Geomorphologic Characteristics of Seagrass Habitat Distribution in Jin-do Using Remote Sensing Data and GIS

In June 2020, remote sensing survey using drones was conducted to identify the spatial distribution characteristics of Seagrass habitats distributed in Jindo, Jeollanam-do. The Jindo sea area was divided into a land area and a island area according to its geographical location, and the Seagrass distribution area of 1.19744 km2 and 1.35002 km2 was identified, respectively. In order to understand the topographical distribution characteristics of Seagrass habitat, the bathymetric data and slope were analyzed using grid depth data, and the slope was mostly gentle, with a depth of about - 0.5 to - 7.6 m in the land area and - 0.5 to - 13.3 m in the island area. In addition, after analyzing 108 land aqua farms, rivers and lakes, and surface sediment types located in Jindo to determine the relationship between the Seagrass habitat and the surrounding environment, most of the Seagrass habitat was connected to major land water systems. Meanwhile, there were no or few land aqua farms in all areas of Jindo except Gogun-myeon, and the area of Seagrass habitat was 2.54312 km2, which is 99.83% of the total distribution area of Seagrass habitat in Jindo. These research results will be useful data for selecting Seagrass transplant sites for future coastal development projects.
