Abstract

The main purpose of this study is to provide an objective evaluation standard for the assessment of marine spatial characteristics via Ulsan floating offshore wind power project using HEA.. Various levels of damage occur in the waters (5,017.6) near the floating offshore wind power terminals in Ulsan, including commercial damage, ecological destruction and reduction in quality of life due to seascape damage. Alternative restoration projects for calculating the economic value of damage were selected including artificial reef projects and estimates based on HEA. For basic households with a 4.5% social discount rate and a 100% maturity index over four years, the damage was approximately 457 hundred million won. The HEA in this study resolves the possible irrationality in the evaluation of marine spatial characteristics, since the value is calculated based on objective and clear DATA. Therefore, the study results are intended to facilitate conflict resolution between stakeholders in the future during the implementation of the marine spatial plan.

본 연구의 목적은 울산 부유식 해상풍력발전단지를 대상으로 서식지 등가성 분석법(Habitat Equivalency Analysis : HEA)을 적용한 가치평가를 통해 해당 해양공간 특성평가를 위한 객관적인 평가기준 제시에 있다. 울산 부유식 해상풍력발전단지 설립으로 인해 사용이 금지된 해역(5,017.6ha)에서는 상업적 피해, 생태계 파괴 등 여러 피해가 발생한다. 피해의 경제적 가치 규모 산정을 위한 대체 복원사업을 인공어초사업으로 선정하고 이를 HEA로 추정하였다. 추정 결과, 사회적 할인율 4.5%, 4년째부터 성숙도 100%를 기본 가정으로 한 경우 피해액은 약 457억원으로 나타났다. 본 연구에 사용된 HEA는 객관적이고 명확한 DATA를 기본으로 가치를 산정하기 때문에 해양공간 특성평가 시 발생할 수 있는 불합리성을 해결할 수 있을 것이다. 따라서, 본 연구의 결과는 향후, 해양공간계획의 시행에서 발생 가능한 이해관계자들 간의 갈등 해소에 도움이 될 것이다.
