在跨政府氣候變遷小組（IPCC）的引導下，全球各領域的研究者開始由減緩（mitigation）與調適（adaptation）的觀點回應氣候變遷；其中，減緩主要由CO2 排放（emission）與吸存（sequestration）的觀點進行。然而，對於CO2 排放與吸存的研究仍缺乏空間觀點較有系統性的完整架構。此外，將能值分析與模擬（emergy synthesis and siumlation）方法與空間系統模擬結合，將有助於探討CO2 排放與吸存、地景變遷以及能值指標在空間型態上之關連性。然而，對於氣候變遷減緩的努力與研究成果，必需回歸到制度（institution）與治理（governance）上才能有效。因此，本計畫第一年 主要提出CO2 排放與吸存架構，並建構新台中市生態經濟系統，且據以進行能值模擬（emergy simulation）分析，從巨觀的角度探討新台中市能值指標、CO2 排放與吸存、地景變遷與資源消耗之關連性。第二年則建構新台中市空間能值模型，探討能值指標、CO2 淨排放（吸存）、地景變遷與資源消耗在空間型態上之變化。此外，與「政策與空間模型整合彈性機制」結合，以比較各種政策對於CO2 排放與吸存以及能值指標在空間型態上之差異性，作為未來研擬新台中市發展與氣候變遷減緩政策之參考。
Intergovernmental Panel on Climate Change (IPCC) drives researches on mitigation, based on CO2 emission and sequestration, and adaptation for global climate change. However, there is no appropriate system framework from the viewpoint of space to explore CO2 emission and sequestration so far. Combination of emergy synthesis and spatial system simulation can help to analyze landscape change, CO2 emission and sequestration and resource consumption spatially. Researches on climate change mitigation should be connected with institution and governance successfully. Therefore, this research will propose a structure of CO2 emission and sequestration and develop ecological economic system for New Taichung City in the 1st year. Furthermore, emergy indicators and CO2 emission and sequestration are going to be investigated. In the 2nd year, spatial emergy model will be developed to explore mitigation policies of climate change and spatial patterns of landscape change, CO2 emission and sequestration, emergy indicators and resource consumption. The simulation results will be a base to bring up development and mitigation policies for New Taichung city.
