在流域治理議題日趨重要的同時，文獻分析指出非營利部門雖展現積極參 與的意圖與行動，但其意見的能見度、被接受度在政府主導的治理網絡中仍有 偏低的現象。對照非營利部門在其他議題領域的成功與發展，本研究旨在探討 非營利部門的參與可以在臺灣流域治理議題中扮演哪些角色與功能，進而發揮 具體貢獻。本研究選定臺中市筏子溪流域治理議題，採用參與觀察法、深度訪 談法、內容分析法及網絡分析法，分析相關理論與研究成果後，收集六份社區 座談、12份深度訪談紀錄文本，以及10份網絡問卷面訪結果，結合質性文本分 析軟體（MAXQDA 10）及網絡分析軟體（UCINET），探討非營利部門適合在 哪些筏子溪流域治理議題中扮演重要角色？政府權責機關為解決相關議題爭 議，應與哪些非營利組織協力共事？研究發現，為改善筏子溪流域治理問題， 應分從「文史保護、生態保護、生態教育、防洪整治、污染改善、景觀規劃、 治理機制」等七項治理網絡著手，且基於網絡分析的「程度中心性」結果，建議政府權責機關應在各類治理網絡中尋求與非營利組織協力合作，才能有效解決研究個案所遭遇的治理問題。
