摘要


澎湖濕地資源豐富,鳥類調查資料亦詳盡(包括39個地點、219種鳥類的族群數據),以其生態資源為基礎,應用生態學與經濟學的理論方法,研究生態資源利用之規劃,可對其他生態資源提供保育與利用之規劃參考,因此本研究以生態資源永續利用的觀點,結合生態觀點與經濟觀點之技巧進行評估,以便提出澎湖縣鳥類資源永續利用的規劃與建議。本研究包括生態評估及經濟評估兩部分。生態評估又包括指標法和保護網法,經濟評估則將生態評估結果設計於條件評估問卷內,以估計澎湖濕地之價值。本文利用條件評估法的支出函數模型評估澎湖濕地的存在價值,以最大概似法(MLE)估計雙界二分選擇問卷,結果為顯著影響支付意願的變數有訪員感覺受訪者對問題的了解程度(α=1%)、是否願意參加澎湖賞鳥旅遊活動(α=5%)及職業類別(主管、經理及專業人員,α=10%)。這些變數對支付意願的影響皆為正向影響,表示對問卷了解程度較高者、願參加澎湖賞鳥活動(即選擇價值為正)者及職業為主管、經理及專業人員,其對存在價值的支付意願較高。存在價值估計值為1452.50元,其α=5%信賴區間為(1050.73元,2020.23元),亦即澎湖濕地的存在價值介於1050.73元至2020.23元之間。本研究結果可作為安排賞鳥觀光路線之參考,亦可提供保護澎湖濕地之價值依據,可作為未來保育與開發濕地決策時之參考。

The conservation and the utilization of ecological resources do not necessarily stand against each other. Appropriate utilization under proper management may, on the contrary, become an additional approach for ecological resources conservation. This research, in concerns of sustainable utilization, applies the ecological and economic theories to study the ecological resources utilization schemes.We apply the indicative method and the network method of ecological evaluation to construct the bird-watching recreational networks in Penghus and make comparisons. For the values of the bird-watching recreational networks, we apply the dichotomous-choice contingent valuation method of economic valuation, and combine with the randomized response method for asking sensitive questions. Indicative method uses ecological data (including area size, habitat and ornithological diversity, ornithological rarity, population size, and representativeness) of Penghus to construct a mix index for wetlands. Network method is to construct bird-watching recreational network concerning ornithological diversity. The ecological evaluation results were then introduced to the dichotomous-choice contingent valutaiton questionnaire. Camerons's expenditure function model and maximum likelihood estimation provided by Alberini et al. are used to estimate willingness to pay values of bird-watching recreational network in Penghus.The significant variables affecting the willingness to pay (WTP) include the degree of understanding the questions (α=1 %), willingness of attending bird-watching activities in Penghus (α=5%) and occupation (α=10%). The estimated median annual willingness to pay is NT$1452.50. The confidence interval under α=5% is (NT$1050.73, NT$2020.23).This study provides profound reference for future conservation and utilization plans of ecological resources.
