Description: The objective of this study is classification of fuel type and calculation of fuel loading to assess forest fire hazard by fuel characteristics at Uiseong-gun, Gyeongbuk located in the central interior of Korea. A database was constructed of eight factors such as forest type and topography using ArcGIS 9.1 GIS programs. An on-site survey was conducted for investigating vegetation and fuel loading. Forest distribution of Uiseong-gun is composed of mixed forest, about 43.7%, of coniferous trees such as Pinus densiflora, approximately 43.5%, and of broad-leaved trees like Quercus variabilis, 8.7%. In order of age class, trees are III-class (11~20 years) 57.6%, IV-class (21~30 years) 25.1% and II-class (1~10 years) 14.4%. By diameter at breast height (DBH) 82.5% are small diameter, 6~16 cm, and 14.9% of young trees are under 6 cm diameter. Most trees are are less than 16 cm DBH. Considering Korean forest characteristics this study led to a classification of ten fuel types. With the utilization of the data taken into account, this research, based on the existing forest type and forest soil map, categorized the 10 fire fuel types into three coniferous forests (C), one broadleaf forest (D), and one mixed forest (M), five fuel type forests in total. In shrub layers and below them, fuel load was found to be 7.64 t/ha in Pinus densiflora pure forest (C-1), 10.99 t/ha in the Pinus densiflora-middle stratum (C-2), 8.62 t/ha in the Pinus densiflora-substratum (C-3), 9.17 t/ha in the mixed forest (M), and 1.01 t/ha in the broadleaf forests (D). To categorize fuel types in drawing a forest fire fuel map, the research analyzed the relationship between the density of coniferous forests (C-1, C-2, and C-3), fuel load and forest soil conditions.
