在应对城市衰退的策略中,昂格尔斯(O.M.Ungers)提出的绿色群岛(Green Archipelago)概念将紧缩城市作为一种积极现实而非消极问题。既有研究将昂格尔斯提出的绿色群岛城市概念还原到历史语境中讨论并从当代柏林城市现实的视角进行解读以明晰其重要意义。对历史语境的分析包括理论的形成语境和现实语境。首先分析对理论形成具有重要影响的两个要素:申克尔的设计思想;昂格尔斯在康奈尔大学的执教经历。然后分析该理论与当时主导柏林的建筑理论的差异。基于对绿色群岛概念的形成语境和现实语境的分析,可以梳理出该理论的独特之处。最终,本文从柏林当代城市性和临时性利用的角度对该理论进行解读,并认为这一概念在保证当今城市多样性和身份认同层面仍具有重要意义。
In the strategy to deal with the urban recession, the concept of the Green Archipelago proposed by O. M. Ungers tightens the city as a positive reality rather than a negative one. The existing researches return the concept of Green Island City proposed by Ungles to the context of history and interpret it from the perspective of contemporary Berlin city to clarify its significance. The analysis of historical context includes the formation of context and the context of reality. First of all, it analyzes the two elements that have an important influence on the formation of the theory: the design idea of Sheinkel and the experience of Anglers in teaching at Cornell University. Then it analyzes the difference between this theory and the architectural theory that led Berlin at the time. Based on the analysis of the formation context and the real context of the concept of the Green Islands, we can sort out the uniqueness of the theory. Ultimately, this article interprets the theory from the perspective of contemporary urban and temporary use of Berlin and maintains that this concept remains relevant in ensuring urban diversity and identity today.
