【 摘 要 】

Biomass is a renewable energy source that is produced from living or recently living biological material. Vegetation type and biomass are considered important components that affect biosphere-atmosphere interactions. The ground assessment of biomass, however, has been found to be insufficient due to the limited spatial extent of surveys. This study aims to integrate field measurements with satellite remote sensing data for regional biomass mapping in Fujiyoshida City, Japan. Fujiyoshida City is situated on the northern slope of Mt. Fuji and includes a large area of forest land, named "Onshirin Forest". From 2011 to 2012, a field survey was conducted to calculate the biomass potential in situ as ground-truthed data. After fieldwork, ortho-rectified ALOS data with an AVNIR-2 scene (22 May 2008) was used to map the vegetation cover types. Japanese larch, Japanese red pine, mixed forest, other forest, grass, bare soil and roads, and buildings were identified using supervised classification. The total plant biomass was 163,252 tons. The biomass potential estimate from field measurements was extrapolated to the large forest area in Fujiyoshida City to estimate the potential plant biomass of specific vegetation cover types.
