This study purposes to construct supply and demand potential map of forest bioenergy with a GISbased decision support system. The target areas of this study were a part of the forests in Yongdong region, Gangwondo, South Korea and major forest types were pinus densiflora, pinus koreaiansis, and Oak. Data about forest type, age classes, the number of households, regional silviculture planning was stored in GIS to define the potential areas for supplying potential bioenergy from the forests, and to assess biomass available for a household. The number of detached house (about 40,000) represent 74% of total house. Quantity of total annual energy demand in 4 Cities was about 960,000 Gcal. Theoretical total quantity of forest biomass supply was 40,646 ton from the silviculture planning for 10 years, and average value per ha was 0.53 ton. The available quantity of supply for the forest biomass energy of chip was about 86,000 Gcal, and on average 1.29 Gcal per ha could be supplied. However, the supply rate of forest bioenergy on Cities was about 1%, and differences of energy supply rate based on fuel forms were 0.08%. The supply rate of chipfuel was the highest in GS about 1.26%, and for Yang yang, Gang neung, Sam cheok 0.90%, 0.77% and 0.75% respectively. Also, the supply rate for pellet has showed similar tendency with chip form.
