「都市計畫」也要考量「氣候變遷」因素？國立臺北大學不動產與城鄉環境學系顧嘉安助理教授研究發現，近年來氣候變遷造成的極端氣候現象，屢屢衝擊都市發展，尤其都市地區遭遇嚴重淹水等災害讓建設「韌性城市」、「海綿城市」呼聲四起，也使得「都市計畫」與「氣候變遷」兩領域相互對話合作更具必要性與重要性。

顧嘉安助理教授目前獲科技部補助執行愛因斯坦培植計畫，其研究重點即在於研發因應氣候與環境變遷下進行都市計畫評估之模型工具，如氣候變遷下都市淹水模型、都市土地使用變遷模型、都市風險評估模型等。顧嘉安老師藉由跨領域整合的評估工具，再配合模擬未來都市計畫的建構情境，一方面探索在氣候與環境變遷因素下，未來都市發展的型態是何模樣？淹水風險為何？並據此提出模型工具，實質幫助政府未來進行都市計畫時如何減災、如何降低災害風險以及減緩極端氣候的負面衝擊。

為了使研發模式更實用更具說服力，研究團隊目前鎖定臺北市、新北市、基隆市、桃園市四區域進行模型的模擬建構並評估應用效益，尤其北北基桃四區雖為共同生活圈，但分別面對不同的發展議題，例如交通、經濟、房價、人口遷移等，使得這四區的都市發展型態不同，面對氣候與環境變遷的應變能力也有所差異。因此，研究團隊以此四區作為模型建構，研究初步發現北北基桃之未來空間發展趨勢將會使西半部面臨較大之潛在淹水風險增加，而在不同氣候變遷情境下也需要有不同尺度之因應方式。此外，根據土地利用變遷與淹水潛勢之空間關聯分析結果，得知建成空間、植被及水體之空間型態顯著影響地區淹水深度與範圍，顯示了空間規劃可作為淹水風險減緩之有效工具。未來不僅可對單一區域的都市計畫評估加入減災、防災思維，更可擴及整體區域面，當進行大範圍都市計畫時如何同步將氣候變遷的各項挑戰融入評估，打造永續發展韌性城市。

Facing the Impacts of Climate Change on Urban Planning.

Should we consider climate change in the process of urban planning? According to Assistant Professor Chia-An Ku from the Department of Real Estate and Built Environment at National Taipei University, extreme weather events caused by climate change have had severe impacts on urban development, especially in terms of the negative consequences of flood hazards. This has led to discussions on the concepts of “resilient cities” and “sponge cities” amongst researchers and practitioners, and also the importance of exploring the interactions between urban planning and climate change in related research.

Awarded MOST Young Scholar Fellowship by Ministry of Science and Technology, Chia-An Ku is currently developing a modelling framework that is able to evaluate future urban flood risks considering the spatial and temporal interactions between climate and environmental changes. The framework consists of urban flood modelling, land-use change modelling, and GIS-based risk evaluation. The interdisciplinary methods are applied for understanding the impacts of change in urban environment and human behaviors on future flood risk based on spatial and temporal analysis and simulations, as the foundation for developing effective strategies towards a low-risk urban area under the treats of climate change.

In order to enhance the credibility of the models, Taipei Metropolitan Area, including Taipei, New Taipei, Keelung and Taoyuan Cities, was selected as case study area to calibrate and validate the models. Although connected with each other, each city has its unique developmental issues when facing the impacts of climate and environmental change, and thus need to be addressed individually. Preliminary results found that western part of the region might face the largest increase in flood risk due to urban expansion and climate change in the near future, and this has to be coped with based on strategies at different spatial scales. In addition, it is found that the spatial patterns of built-up, forest, water land uses significantly influence inundation areas and depths, indicating that proper spatial planning can be very useful for mitigating flood risk. The proposed framework can be further extended to wider regions and other disaster-risk-mitigation topics in Taiwan, providing solid reference for sustainable and resilient urban planning in the future.
