갯벌의 특징은 무엇인가? | 갯벌은 담수와 해수의 교환이 활발히 이루어지는 곳으로 복잡한 퇴적 및 생태환경이 나타나며, 이러한 환경은 다양한 해양생물의 서식지이자 블루카본의 새로운 가치로 대두되고 있다(Murray et al., 2014). | |
갯벌에서 나타나는 환경적 문제는 무엇인가? | , 2014). 하지만 연안개발정책으로 인해 무분별한 개발로 면적 감소와 해안선 변화 등 급격한 환경 변화가 발생할 뿐만 아니라, 발전소의 온배수 배출, 유류유출, 갯끈풀 침입 등 갯벌 환경 오염원 유입으로 바지락 폐사 및 저서생물 변동과 같은 갯벌 어장환경이 악화되고 있다(Choi et al., 2019;Lee et al. | |
객체기반분류법이 분류정확도 향상을 위한 효율적인 분류 방법인 이유는 무엇인가? | , 2012). 또한 래스터 뿐만 아니라 벡터 등자료도 적용가능하기 때문에 분류정확도 향상을 위한 효율적인 분류 방법이다(Kim and Yeom, 2012). 따라서 4 m 공간해상도를 갖는 IKONOS 위성영상과 객체기반 분류 방법을 사용하여 갯벌 퇴적물 분포를 효과적으로 분류할 수 있었다. |
