초록

본 연구는 천수만 조하대에 서식하는 대형저서동물의 군집을 분석하여 방조제 건설에 따른 천수만 저서생태계의 변화를 이해하고자 하였다. 생태학적인 변화를 이해하기 위하여 대형저서동물의 분포, 우점종, 시.공간적 변화 그리고 유기물 오염을 분석하였다. 천수만에는 총 252종이 출현하였고, 출현밀도는 $681ind./m^2$이었다. 종 다양도는 모든 계절에서 방조제를 기준으로 만 입구 지역으로 갈수록 증가하는 양상이었다. 천수만 내 연중 우점한 대형저서동물은 송곳갯지렁이로 나타났다. 우점종 출현양상은 종 다양도 그리고 정점별 퇴적물 내 유기물 함량과 상관관계를 갖는 것으로 확인되었다. BPI분석 결과, 방조제 인근 정점에서는 4~5등급으로 유기물 오염이 진행된 것으로 확인되었고, 만 입구 지역에서는 1~3등급으로 상대적으로 유기물 오염이 되지 않은 것으로 확인되었다. SAB-curve 분석 결과, 방조제를 기준으로 만 입구로 갈수록 생태계 전이지역이 감소하는 것으로 나타났다.

This study was carried out to understand the ecological variations of macrobenthos communities by construction dikes in the subtidal zone of Chonsu Bay. This study analyzed the distribution of benthos, the dominant species, spatial and temporal changes of benthos communities and benthic pollutions in the subtidal zone of Chonsu Bay. A total of 252 species of subtidal macrobenthos with a density of $681ind./m^2$ were studied. In all the seasons, the species diversity was found to be higher near the mouth of the bay. For all the seasons of the year, Lumbrineris japonica was found to be the most dominant species. These dominant species were found to have positive correlations with species diversity and sedimentary parameters such as organic content in sediments. Dominant species of benthos as well as species composition and diversity showed spatial and temporal distribution patterns.Benthic Pollution Index (BPI) values estimated for the stations near the embankment were in the 4~5 levels, which indicates that the organic matter has been polluted. And as for the stations near the mouth of the bay, the BPI values were in the 1~3 levels, which indicates that the organic matter has been relatively less polluted. According to the SAB-curve analysis, the number of transitional point stations became less in the mouth of the bay.
