Abstract
Global warming and sea-level rise are projected to affect seriously on atolls, which are narrow and low-lying islets on coastal reefs. Coastal erosion or decrease of coastal vegetation would be critical problems for atoll islands. Then, we focused on ground level, land cover and vegetation in the coastal zone, and classified land use of the coastal zone on Majuro atoll. Geographical features and land cover of the coastal zone was able to be divided by using ground truth data acquired in filed investigation, GPS-image, satellite image (IKONOS). Finally, it was proposed that the region where protection measures were necessary and the current state were preserving.
