隨著全球氣候變遷與降雨型態的改變,台灣因地狹人稠、河川短促且降雨分佈不均等因素,暫列世界第18位缺水國家;然特殊的地理條件也面臨著地震、颱洪、淹水等危機與災害應變能力之考驗。若能將有限的土地賦予多元之功用,勢必可大大降低先天條件的不足與資源的有效再利用。 鑑此,本研究試圖導入生態觀點當中的「基地保水」項目,以台北市12座都市防災公園為實證對象,進一步探討基地保水之相關法令、執行機制,並輔以國內外理論與文獻、實證基地現況調查等佐證資料的分析,擬定都市防災公園基地保水設施設置之評估體系,透過層級分析法之專家問卷求得評估指標之權重,提出現行都市防災公園空間規劃設計與保水設施設置之課題對策與具體操作方式,以供未來相關單位之參考。主要結論為: 1.目前12座都市防災公園之維生系統與供水儲水設施數量偏低,並與公告資訊多處不符,宜重新檢測與評估。 2.宜採分層分級模式建構各地區之防災公園保水設施設置方針,並訂定各層級所需的規劃原則與整備項目。 3.建立完整的公私合作機制,提升民眾重視安全與防災應變觀念,以確保災時民眾自力救災及降低損害程度。
Following with the global climate change, vicissitude and the rainfall state have been changing too. Many islands faced same problems, such as population increase, short rivers, rain distribution unevenly and other factors, Taiwan is on the listed as the world 18th water scarcity country. However, the special geographical qualification to be confronted with an earthquake, typhoon and flood on crises and disaster strain capacity will be a challenge. If we can use existing land to diverse effect, inevitably it will be able to reduce congenital condition insufficiency and the resources effective use again. According to this research, I try to include ecological viewpoint of water retention. Based on 12 disaster prevention parks as verified object in Taipei City, and to probe into related ordinances, implementation mechanism, theories and literature, site survey analyses, draw up installing water retention fasciitis in the disaster prevention parks appraisal system, and use the Analytic Hierarchy Process of expert questionnaire to obtain weight distribution, bring up to site issues, strategies and concrete operations way provide coherent responsibility department units reference. In conclusion, Firstly, the 12 disaster prevention parks support maintaining livelihood system and water facilities amount are low, and different from the official announced information. They should be re-examined and evaluated. Secondly, the mode of layering ratings should be adopted to construct the disaster prevention park of area to protect water facilities, and the planning principles and preparedness categories of various levels should be drawn up to fit in with the project. Finally, it is necessary to establish an integrated public and private cooperation mechanism, promote the public to pay much attention to safety and disaster prevention, while ensure a disaster self-reliant relief and reduces the extent of damage.
