人類活動影響生態系統服務功能的議題，近年來已成為全球人類社會共同關注的焦點，尤其是人類活動造成「土地利用變化」與「氣候變遷」對生態系统碳吸存的影響，從京都議定書的承諾，可看出人類活動與生態系统碳吸存功能間的關係明顯地更受到重視。因此，本研究擬從「人類活動效應-土地利用變化和氣候變遷」的角度，探討人類活動與生態系统功能 -碳吸存之關係，並以三年的時間，依照「生態系統碳吸存研究」、「土地利用變化對生態系統碳吸存影響」、「氣候變遷對生態系統碳吸存影響」等順序，分年執行並完成(1)運用遙測技術，建立即時、有效、經濟、可行及精確的碳吸存估算方法，提供台灣生態系統碳吸存評估之用； (2)根據所建立的碳吸存遙測估算方法，探討人類活動造成的土地利用變化對台灣生態系統碳吸存的影響效應；(3)應用大氣環流模式(GCMs)模擬未來的氣候變化，並探討其對台灣生態系統碳吸存的影響效應。本研究預期效益除了涉及人類社會與國際間共同關注的議題─人類活動對生態系統碳吸存之影響、以及台灣對京都議定書碳吸存議題之響應外，對於台灣有關碳吸存遙測估算研究、生態系統服務功能與價值研究、及永續發展等都具有學術性與實用性的參考價值。
The issue of human activities on ecosystem functions has been growing concern recently. Particularly, the effect of land use change and climate change on carbon sequestration, which is caused by human activities, is regarded as an important research topic based on the promise of ‘Kyoto Protocol’. This study focuses on investigating the relationship between human activities and ecosystem functions (i.e., carbon sequestration) from the standpoint of land use change and climate change. It is expected to achieve this study in three years according to the sequence of ‘study on carbon sequestration of ecosystem functions’, ‘the effect of land use change on carbon sequestration’, and ‘the effect of climate change on carbon sequestration’. The objectives are (1) applying remote sensing technique to estimate carbon sequestration in a timely, effective, economic, feasible, and accurate approach and extend to the assessment of carbon sequestration for Taiwan ecosystem, (2) analyzing the effect of land use change on carbon sequestration based on the above established approach using remote sensing technique, (3) investigating the effect of climate change on carbon sequestration according to the simulation of future climate change using global circulation models. The expected results from this study are related to (1) the effect of human activities on ecosystem functions, which is regarded as an important issue by human society and international organization, (2) Taiwan’s feedback on carbon sequestration issue for “Kyoto Protocol’, and (3) the value of academic and applied research on the remote sensing estimation of carbon sequestration, ecosystem functions and services, and sustainable development.
