摘要：It is expected that the remote sensing techniques will play a major role in establishing the carbon sink assessment system to meet the need of the Kyoto P rotocol. Tree cover percentage is one of the useful parameters in estimating CO 2 absorption. Purpose of this study is to investigate the correlation between tree cover percentage and 15-30 m resolution TERRA/Advanced Spaceborne Thermal Emission and Reflection radiometer (ASTER) optical sensor data. First, airborne laser scanning data – better known as airborne light detection and ranging (LIDAR) sensor data, are obtained in the forest of 1 km 2 in area, Japan. The forest as the study area is classified into five kinds of landform such as 1) crest slope, 2) head hollow, 3) slope facing east, 4) slope facing west and 5) valley. Tree cover percentage in each landform is calculated by the LIDAR data. The tree cover percentage is overlapped on the TERRA/ASTER data, and the relation between them is investigated. As a result, an adequate correlation is estimated between the tree cover percentage and TERRA/ASTER data in the crest slope and the valley. In order to estimate global level tree cover percentage, there is the possibility to adopt this correlation to 1 km resolution SP OT/VEGETATION data. But more investigation will be needed in the future study
