在全球氣候變遷的影響下,人類正面臨著因環境變異伴隨而來的各種災害與衝擊,而都市地區因都市化發展與人口高度聚集,一旦遭受極端氣候衝擊,影響更為嚴重,是氣候變遷與環境危害的高風險地區。近年來,氣候變遷議題受到重視,空間規劃領域開始提出透過生態回復力概念來研究都市受到氣候變遷的影響與反應。然而,目前相關研究僅提及回復力概念,或建立回復力指標進行評估,缺乏回復力概念中的干擾前後影響分析,而與氣候變遷相關之都市化研究亦大多以脆弱度為主,較少關注都市化與回復力間之變化關係。
因此,本研究以都市化為前提,探討都市化定義、產生之問題及評估指標,亦探討回復力理論及探討各領域之回復力;其次,以臺北市為研究對象,探討不同時期之都市化歷程,同時建置回復力影響因子系統,以分析臺北市都市化過程與回復力之關係;最後,透過地理資訊系統的疊圖分析,探究臺北市在長時間都市化發展下對回復力影響之時空變化。
Under the effect of global climate change, human is facing the impact of disasters due to environmental variation. Because of continuous acceleration of urbanization and higher concentration of population, urban areas are high-risk regions of climate change and environmental hazards. Major catastrophes may occur when urban areas suffer from extreme weathers. Recently, climate change issues have been emphasized in the spatial planning field, studying the impacts and responses of urban areas on climate change from the concept of ecosystem resilience. However, recent research focused on the theory of resilience and developed resilience index analysis frameworks, neglecting before and after analyses of impacts of disturbances. The relative research of urbanization on climate change also rarely investigated the relationships between urbanization and resilience.
Therefore, this study reviews the definitions of urbanization, including its problems and evaluation indices, and the theory of resilience in different fields. Then, the relationships between urbanization and resilience at different periods of time are analyzed by taking Taipei City as the study area. Finally, the changes of the impact factors of resilience under the effects of the development and the long-term urbanization of Taipei City are evaluated spatio-temporally via the geographic information system.
