都市貧民窟自來都是都市更新與再發展的重要施行對象，而在都市更新漸次成為臺北市重要的政策議題下，堪稱為臺北市貧民窟代表之一的整建住宅社區，自I980年代初期以來，也不免成為臺北市都市更新推行的重要標的區。但是，如同其他城市的貧民窟一樣，臺北市整建住宅社區的存在，也有其特定的空間與社會發展脈絡，以及其城市特殊性的貧民窟特性，是探討都市更新與再發展所不可不察的。本文以位於臺北市最具規模的國宅社區一青年公園國宅區週邊的南機場一期整建住宅社區作為個案，探討臺北市特定類型貧民窟形成的社會空間歷程。著重於探究臺北市的整建住宅社區具有何種貧民窟特性與意涵，以及整宅社區的發展與變遷和都市與社會動態的關連性。

This paper takes the Nan Chi Chang Community as a case study of the formation of urban slums in Taipei City. Nan Chi Chang Community, as is the case with other resettled tenement communities built between 1962 and 1975 to resettle squatter residents, has been identified by government officers, the media and even the residents themselves as being in urgent need of renewal. Why is it that a resettlement project for squatter clearance seems unable to avoid becoming a slum few decades later? It is argued in this paper that the spatial and social processes of slum creation should be thoroughly understood before any renewal project is initiated. If this is not the case, there is the distinct possibility that the slum will merely continue in the same place or be transferred to another place. The paper focuses on an examination of the often unique characteristics of slum communities in Taipei City and in particular the processes of slum creation that have obtained during the past four decades.
