摘要

台灣的農地釋出方案將使土地利用產生極大的變化，因此受到衝擊的，如具水利生態環境之農田濕地，都必須思考其未來發展方向來因應。具濕地功能之農田是另一種開發及保護濕地生態為目標的環境資源管理機制，使用現有耕地或廢耕後所形成的具生態條件之人工濕地環境作為野生動植物棲地，在經濟面發展生態旅遊使生態價值成為土地經濟效益之一環，並創造新的地方產業發展契機。為了解濕地環境及其相關保育計畫與措施受到生態旅遊經營影響，有必要探求其造成環境衝擊之可能因子，例如實質環境面（水源、土壤、污染、經營管理等），生物生態面（植物、動物等），及視覺景觀面（物理性、知覺性等）。本研究中採用「德爾菲法」及配合「層級分析法」來評估各因子相對之衝擊權重，以利提供未來執行生態旅遊規劃所必須注意及避免事項之優先順序考量。

The farmland release policy in Taiwan will likely produce a great change in land utilization. In fact, the future development of wetlands still under cultivation in paddies under hydro-ecological environments, as well as land formed in artificial wetland environments after abolishing the plough, must be carefully considered. A farm under wetland style management is an example for utilizing cultivated or abolished farmland to achieve economic benefits for ecological value and increase the farmer's income, e.g. ecotourism. Such usage will create new local industries and develop future opportunities. Nevertheless, to understand the influence on wetlands as well as the relevant restoration plans induced by improper management of ecotourism, it is necessary to seek possible factors in environmental, ecological and landscape scenarios causing various environmental impacts. The goal of this research was to apply the Delphi technique and analytic hierarchy process (AHP) to probe the impact factors induced by the improper design of wetland ecotourism. The relevant weight of the impact factors should be analyzed to offer suggestions for planning and executing future ecotourism projects and avoiding unnecessary interference with nature.
