空間概念最早提出的是中國的老子「有之為利,無之為用」的觀念。空間所呈現的不僅是外與內,還有又外又內的二元現象之空間。為瞭解這種空間型態存在於建築空間的情形,本研究借以近年來熱門探討的模糊理論,詮釋國道清水服務區的中介空間,並輔以問卷調查方法來探討使用者對空間的感受與偏好之情形,建立評估空間型態特質之模式。本論文以國道清水服務區為實證對象,將其空間經由隸屬函數的定義與計算,區分為戶外、半戶外、中介、半室內、室內5種空間型態,用以調查使用者對空間的偏好與感受,經實證研究發現服務區的每空間多少都有中介化現象,這可能是服務區是一個人造環境有關。而空間型態和空間組合的喜好與空間感受經問卷調查分析後,在喜好上,中介空間型態皆並未有顯著偏好的情形。而在空間感受上,空間型態6項空間因子中,以空間圍蔽(開放/封閉)最為明顯,空間材質(自然/人工)較其他因子偏向不明顯。另空間組合方面則以空間尺度、空間材質、空間圍蔽三項較為明顯,又以空間尺度感受最強,感受最弱的是空間顏色。這些空間因子感受的特性與順序,及空間型態特質評估分析方式,可供未來後續研究探討的參考,且亦可為建築師在對公共建築規劃設計時較具體、清楚遵循的參考方向。
The concept of space was first proposed by Laozi in his Tao Te Ching: “Benefit from what is here, make use of what is not.” Space not only entails outside and inside expanses but also involves a binary space, which is simultaneously external and internal. To understand how this spatial pattern exists in architectural space, this study used fuzzy theory, a popularly discussed concept in recent years, to interpret the in-between space of the Chin Shuei service area along the Taiwan National Freeway. A questionnaire survey of users using the service area was conducted to investigate their perceptions and preferences regarding the space. The results were then employed to establish a model for evaluating the characteristics of spatial patterns. The National Freeway’s Chin Shuei service area was targeted in this study. Its space was divided into five zones, namely outdoors, semi-outdoors, in-between space, semi-indoors, and indoors, according to the member functions defined and calculated for the space. Subsequently, users’ preferences and perceptions regarding spatial patterns and spatial combinations were surveyed. The results of this study showed that all of the spaces in the service area exhibited an in-between phenomenon to some extent, which may be attributed to the entire service area being an artificial environment. According to a questionnaire survey analysis of user preference for spatial patterns and spatial combination as well as user perception of space, the users did not exhibit a significant preference for the in-between space. Regarding the perception of space, among the six factors of spatial patterns, spatial enclosure (open/closed) and material (natural/artificial) were respectively most and least obviously perceived by the users. Concerning spatial combination, spatial scale, material, and enclosure were all strongly perceived by the users. Particularly, users had the strongest perception of spatial scale but they perceived spatial color the most weakly. The characteristics of the spatial factors and the sequence of their perception, as well as the method used to evaluate and analyze the characteristics of the spatial patterns, can provide a basis for future studies. Furthermore, the results can serve as a concrete reference that architects can apply when planning and designing public buildings.
