探討適於韌性城市之滲透貯水設施創新設計

Discussion on Innovative Design of Permeable Storage Facilities Suitable for Resilience Cities

台灣為亞熱帶氣候國家，雨量非常充沛，但是受到近年極端氣候的影響，經常出現缺水與洪患之危險。因此本研究整合韌性城市建構概念與綠建築基地保水及都市微型水庫塑造等水資源環境理念，探討在都市中有效貯集與儲存龐大雨量的創新設計策略，達到面對極端氣候防患未然之作用。 本研究應用徐昇氏網圖建立彰化秀水測站影響範圍，蒐集雨量資料，計算降雨延時之平均降雨量，進行廻歸分析產生重現期資訊，推估Honer雨型公式與氣象局雨量危險級距做比較，評估當地在兩年重現期間受到最大降雨影響的危險性，並且提出仿生創新規劃設計都市微水庫策略，提供適於韌性城市增加滲透貯水應用之參考。

 

Taiwan features subtropical climate with abundant rainfall. However, due to the extreme weather in recent years, water shortage and flood occur frequently. In order to integrate the construction concept of resilient cities with the rainfall storage, this study suggests building urban micro-reservoirs, and the concept of water resource environment, and explores the design strategies for effective rainfall storage and storage of huge rainfall so as to take preventive measures in case of extreme climate. In this study, the Thiessen’s map is used to establish the range of Xiushui station to collect rainfall data and calculate the average rainfall within duration. Then, the regression analysis is conducted to generate the return period information, and estimate Honer rain type formula and compare the results with rainfall risk level of the meteorological bureau to assess the risk of local maximum rainfall during the two-year recurrence period. The bionic innovative planning and design strategy is also proposed to provide a reference for increasing the application of osmotic water storage in resilient cities.
