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 thataffect perceptions of naturalness of landscapes and to examine and comparethe relationships between landscape preferences and perceived naturalness indifferent environmental contexts. One hundred pictures taken at different parkswith randomly assigned place labels (national park/urban park) were selected asstimuli for this study. For each picture, respondents were requested to rate theirperceptions regarding abundance of vegetation, spontaneous nature, quantity ofmanmade elements, landscape health, naturalness, and preference on a scale of 1to 10. Study results indicated that perceived naturalness is positively correlatedto the abundance of vegetation, spontaneous nature, and landscape health, whileit is negatively correlated with quantity of manmade elements. It is inferredthat people will have higher standards with regard to perceived naturalness ina natural environment than in urbanized environments. Regarding the differentlabels, the same picture was perceived to be more natural when it had anurban park label than when it had a national park label. Additionally, a linearrelationship exists between preference and perceived naturalness for the nationalpark group, while an inverted U-shape curve was found between perceivednaturalness and landscape preference for the urban park group.
