摘要

本研究基於燃料特性及燃料分類原則所發展的地面燃料調查模式，透過臺灣現有的森林調查資料成果，應用於大甲溪事業區臺灣二葉松人工林。首先，依據林分植群的特徵，透過階層群聚分析法，建立燃料林型之分型準則，分辨出四種不同燃料林型。因為地面燃料組成是主要影響林火引燃與擴展之關鍵因子，所以利用地面燃料組成進一步發展出19類燃料型。本研究結果發現，臺灣二葉松林分中，不同林型之冠層燃料量的變動較高，約為180~260 tons/ha，佔總林分燃料量之80~90；而地面燃料量之變動較小，約為25 tons/ha左右，佔總林分燃料量之10~20%。

We established the fuel types and applied on Taiwan red pine plantations through the National forest inventory in Taiwan and the fuel inventory methodology which based on the property of fuel and the fuel classification system. First, the Hierarchical Cluster Analysis technique was adopted to classify forest types. Based on the characteristic of stand phenomenon, four forest types were identified for the development of fuel types. Because the composition of surface fuels were the key factor in the ignition and spread of forest fire in Taiwan, ground inventory was conducted to combine the forest types. A total of 19 fuel types were classified. The variation of fuel loading in crown fuel was higher than the variation of fuel loading in surface fuel. The fuel loading in crown fuel was between 180 and 260 tons/ha taking up 80~90% of total fuel loading. The surface fuel loading was much less with only about 25 tons/ha occuping 10~20% of total fuel loading.
