| 中文摘要 | 漁港型農地的生物多樣性非常具有價值，提供鳥類棲地與食物來源。然而，環境變遷也正在影響農業用地中的棲地可使用性，因此，在生態系中減輕具有提供鳥類棲地潛力的環境之農地環境壓力，正日漸受到重視。在目前的研究中，我們提出以經驗數據作為基礎，發展農地鳥類棲地永續價值評估的專業方法。起初由專家們齊聚一堂建立研究模型，接著表達他們對環境因素的評論，最後獲得重要的因素如農地破碎度、農業地景異質性等都是影響模型的要素。結合優先權重考量下的優先順序與經驗實驗數據，最終得到結論有31.92%的農地為高度適合鳥類棲息。在牽涉到記錄鳥類分布區域的評估中，從模型中獲得的有效正確率是91.25%。這些結果可以提供當局及政策決策者有潛力的環境系統保育熱點資料作為擬訂政策之參考。 |
| 英文摘要 | Farmland harbors valuable biodiversity, providing habitats and associated resources for birds. However, environmental change is affecting the habitat availability within agricultural landscapes. Thus, conserving farmland areas that have the potential to provide habitats for birds is increasingly considered to mitigate pressure on ecological systems. Incorporating these concerns into bird habitat analysis to aid in conservation actions is needed to assist policy developers in protecting bird habitats in Taiwan efficiently. In the present study, we propose combining an expert-based approach with empirical data to develop an evaluation of bird habitat suitability on farmlands. Experts were initially gathered to construct a research framework and then express their judgments on ecological factors. We obtained the significant factors such as farmland fragmentation, farmland landscape heterogeneity, and distance to surrounding vegetation within fifteen evaluated sub-criteria under four criteria of farmland functionality, farmland utilization, farmland located within a major conservation area, and farmland landscape ecology as the habitat requirements of birds. Combing the weight-based priority and empirical data, we finally determined a highly suitable habitat for birds accounting for 31.92% of farmlands. In an assessment involving bird distribution records in the study area, the accuracy derived from model validation is 91.25%. The findings of this work can provide authorities and policymakers with potential hotspots for ecosystem conservation. |
