陂塘為台灣桃園臺地特有景觀及人工構築之地景,由於都市發展與經濟環境演變,水利設施興闢造成陂塘經濟功能限縮,使得陂塘地景急遽變遷與轉型,生態環境亦隨之受到衝擊與破壞,面臨著快速消失的危機。而近年來在地球持續暖化、氣候變遷加劇,卻使陂塘及圳路環境生態功能扮演環境調和的角色。陂塘如何再利用與經濟及城市永續發展息息相關,甚至環境保育、灌溉技術等日益密切及重要,成為必須面對的重要課題。
過去,極少以陂塘的城市功能重塑為核心,進行陂塘發展策略與評估準則的探討。本研究提出一個陂塘發展策略的評估模型,提供政府相關單位與管理者,在進行陂塘各項管理策略與評估指標的優先制定機制;研究係以兩個以上不同研究方法針對陂塘再利用過程分析探討,先採用模糊德爾菲方法(Fuzzy Delphi Method,FDM)研擬評估因子,續以其評估因子利用分析網路程序法(Analytic Network Process,ANP)決策模式工具,求取各待決方案的優先順序權值,建立評估決策模式,藉此選出最佳陂塘再利用與永續發展發展方向與模式,為本研究之特點。
為印證本研究最終結果之績效,再以折衷排序法(塞爾維亞語VlseKriterijumska Optimizacija I Kompromisno Resenje,VIKOR)與重要性及表現分析法(Importance-Performance Analysis,IPA)進行方案現況滿意度之評估,並提出未來改善建議。
研究結果發現陂塘再利用模式中,透過限制開發維持陂塘自然環境之完整性為最重要及需要保持之方案,且可知開發權移轉為最優先需改善之方案,提供改善配套後,最具政府政策發展濳力。其驗證將可作為桃園陂塘整體發展關鍵評估準則與方案。
As a specific manmade landscape, farm ponds were mainly used for agricultural irrigation. Due to the urban development and economic environment change, the function of farm ponds has decreased while the construction of the water conservancy facilities increased. It also resulted in the crisis of the farm ponds vanishing. In recent years, as the global warming and climate change become more intensive, farm ponds accidentally play the important role for palliation. Therefore, the issue to revitalize the farm ponds and make the environment more sustainable, while keeping promoting the economic growth and developing the technology of irrigation has got critical.
In the past, there was very little discussion on development strategies at evaluation guidelines of reshaping city function centering on farm ponds. In this research, Fussy Delphi method was applied to propose evaluation indicators of farm ponds conservation and regeneration projects. Afterwards, the study applied Analytic Network Process method through group discussion to obtain the priority value of each project. Accordingly, we found the optimal pattern of the farm ponds revitalization and the way for sustainable development. Finally, we assessed the satisfaction of the revitalization projects by VIKOR. Further more, Importance-Performance Analysis was applied to evaluate the satisfaction of current regeneration projects.
The result shows that the most important pattern of revitalization is limiting the exploitation to maintain the natural environment integrity of the farm ponds and the pattern should be carried on. Secondly, the top priority of the pattern to be improved is the TDR, which has the potential to be developed after improvement measures provided. This research is expected to be a reference for local government to evaluate the development projects of the farm ponds and set up the revitalization policies in the future.
