平地造林、碳權交易與土地利用之經濟分析：模糊多目標之應用
Application of fuzzy multiple objective approach on the economic analysis of flat land afforestation, carbon trading, and land utilization.
摘要
隨著國際碳權交易市場概念逐漸獲得共識，利用造林減少二氧化碳排放，已經逐漸納入世界各國減緩溫室氣體效應的規範，並且成為台灣近年來在環境規範規劃的重要政策。有別於以往山地造林政策為主要區域，台灣開始鼓勵平地造林，以補助方式達到土地利用與透過林木碳吸存減少環境政策壓力之多重目標。平地造林期間長達二十年以上，並且涉及政府補助、碳權交易、樹種選擇與利用、以及土地利用等因素分析，對從事造林活動的農民而言，經濟性評估成為一項重要的議題。本研究針對平地造林政策，以長期經濟效益觀點，分析政府造林獎勵金措施、碳權交易、碳吸存、木材收益、樹種選擇以及造林投入成本等影響造林活動因素，建構模糊多目標規劃決策分析模式。利用本研究模式與權衡分析方式，可作為政府在碳權交易、木材收益、獎勵金措施之平地造林政策制訂與林農參與造林活動經濟效能決策之參考。 關鍵字：碳吸存、平地造林、碳權交易、模糊多目標規劃

Given carbon trading market as an international recognition of reduction alternative, afforestation becomes an important issue of environment policy to mitigate global warming effect, and so does in Taiwan. Different from the past afforestation focus in mountain regions, the new afforestation policy encourages flat land regions by using subsidiary incentives. Land utilization and carbon sequestration are two goals that the new policy tends to achieve. An economic analysis is needed for policy making and operation involvers. Regarding that the flat land afforestation decision will last more than two decades, related factors such as subsidiaries, carbon-trading, afforestation tree selection and use, and land utilization must be considered. This study analyzes factors that affect the flat land afforestation policy in terms of subsidiary regulation, carbon-trading, carbon sequestration, timber revenues, afforestation tree selection, and related input costs. A fuzzy multiple goal planning is then developed to formulate the problem. Analytical results presented in this study can help decision makers better understand the systematic analysis and potentials for the cost effectiveness of afforestation policy and cultivation makings in practical applications. Keywords: carbon sequestration, flat land affroestation, carbon trading, fuzzy multiple goal programming.
