摘要: Department of Oceanography Inha University, Incheon 402-751, Korea국외의 대형 무척추동물과 해조류 군집을 대상으로 해역의 생태학적 상태를 평가하는 모델을 이용하여 인공어초와인접한 자연초의 비교함으로써 우리나라 연안역에 설치된 인공어초의 기능도(FI, Functional Index; 군집구조의 안정성과 생산성의 추정)와 성숙도(MI, Maturity 자연초 생물학적 패러미터와의 비교)를 평가할 수 있는, 복수의 지수(ecological index)로 구성된 시스템을 개발하였다. 이 생태평가 서해안 연안바다목장 5개 지역(백령-대청, 연평, 태안, 서천 그리고 부안)의 자연초와 인공어초 또는 어초시설예정지(자연초)에 적용한결과, 기능도(FI)는 지역별로 평균 31.6%(백령-대청)부터 72.5%(부안), 성숙도(MI)는 53.1%(서천)부터 76.9%(태안)의 범위를 나타내었다. 기능도와 성숙도는 태안에서 가장 양호하였으며, 인접한 인공어초와 간의 FI는유의한 선형 관계를 갖는 것으로 나타났다(r
