A Suitability Selection for Marine Afforestation with Physical Environments

Abstract: A suitability analysis for marine afforestation was carried out on physical items based on slop rate, bottom sediment, light intensity, vel ocity, and wave at north Geomoon waters in Korea. The data from each physical item were changed to a GSDM (Gridded Spatial Distribution Map) using Kriging interpolation. A GSDM grid includes information, and each grid was given a SI (suitability index) of 3 grades(SI of first suitability was 100, SI of second suitability was 50, and non- suitability had no SI). According to the analysis results of all overlaid GSDM, first s uitability had 500 SI, and suitability area was 0.25ha. Second and third suitability had 4 00~450 SI, and suitability area was 2.36ha, 1.80ha, respectively. Therefore, t he results suggest that reefs installed for marine afforestation should be anti-slip ty pes against steep slope, and the target species need to include algae with low compensat ion light intensity in second and third suitability.
