中文摘要 | 本文嘗試著將臺灣全島之各類林型林木蓄積量估算成碳素購積量,然後求得林 木之CO2吸存存量,同時由生長率的情形來推估未來之每年林木生長量,換算成每年的二氧 化碳吸存,再由每年全臺之二氧化碳排放總量來得知林木生長量之碳吸存佔排放量之百分比 ,以得知林木產生之效益。本研究以1993年林務局第三次臺灣森林資源及土地利用調查資料 ,1993年之林木總蓄積共約3.59億m3,約貯存了4.86億噸CO2,預估到2003年之林木蓄積約 4.92億m3,CO2貯積6.74億噸,1993年之林木年生長量1,082萬m3,預估2003年之年生長量為 1,613萬m3,林木產生CO2年吸存量分別為1,534萬噸及2,282萬噸,此CO2吸存量佔全國年CO2 總排放量之9.86%,顯見林木在CO2的貯積上具正面效益。 |
英文摘要 | This study attempted to evaluate the effects of forest trees on carbon sequestration. Annual growth increment of forest trees was estimated based on annual growth rate. Annual growth stock volume of forest trees was converted into the amount of carbon dioxide sequestration, and which occupied how much percentage of total carbon dioxide emission in Taiwan was appraised. All data used in this study is based on the third survey of forest resources and use in Taiwan conducted by Taiwan Forestry Bureau. In 1993, all forest stock volume was 359 million m3 with 486 million-ton CO2 storage. Forest tree stock volume of 492 million m3 will be predicted by 2003 with 674 million-ton CO2. Annual growth increment was 10.8 million m3 with 15.3 million tons CO2 sequestration in 1993 and the volume will increase to 16.1 million m3 with 22.8 million tons CO2 sequestration by 2003. Annual CO2 sequestration occupied of forest tree 9.86% of total CO2 emission amount, which also meant forest trees had a positive effect on carbon storage. |
