摘要

氣候變遷所產生之集中暴雨現象，近年來在世界各地造成嚴重洪患，臺灣為因應此威脅，以都市計畫的方式進行內水防治已形成共識。本研究擬以都市土地使用規劃的思維，將滯洪觀念引入土地使用規劃上，利用劃設特殊土地使用，發揮土地之最大效益，於洪水來襲時吸收洪水的容量，滿足都市安全的需求。本研究以二維漫地流模式進行現況和氣變變遷強降雨之模擬分析，並配合淹水成因探討，訂定空間調適策略，依洪災危害程度劃分調適策略分區，從都市計畫通盤檢討計畫內容之角度，進行調適策略落實於都市空間規畫，其後再針對前述計畫策略結果進行地區整體防減洪效益評估，並以前述結果對減洪規劃手法落實於都市計畫提供具體性參考。

The extreme rainfall phenomenon of global warming and climate change causes serious flooding in many parts of the world. In Taiwan, flooding prevention and mitigation has tried to use the concept of urban planning to cope with this threat. This research uses the perspective of urban planning; therefore, the concept of urban land-use planning must be introduced to the methodology of flooding detention. The application of special land use designation provides detention maintenance and flooding control function by maximizing the effectiveness of land use to absorb flood water and meet the security needs of urban area when the flood occurs. This study proposes that, for build-up areas, strategies should focus on using the fragmented spaces of a city as well as using existing public facility land to increase the retention basin space. To-be-developed areas should be established for flood-volume control, retention basins, rain storage in public facilities, and run-off distribution. These methods should be implemented to facilitate storm water management, improve the disaster prevention ability of a city, and serve as references for city and county governments when engaging in urban planning for flood prevention and control.
