可利用性的空間政治：臺中車站暨周邊公共空間的場景構作與身體繫留

The Spatial Politics of Affordance: The Scenes-making and Corporeal Mooring in Public Space around the Taichung Station

臺中車站高架化偕同周邊都市更新與綠川整治，深刻改造了舊城紋理。作者關注以臺中車站為核心的公共空間轉型，如何部署新的環境可利用性，卻形成排斥的美學化場景。相對的，邊緣群體持續在身體繫留中挪取環境特質，塑造適應需求的空間功能與地方意義。作者從事實地觀察，並訪談主管機關人員，獲得以下發現：首先，景觀化的公共空間不鼓勵停留、座椅極少，也忽略臺灣氣候特徵。其次，空間設計雖受重視，但貼附於美學化皮層的引導、禁制和宣傳圖文，透露著突兀的管理主義氛圍。第三，人群靈活辨識環境可利用性來安頓身體並漸受寬容，但街友與外籍勞工的蹲佔躺臥，卻承受較嚴格管制。公共空間生產與建構的可利用性政治，彰顯為美學場景化的難以使用，以及不同人群挪取環境可利用性之身體姿態的差別待遇。場景構作與身體繫留的緊張，透露出都市領域化治理、紋理可利用性，以及身體皺褶行動之間的動態。

The elevated construction of Taichung Station, along with the reconstruction of Green Waterway, has profoundly reshaped the textures of the old city centre. We shed light on how the transformation of the public space around Taichung Station has deployed new environmental affordance while producing rejective aestheticized scenes. On the contrary, marginalized groups have been constantly appropriating the environmental features in their corporeal mooring to shape spatial functions and place meanings that suit their own needs. Through on-field observation and in-depth interviews with key officials, we have found that, firstly, the landscaped public space does not encourage one to stay, given that it offers few seats and has failed to take the climate of Taiwan into account. Secondly, even though spatial design seems to gain importance, an abrupt sense of managerialism still reveals itself with the many placards and signs that work to guide, ban or promote certain behaviours posted upon the aestheticized surface. Thirdly, people are increasingly allowed to flexibly recognize their own environmental affordance to settle their own bodies, but the homeless and the foreign workers are still rather strictly regulated to not to squat or lie down. The affordance politics of the production and construction of public space hence embodies itself as the difficult usability of the aestheticized scenes, as well as the differentiated treatment different groups receive in their appropriation of the environment. The tension between scene making and corporeal mooring has testified to the dynamics between territorialized governance, affordance of textures and corporeal foldings.
