摘要

1996年的賀伯颱風，喚起了社會大眾對森林資源的重視，同年行政院即推行「全民造林運動」，預計五年間共造林50,060 ha。本研究目的在評估全民造林運動已完成之前三年造林（共18,173.76 ha）的二氧化碳吸存潛力，就目前全民造林運動栽植較多的樹種，以生長模式預測未來的生長量，評估未來的二氧化碳吸存量，並以成本效益分析全民造林之經濟性。由結果可以看出，每年新增加的二氧化碳吸存量皆在14.95萬噸以上。以二氧化碳吸存之成本效益來看，當林齡為13年時，造林的投入成本才會低於效益，此時每公噸的二氧化碳吸存成本為NT $ 1,817.75，至20年時，更僅有1,366.65 NT $/ton。

Typhoon Herb seriously damaged Taiwan in 1996, and it aroused peoples' concern for forestry resources. In the meantime, the Executive Yuan has carried out a National Reforestation Program. The National Reforestation Program's goal was completed with 18,173.76 ha of reforestation in the first 3 years. The goal of this research was to analyze the potential for carbon sequestration of the National Reforestation Program. This report chose some species which had already been widely planted to calculate the growth and carbon sequestration, and to perform a cost-benefit analysis. Results indicate that the increase in CO2 sequestration is more than 0.1495×10^6 tons/year. From the view of the economic benefit evaluation of carbon sequestration, costs of planting will be lower than benefits until 13 years later. Costs of carbon sequestration at this moment are NT$1,817.75/ton, and it will be reduced to NT$1,366.65/ton in the 20th year.
