Due to regional characteristics, marine ecosystem communities, habitat substrates, and marine environment (physical and chemical) are different for each sea area in Korea. Therefore, it is necessary to maintain and manage the marine ecosystem through the conservation and spread of large-scale marine algal communityes by scientifically analyzing the habitat characteristics, and marine forests community structure and area by sea area. In this study, the current state of marine forests by sea area was analyzed by examing the exact conditions of marine algae, barren ground coverage of marine forests distributed in each sea area in Korea. The goal is to develop programs related to the conservation of marine forests by analyzing major marine algae, biomass, coverage of barren ground, and the number of herbivores, and to prepare a grading calculation plan for the protection and conservation of marine forests. Currently, basic information on marine forests distributed worldwide, increase or decrease of marine forest area, habitat information, marine ecosystem stability, species diversity and ecological information are very insufficient. Therefore, it is necessary to establish a marine forest protection and conservation management plan with the analyzed data by converting the marine ecological information into a database based on scientific seabed topography information. The marine ecosystem community structure was analyzed based on the substrate coverage data constructed with multi-beam for an accurate understanding of the seabed topography, and with this data, the basic data for technology development and manual establishment that can produce the most efficient eco-mapping for each habitat characteristic constituted.
