綠色堡壘：台北新圓環之綠活論述、自然再現與偽公共空間

Green Fortress: Green-life Discourses, Representations of Nature, and Pseudo-public space of New Jiancheng Circle, Taipei

建成圓環改建緣起於市場現代化政策，受台北市都市發展影響，納入新自由主義治理範疇，採綠活導向之ROT模式，重新定位場所機能與再生地方意象。本文分析該模式之歷史意義與市民使用經驗，研究方法為歷史分析、行為地圖調查、半結構訪談，透過政治生態學理論，探討自然在圓環更新案之意義轉變。第一部份探討圓環歷史之自然形式變遷，以2000年初台北車站特定區規劃採用之綠活論述與圓環最初之綠地構想，作為2007年民營化後綠活設計之對照點；第二部分評估市民使用空間之經驗，以定位2012年後自然在新圓環之角色。研究發現圓環從初期綠地構想、綠色消費，至現階段之複合展館，自然元素從實質自然，轉變至社會自然，最終成符號化之第三自然；民眾隨之產生高級化與現代感、神秘感與領域性、排外性與壓迫感三大面向感受。隨圓環之自然層級改變，場所公共性逐漸降低，本文發展出「綠色堡壘」概念界定挪用綠活意象之「偽公共空間」（pseudo-public space）與都市再生策略，雖創造高品味意象，卻缺乏活動包容性與空間友善性，犧牲場所可提供之公共生活，長期終難以真正活絡地區。結論反思自然元素在建築設計中角色，且建議政府、專業者與民眾可改善前述問題之作法。

Beyond a modernized marketplace, Jiangcheng Circle in Taipei has become an object of the citys neoliberal urban governance since the early 2000s. Holding a ROT contract with the Municipality, a company remodels the building into a facility symbolic of green lifestyle by taking major influence from the "nature". This paper examines the historical significance of its green-life oriented redevelopment, while evaluating users experiences. Research methods include historical analysis, behavior mapping and semi-structured interviews. The analyses employ a framework of political ecology to uncover the implications of the redevelopment. The first part reviews the changing forms of nature, contrasting the post-privatization period with the early 2000s when green-life inspired planning discourses first emerged. The second part evaluates users experiences to clarify the roles of nature after 2012. The paper considers the citys original plan of green space as well as the investors green-consumption business as the Second Nature, while identifying the latest uses of landscape design and horticulture as the Third Nature. As the level of nature changes, Jiangcheng Circle becomes an exclusive environment. Users perceive it as a place characterized by such images as "modern and high-end ", "mysterious and territorial", "exclusive and confined". The paper develops the concept of "Green Fortress" to theorize a new type of "pseudo-public space". A "Green Fortress" may temporarily catalyze property development with enhanced images, while failing to revive a neighborhood in the long run. The conclusions rethink the significance of nature embodied in architectural design, suggesting solutions for public officials and design professionals.
