自然度與植被豐富性、環境自發生長程度及環境整體健康程度呈正相關，與人工元素多寡呈負相關。在不同標籤中，受測者於都市公園標籤中之平均知覺自然度評值高於國家公園組。此外，在國家公園標籤中，偏好與自然度呈現線性的關係，但在都市公園標籤下，景觀偏好與知覺自然度為一倒U字型曲線關係。

The objectives of this study were to explore the factors that affect perceptions of naturalness of landscapes and to examine and compare the relationships between landscape preferences and perceived naturalness in different environmental contexts. One hundred pictures taken at different parks with randomly assigned place labels (national park/urban park) were selected as stimuli for this study. For each picture, respondents were requested to rate their perceptions regarding abundance of vegetation, spontaneous nature, quantity of manmade elements, landscape health, naturalness, and preference on a scale of 1 to 10. Study results indicated that perceived naturalness is positively correlated to the abundance of vegetation, spontaneous nature, and landscape health, while it is negatively correlated with quantity of manmade elements. It is inferred that people will have higher standards with regard to perceived naturalness in a natural environment than in urbanized environments. Regarding the different labels, the same picture was perceived to be more natural when it had an urban park label than when it had a national park label. Additionally, a linear relationship exists between preference and perceived naturalness for the national park group, while an inverted U-shape curve was found between perceived naturalness and landscape preference for the urban park group.
