摘要

本研究目的在於探討民眾對蘭陽溪上游集水區經營管理的看法及對當地資源的經濟評價。針對宜蘭縣大同鄉（區內）與大同鄉之外宜蘭縣其他地區（區外）居民進行問卷調查，瞭解當地民眾對蘭陽溪上游集水區經營管理之看法，並以條件評估法分析該區之資源經濟價值。研究結果顯示，區內及區外居民均認為蘭陽溪上游集水區之自然及人文資源深具價值。以單界二元選擇法評估，得知蘭陽溪上游集水區對區內居民而言，每人每年有1,749.34元的經濟價值，對區外居民則有每人每年560.54元的經濟價值；若以開放式問卷方式評估，則蘭陽溪上游集水區對區內居民而言，每人每年有1,016.82元的經濟價值，對區外居民則有每人每年703.20元的經濟價值。區內及區外居民對蘭陽溪上游集水區經營目標意見不一致，區內居民首重集水區內之經濟發展以確保他們的生計，區外居民則強調水土保持工作以保障他們的生命財產安全。本研究建議蘭陽溪上游集水區之經營管理，可以朝生態旅遊與休閒農業的方向發展，以便有效整合區內發展經濟、區外注重水土保持的不同意見。此外，可為社區居民舉行水土保持教育研習，讓他們分擔水土資源及生物資源保育的責任，並具體執行相關工作，如溪流巡守及魚類復育等，並且可以加強原住民文化保存、舉辦文物展覽、設立博物館及維護傳統慶典儀式等，以深化生態旅遊內涵。

The purpose of this paper was to understand public opinions toward the watershed management and to study economic evaluation of resources in the upper Lanyang stream watershed. Through field questionnaire, we investigated the public opinions about the upper Lanyang stream watershed management. We also evaluated the economic values of resources by applying contingent valuation method. We compared these between inside residents (Tatung township, Yi-Lan county) and outside residents (Yi-Lan county, excluding Tatung township). Results showed that the resources in the upper Lanyang stream watershed were valuable for both inside and outside residents. By the single-bounded dichotomous choice questionnaire method, the economic value were NT$ 1,749.34 and NT$ 560.54 for inside and outside residents, respectively; while by open-ended questionnaire method, the economic values were NT$ 1,016.82 and NT$ 703.20 for inside and outside residents, respectively. We also found that the expected objectives of watershed management were very different between inside and outside residents. Inside residents required for economic development to increase their income, while outside residents required for soil and water conservation to ensure the safety of their life and property. We suggested developing eco-tourism and recreational agriculture in the upper Lanyang stream watershed for effectively integrating the divergent demands of both residents. We also suggested that inside residents could involve in watershed management by environmental education firstly, then by sharing responsibility, and finally by implementing public participation in their interested resource protection activities, such as stream and fishery protection. Some efforts, such as reserving aboriginal materials, building museums, and enlarging the aboriginal traditional activities, would be able to enrich contents of eco-tourism.
