都市計畫易淹水地區減洪環境改造策略研究－以板橋浮洲地區為例

Abstract

浮洲地區過去屬於淡水河洪水管制平原，長年以來地方的發展建設受制於限建規定，仍舊保持1950年代都市邊緣的樣貌。直到近年來堤防建設完成，淹水現象才逐漸減少，成為新北市政府積極規劃轉型的地區，而且於2011年成為政府合宜住宅政策計畫選定實施的地點之一。惟目前浮洲地區的基礎設施陳年老舊、功能和服務水準不足，待人口進駐之後，如果沒有全盤檢討和改善都市暴雨排水設施系統，淹水災害勢將無法避免。 最新的都市暴雨管理概念，要求在土地開發的同時兼顧逕流的控制，本研究運用入滲、滯流、滯洪的技術，來探討浮洲地區的減洪環境改造策略。藉由土地使用現況、水文狀況以及淹水潛勢等資料的分析，研擬浮洲地區的暴雨管理改善方案，並指出初步的操作策略，最後則針對如何將治水納入土地使用計畫通盤檢討提出建議。

Fuzhou region used to belong to Tamsui River flood plain control zones. Due to the construction limit, Fuzhou region remains 1950s urban landscape. Until the embankment was raised to prevent rivers from overflowing, the flooding was been mitigated. The government has started to plan the regional transformation of Fuzhou region. Fuzhou was selected to be the location of desirable residential in 2011. But the aging infrastructures make it impossible to serve the growing population. Without a comprehensive review of the urban drainage systems, flooding will be unavoidable in the future. This study aims to use the technology of infiltration, retention and detention to explore the environmental reconstruction strategies for flood mitigation in Fuzhou region. Through survey and analysis the land use inventory, hydrographic condition, flood inundation potential maps and other literature, it then develops stormwater management plan and raises the initial strategies for runoff regulation of Fuzhou region. Finally, it makes a suggestion for how to combine stormwater management with the urban land use planning.
