환경유사도 분석을 통한 한국 연안역 구멍갈파래 생산량 추정

Abstract

To estimate the total biomass of Ulva pertusa in Korean coastal zone, marine environmental similarity analysis and GIS mapping were performed using Ulva biomass data sampled at some coastal sites, marine environmental data monitored periodically in the whole coastal zone and weather factors consist of atmospheric clearness Index and global solar horizontal irradiation. Additionally habitats locations of Ulva L. consisted of nine species existing Korean coastal zone surveyed in 2007 from National Institute of Biological Resources were considered. According to the environmental similarity rate from referenced some sites sampled Ulva, other unsampled several zone's biomass were estimated. Using GIS the length of coastal line was calculated at each coastal zones divided by 64 regions. And area of each coastal zones was calculated by multiplied length of coastal line by 10m distance from coast to sea. Finally total biomass of Ulva pertusa could be calculated using estimated and monitored biomass data and coastal area at 64 coastal zones.
