Abstract
In order to select an effective and appropriate evaluation method for the marine environmental protection and management, it is necessary to evaluate the present status of environmental conditions and to monitor and regulate the harzadous waste continuously. Among the evaluation methods that use benthic fauna, some graphical methods and biological index methods such as species abundance-biomass (SAB), Rank-frequency diagram (RFD), Abundance-Biomass comparison (ABC), log-normal distribution (LND), and Benthic Pollution Index (BPI) modified by Infaunal Trophic Index were used for the assessments of marine environment in the Inchon coastal area. Even though the graphic methods are convenient for easy glimpse of general trend of environmental condition but because they require sufficient ecological data, those methods do not fit for analysis or comparison of regional and detailed environmental condition. On the other hand, when BPI was applied, it was able to compare the spatial benthic conditions. Through considering the functional aspects of benthic fauna which can not be obtained in the cluster analysis, BPI was made it possible to measure or trace down the source of pollution. In the case of the environmental assessment result analyzed in Inchon coastal area, the north eastern part of Yongjongdo was more influenced by the pollution than the outer area of Inchon. The research indicates that especially Inchon harbor has been greatly affected.
연안역의 환경을 오염이란 관점에서 가장 객관적이고 효율적인 평가 방법을 선정하기 위하여 인천연안역을 대상으로 저서동물군집을 이용한 환경평가 방법인 종-개체수-생물량곡선 (SAB), 순위-빈도 곡선 (RFD), 개체수-생물량 비교법 (ABC), 대수-정규 분포 곡선 (LND), 내서 동물 식성지수를 응용한 저서 오염 지수 (BPI)에 적용하여 환경평가를 실시하였다. 그래프를 이용한 평가방법은 환경상태를 한 눈에 파악 할 수 있는 장점이 있지만, 충분한 생물자료가 요구되기 때문에 지역적으로 또는 세부적으로 비교
