摘要

京都議定書的簽訂與生效，除要求各國提出國家碳庫資料外，並要求各國估算出境內因碳吸存與溫室效應氣體排放量之差異所導致碳貯存量之變化。台灣超過58%的國土面積為森林所覆蓋，森林生態系可謂臺灣最大的碳庫。然而由於森林土壤調查資料之不足，目前以十多年前第三次森林資源調查的資料為基礎所推估出來的碳庫存量，其除可能與目前實際的土壤碳庫現況有所出入外，亦無法顧及林型、林齡、施業及土地利用變遷等影響。本文回顧國內土壤碳庫研究之相關文獻，並介紹國際上推估大尺度土壤碳庫的方法。建議當務之急為建立詳細且可靠的土綱地圖，並整合土壤容積密度的調查方法，以確切估算臺灣森林土壤碳庫存量，做為將來評估土地利用改變對碳吸存影響之基線。

Since the Kyoto Protocol has come into force, it calls for not only the baselines of national carbon stocks, but also calls for the changes in carbon stocks estimated by net greenhouse emissions and carbon sequestration. Over 58% of the Taiwan land area is covered with forests, the largest carbon stock might be held in forest ecosystems. However, due to the shortage of soil carbon survey, there is still no comprehensive estimation of forest soil carbon stocks in Taiwan. This review paper collects and synthesizes the available information on the Taiwan forest soil carbon researches and the methodology for the nationwide carbon stock estimation. We conclude that for establishing a Taiwan forest soil carbon stock in order to evaluate the effect of land use change on carbon sequestration, there is an urgent need to prepare a reliable soil map and to develop a forest soil bulk density inventory.
