氣候變遷導致的極端降雨及海平面上升，極可能對人類生命安全及財產帶來洪水威脅，諸多城市也因此紛紛提出韌性城市概念因應，探究如何面對氣候變遷衝擊仍能維持城市機能。本研究以台北市社子島開發案為例，從地理設計觀點，檢視現行都市規劃成果是否充分納入氣候變遷影響因子，地理設計之主要概念是結合地理及設計兩個領域之專業知識，整合之目的在於輔助規劃設計時能考量環境上的影響因素，並做正確及有效地評估及設計，本研究提出基於水患韌性城市設計之地理設計架構，包含資料分析、規劃設計及支援決策流程，基於韌性城市規劃設計之基礎下，考量氣候變遷對城市所造成之影響進行水患風險分析，並依據分析結果得到韌性城市設計參數；本研究結合半結構式訪談法，彙整當地民眾針對建設、交通及生態三大面向之意見，可促進利害關係人參與規劃設計及決策制定，並能有效納入民眾參與意見，綜整後作為韌性城市規劃設計之基礎資料；最後依據地理設計架構建立地理設計決策支援平台，結合災害潛勢資訊，模擬洪水威脅規模，提出韌性城市規劃藍圖，形成整合科學資訊與民眾意見的氣候韌性都市規劃決策原型。
Extreme rainfall and sea-level rise due to climate change are extremely likely to pose a threat to human lives and properties as flooding. Many cities have proposed the concept of resilient cities, which maintain urban functions in the face of climate change. This study focused on the development plan of Shezidao in Taipei City. From the Geodesign perspective, this study evaluated whether the current urban planning strategy had fully incorporated the influential factors of climate change. The main concept of Geodesign is to integrate the fields of geography and design. Such integration facilitates urban planning by taking environmental influences into consideration for correct and effective assessment and design. This study proposed a Geodesign structure of a resilient city against floods. It included data analysis (GIS-based), design optimization (rule-based) and decision support (web-based) process. Flooding threat analysis was conducted based on the foundation of resilient city planning, whilst taking the impact of climate change to the city into consideration. Accordingly, the design parameters were established from the results. This study also utilized semi-structured interview method to collect the opinions of the local people on infrastructure, traffic and eco-environment, encouraging stakeholders to be involved in planning and decision making, as well as allowing the integration of local opinions. The information was then incorporated into the fundamental information of the resilient urban planning design. Lastly, a Geodesign decision support platform was established based on Geodesign structure. Combined with disaster potential data and flooding threat severity simulation, a resilient urban plan was proposed as a result from a climate resilient urban planning decision model that integrates scientific information and local opinions.
