摘要

Under Article 3.3 in the Kyoto Protocol, it is necessary to monitor aforestation, reforestation and deforestation (ARD) activities between 1990 and the period of 2008-2012 to account net carbon storage by forest. In this study, we developed detectingARD method by subtraction operation using two LANDSAT Thematic Mapper images in Higashi-Shirakawa village, Gifu prefecture. The processing flow of geometric correction, topographic correction, adjusting level of digital number and change detection was established. The consideration of selecting most effective bands for change detection and screening over detection was performed. The results were evaluated accuracy by truth data which was manipulated digital ortho-photo images and IKONOS satellite images. This method can distinguish land-cover type changes and decide a threshold value automatically and objectively, the point is exactly an advantage, therefore this method can become useful method when ARD is monitored for the whole country in the future.
