[HTT15-P02] Clarification of relationships between coastal dune vegetation and landforms based on ALS and UAS-SfM photogrammetry for nature conservation and restoration: Tottori Sand Dunes, Southwest Japan
Keywords:Coastal dune vegetation, Landform, Restoration, UAS-SfM, ALS
Here we investigate spatial relationships between landforms and vegetation in the coastal Tottori Sand Dunes, Southwest Japan, using high-resolution ground surface information obtained from airborne laser scanning (ALS) and unmanned aerial system-based structure-from-motion (UAS-SfM) photogrammetry.
Vegetation was classified into several communities, and their distribution was mapped based on orthorectified aerial images by using UAS-SfM. We analyzed the spatial correlation using the Jacobs Index. The results indicate that the distribution of vegetation is influenced by western to northern wind in winter and southern wind in other seasons. We found that coastal dune vegetation usually create sand accumulation areas. We also found that short and low vegetation cover communities tend to occur on gentle dunes, whereas tall and high vegetation cover communities tend to occur on steep dunes.
