新竹縣尖石鄉玉峰村的石磊部落因交通不便，觀光發展受限，仍以生產高山經濟作物為主。而為提高經濟作物產量，部落長期實施慣行農業，使用大量化學肥料、藥劑，長此以往，卻也導致土地健康與人體健康遭受鉅大危害；此外，因該部落位處石門水庫上游集水區，其農業活動亦被指為破壞土地健康、造成水庫淤積的主因。有鑑於此，當地原住民族以「山林守護者」自居，揚棄以往的慣行農業，轉型經營有機農業，期望透過推廣友善環境的農法，降低對人地健康之衝擊，並進一步凝聚社區發展共識，以兼顧部落發展與山林保育的雙重目標。爰此，本文以石磊部落為研究對象，運用農業多功能性的分析框架，以文獻分析、深度訪談、參與觀察等研究方法，探討該部落農業經營轉型為有機農業，其所呈現的多功能性，包含提升糧食品質與安全、保存農村生活與文化、建構社會學習與網絡等社會功能，及提供減緩溫室效應與調節氣候、涵養水源及水土保持、增進土壤地力、維護生物多樣性、促進資源循環再利用等環境功能尚能展現，但農民所得與生計等經濟功能則未有明顯提升；故本研究認為有機農業雖能兼顧山林保育與社會發展的目標，但有機產業發展仍有待政府協助推動。最後並研擬建議，以為我國高山農業發展提供可行、適切的經營模式，並作為政府機關研訂管理對策之參考依據。

Yufeng Village — located in Jianshi Township, Hsinchu County and home to the Quri Community — has never had a fully developed tourism industry, due to its remote location and poor road conditions. Inhabitants in the village have instead relied on cash crops as their main source of income. In order to increase crop yields, people utilized conventional agriculture methods, involving large amounts of chemical fertilizers and pesticides, for many years. These practices eventually took a toll on both the land and the well-being of local residents. Additionally, because the Quri Community is located in the upstream catchment area of the Shihmen Reservoir, residents engaged in agriculture in this area were accused of damaging the land and contributing to reservoir sedimentation. In response, the local farmers decided to become “Keepers of the Forests”, and switched from conventional to organic agriculture. Their hope was to encourage environmentally-friendly farming practices that could safeguard the health and well-being of people and the land on which they reside, as well as unite the community under a common vision that balances tribal development with forest conservation. This study focuses mainly on the Quri Community and its practices, and adopts the concepts of land ethics and multifunctional agriculture as a framework for analysis. This study performs literature analysis, in-depth interviews, and participatory observation in order to explore the feasibility of the community’s aim of conserving the mountain and forestry while maintaining economic development. The community intends to achieve this aim by transform adopting organic agricultural practices, and working towards multifunctionality. Its functionalities include enhancement of food quality and safety, preservation of rural life and culture, construction of social learning and network, mitigation of global warming and climate adaption, water and soil conservation, enhancement of soil fertility, maintenance of biodiversity, and promotion of resource recycling. However, the community has not significantly improved the livelihoods and income of farmers. Therefore, this study suggests that organic agriculture can fulfill environmental conservation and social development goals, and only industrial development machinery has to be improved. Finally, this study aims to generate a feasible business pattern for developing mountain agriculture in Taiwan, and to provide a basis for the government to formulate relevant policies.
