中文摘要細部計畫1:建立海岸濕地本土係數及活動數據研究本研究旨在調查我國海岸濕地（以牡蠣產業為例）的現況面積，並以科學方法估算當地海岸濕地的排放係數。此項研究將有助於揭示本土海岸濕地的碳匯潛力及其在減緩氣候變遷中的作用，並支持永續漁業管理與濕地保護。研究計畫分為三大工作項目：一、調查海岸濕地面積及分析不同海岸濕地的碳匯特性：首先，研究團隊將藉由航測及遙測影像資料分析，確定雲林縣沿岸海岸濕地面積及其分布，特別是包含蚵架的區域。資料來源包括遙測影像、漁業署漁業統計年報及養殖漁業放養查詢平台等，以確保資料的完整性及準確性。其次，為了解不同濕地的碳匯能力，本研究將依循《2006年IPCC國家溫室氣體清單指導原則》及其後續修訂版的指導原則，分析牡蠣產業相關濕地植物體和土壤中的碳儲量變化，並利用碳庫差分法或增減法進行碳儲量的測量和加總。二、建立海岸濕地面積變化監測機制：研究將使用監督式影像分類技術，透過QGIS的Semi-Automatic Classification Plugin工具對遙測影像進行分類和分析。主要步驟包含影像裁切、感興趣區域（ROI）的標註及類別設定，並以已知的地面資料作為光譜特徵的基礎，進行影像辨識和分類。後續將比對漁業署的統計資料，以驗證影像辨識的精確度和結果，進一步了解海岸濕地的變遷情形，並搭配海岸濕地碳匯分析，建立定期的變化監測機制。三、整理分析海岸濕地碳匯本土係數、活動數據及溫室氣體排放量：為估算海岸濕地的排放係數，本研究將針對經TAP驗證的牡蠣養殖區域，以採氣罩技術或邊界層通量法每月監測CO2、CH4和N2O等溫室氣體，以測量濕地的碳儲量及氣體排放通量，透過全球暖化潛勢（GWP）轉換為碳當量單位（CO2e），進行排放係數的計算。最終將根據監測結果，建立海岸濕地本土排放係數及基線資料，為未來相關政策的制定提供科學依據。細部計畫2:建立養殖漁業本土係數及活動數據研究本研究旨在系統性地調查我國養殖漁業的溫室氣體排放情形，並建立具有代表性的本土排放係數、活動數據和基線資料，以提供未來監測和管理的科學依據。本研究將針對虱目魚和文蛤養殖池，優先選擇具水產品產銷履歷（TAP）驗證的養殖場，參考《2006年IPCC國家溫室氣體清單指導原則》等IPCC溫室氣體清單指導原則，測量其碳儲量和溫室氣體通量，確立碳儲量與排放係數，並運用漁業署統計年報和養殖面積數據，進行活動數據分析，以得到我國溫室氣體排放基線資料。最後，本研究將依據IPCC、內政部營建署以及我國藍碳相關碳匯監測標準，提出養殖漁業溫室氣體與碳儲量監測標準作業流程，以確保操作步驟的一致性和數據準確性。此標準流程將進一步作為常規監測的依據，為我國國家溫室氣體排放清冊提供養殖漁業碳排放與碳儲量的完整監測方法、流程與數據支持，有助於推動低碳和永續發展目標。英文摘要1:Establishment of Emission Factor and Activity Data for Coastal WetlandThis study aims to investigate the current area of coastal wetlands in Taiwan, using the oyster industry as a case study, and to estimate the local emission factor for these coastal wetlands through scientific methods. This research will contribute to a clearer understanding of the carbon sequestration potential of local coastal wetlands and their role in mitigating climate change, while also supporting sustainable fisheries management and wetland conservation.The research plan comprises three major tasks:一、Investigation of Coastal Wetland Area and Analysis of Carbon Sequestration Characteristics in Different Wetlands: First, the research team will determine the area and distribution of coastal wetlands along Yunlin County's coastline, with a particular focus on oyster farming regions, using aerial and remote sensing imagery analysis. Data sources include satellite imagery, fisheries statistical yearbooks from the Fisheries Agency, and the Aquaculture Fisheries Release Inquiry Platform, to ensure data completeness and accuracy. Additionally, to understand the carbon sequestration capacity of different wetlands, this study will follow the guidelines of the 2006 IPCC Guidelines for National Greenhouse Gas Inventories and its subsequent revisions to analyze changes in carbon storage within vegetation and soil in wetland areas associated with the oyster industry. The stock-difference method or gain and loss method will be applied for carbon storage measurement and summation.二、Establishment of a Monitoring Mechanism for Changes in Coastal Wetland Area: This study will employ supervised image classification techniques using the Semi-Automatic Classification Plugin in QGIS to classify and analyze remote sensing imagery. Major steps include image clipping, marking regions of interest (ROIs), and defining categories based on known ground data as the basis for spectral feature identification and classification. Subsequently, the Fisheries Agency’s statistical data will be used for comparison to verify the accuracy of the image classification results, facilitating a better understanding of coastal wetland changes over time. Coupled with the carbon sequestration analysis of these wetlands, a regular monitoring mechanism for area changes will be established.三、Compilation and Analysis of Local Carbon Sequestration Factors, Activity Data, and Greenhouse Gas Emissions for Coastal Wetlands: To estimate the emission factor for coastal wetlands, this study will conduct monthly monitoring of greenhouse gases, including CO₂, CH₄, and N₂O, in TAP-verified oyster farming areas, using floating chamber technology or the thin boundary layer flux method to measure wetland carbon storage and gas flux. Emission factors will be calculated by converting these measurements to carbon equivalent units (CO₂e) based on their global warming potential (GWP). Finally, based on the monitoring results, local emission factors and baseline data for coastal wetlands will be established, providing a scientific basis for future policy development. 2:Establishment of Emission Factor and Activity Data for AquacultureThis study aims to systematically investigate greenhouse gas (GHG) emissions in Taiwan's aquaculture industry and to establish representative local emission factors, activity data, and baseline data. This research will focus on milkfish and clam farming ponds, prioritizing aquaculture sites verified by the Traceable Agricultural Products (TAP) certification. Referencing IPCC guidelines, including the 2006 IPCC Guidelines for National Greenhouse Gas Inventories, this study will measure carbon storage and GHG flux to establish carbon storage and emission factors. Additionally, the project will utilize Fisheries statistic yearbooks and aquaculture area data provided by the Fisheries Agency to analyze activity data, thereby creating baseline data for Taiwan National Greenhouse Gas Inventory.Finally, based on the IPCC guidelines, standards from Taiwan’s Ministry of the Interior Construction and Planning Agency, and national blue carbon monitoring standards, this study will propose a standard operating procedure for monitoring GHG emissions and carbon storage in aquaculture. This procedure aims to ensure consistent operations and data accuracy. It will serve as a foundation for regular monitoring and support Taiwan National Greenhouse Gas Inventory by providing a comprehensive method, procedure, and data for GHG emissions and carbon storage in aquaculture, contributing to low-carbon and sustainable development goals.
