生物质是一种可再生能源，由活的或最近活的生物材料产生。植被类型和生物量被认为是影响生物圈-大气相互作用的重要组成部分。然而，由于调查的空间范围有限，人们发现对生物量的地面评估还不够。本研究的目的是将实地测量与卫星遥感数据相结合，用于日本富士吉田市的区域生物量制图。富士吉田市位于富士山的北方斜坡上。富士山内有一大片林地，名为“Onshirin森林”。从2011年到2012年，进行了实地调查，以计算现场的生物量潜力作为地面真实数据。在实地工作之后，使用经正射校正的ALOS数据和AVNIR-2图像（2008年5月22日）绘制了植被覆盖类型图。日本落叶松，日本赤松，混交林，其他森林，草地，裸露的土壤和道路，和建筑物进行了识别，使用监督分类。植物总生物量为163，252吨。从实地测量的生物量潜力估计外推到大的森林面积在富士吉田市估计潜在的植物生物量的特定植被覆盖类型。
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.
