中文摘要 通過對名間鄉（台灣中部主要產茶區之一）的茶農進行問卷調查，比較了傳統耕作方法（CFM）和有機耕作方法（OFM）的茶園生態系服務價值。首先，調查了包含和不包含抗議反應的樣本的支付意願（WTP）差異，然後進行回歸分析來估算維護茶園生態的支付意願價格。實證結果表明，使用CFM的茶園農民的支付意願與教育程度呈顯著負相關，而同時使用CFM和OFM的茶園則呈現顯著的正相關。大多數受訪者是男性，並使用 CFM 經營茶園；月收入較高且同時使用 CFM 和 OFM 的人願意支付更多費用。對於茶園的生態系統服務，受訪者更傾向於「提供」生態系統服務，並願意平均每年支付718.92新台幣和794.32新台幣用於利用CFM和OFM維護茶園生態。從過去的研究來看，茶園的單位生態價值並不遜於針闊葉林、水田、藻礁等。
英文摘要 A questionnaire survey was conducted on tea farmers in Mingjian Township (which is one of the major tea-producing LEM areas in Mid-Taiwan); and ecosystem service values of tea plantations between conventional farming methods (CFMs) and organic farming methods (OFMs) were compared. Firstly, the differences in willingness to pay (WTP) for the samples including and excluding protest responses were investigated, and then a regression analysis to estimate the WTP price for maintaining the tea plantation ecology was conducted. Empirical results showed a significantly negative correlation between the WTP price and the education level of farmers in tea plantations using CFMs, but a significantly positive correlation in tea plantations using both CFMs and OFMs. Most respondents were male and used CFMs to operate tea plantations; and those with higher monthly income and using both CFMs and OFMs were willing to pay more. Regarding ecosystem services of tea plantations, the respondents preferred the “provisioning” ecosystem services, and were willing to pay an average of NT$ 718.92 and NT$ 794.32 per year for maintaining the ecology of tea plantations using CFMs and OFMs, respectively. The unit ecological value of tea plantations was not inferior to those of coniferous and broad-leaved forests, paddy fields, and algae reefs from previous studies.
