惠蓀林場景觀恢復效益之研究——知覺感知尺度法之應用

A Study on the Benefits of Restorative Forest Landscapes in the Huisun Forest Area–Applying the Perceived Sensory Dimensions (PSD) Approach

本研究邀請自願者在惠蓀林場進行森林療癒體驗並進行訪談，最後以解釋性現象分析來對訪談結果進行分析，希望能找出最具恢復能力之森林景觀。本研究依據感官尺度在惠蓀林場設置了八個實驗空間，受試者在被充分告知並了解本研究之目的與方法的情境下參與實驗，受試者在每個空間中進行15至20分鐘的森林體驗，並於體驗結束後進行訪談，最後共有9名受試者完成體驗與訪談，在八個空間壓力緩解效果的評分上以寧靜、自然、空間之主題空間得到較高之分數，並以寧靜此主題空間得到最高分，表示空間中若擁有寧靜、自然、空間等感知尺度能帶給受試者良好的壓力緩解體驗；此外，依據解釋性現象分析顯示在所有受試者對於各空間的訪談中以「有無遮蔭」、「自然與人造物」、「鬱閉度」等項目最常被提及，而在這之中以有遮蔭、自然、鬱閉度高等環境特性被認為有良好的壓力緩解之效。

During this study, volunteers were invited to participate in forest healing experiences and interviews in eight different experimental rooms in the Huisun Forest Area through perceived sensory dimensions. The interview results were analyzed using interpretative phenomenological analysis (IPA) with the aim of identifying the most restorative forest landscape. Eight experimental spaces based on IPA were established. Subjects participated in the experiment after being informed of and understanding the purpose of this study. Subjects were given 15 to 20 minutes to experience each space, and then interviews were conducted. Nine subjects completed the experience and interviews. In terms of stress relief from the eight spaces, the top three scoring spaces were those themed‘serene’,‘nature’, and‘space’, with the space themed‘serene’scoring the highest. This indicates that perceptual scales such as‘serene’,‘nature’, and‘space’in a room can provide beneficial stress relief. Further, the IPA analysis revealed that during all interviews of the subjects in each room, the themes“shade or not”,“nature and man-made objects”, and“degree of closeness”were most often mentioned, and among these, the environmental characteristics of shade, nature, and a high degree of closeness were considered to have favorable stress-relieving effects.
