• 中文摘要： 本研究提出一個包括7個狀態變數的模式來描述有機質在土壤中轉化的過程，該模式的建立是根據動態系統分析原理，參考文獻上目前已知的各種土壤有機質轉化的機制，取其優點組合而成。土壤水分及溫度對有機質轉化的影響亦藉降雨、氣溫等氣象因子函數關係予以討論與設定。最後以該理論模式模擬了土壤有機質轉化的一些定性上的特性。
• 英文摘要： A model with seven state variables for describing the transformation of organic residue in soils hasbeen proposed. The construction of the model was based on the theories of system dynamics and also onthe mechanisms obtained from literatures for the turnover of soil organic matter. The effect of soil mois-ture stress and soil temperature were discussed in relation to the variations of precipitation and air tem-perature. Two methods were proposed for possible application to fit the data base of the climatic factors.Finally the assembled model was qualitatively tested.
