연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

Abstract AI-Helper 아이콘AI-Helper

With land-use (cover) and water quality, the distributional characteristics of epilithic diatom communities were studied with 193 samples from estuaries of Korean peninsula between 2015 and 2016. Of total 394 taxa classified, Nitzschia perminuta (19.6%) and N. inconspicua (14.0%) were the 1st and 2n...

질의응답

핵심어 질문 논문에서 추출한 답변
하구란? 하구는 해수와 담수가 만나는 전이수역으로 (Costanza et al., 1997; Divya et al., 2009) 물리적, 화학적 변화가 심하게 일어나며 이에 따라 담수와 해수 생물의 구성도 다양하게 나타나는 역동적인 생태계이다 (Davies and Eyre, 2005; Divya et al., 2009).
한반도 하구들의 분포별 특징은? 한반도는 삼면이 바다로 둘러 싸여 있으며 좁은 국토면 적에 비해 많은 해안선의 발달로 인해 약 460여 개의 하구역이 형성되어 있다 (Rho and Lee, 2014). 동쪽의 하구는 단조로운 해안지대, 높은 해발고도를 가지며 수질이 양호하며, 남쪽과 서쪽의 하구들은 복잡한 해안선, 심한 조석차, 발달된 갯벌이 특징이다. 한반도 하구는 크게 한강-서해 한강-동해, 금강, 영산강, 섬진강, 낙동강, 제주 등 7개 구역으로 구분된다 (Rho and Lee, 2014).
하구 자정작용의 기능에 영향을 미치는 것은? , 2009). 하구는 자정작용의 기능을 가지고 있으나 자연과 인간의 활동으로부터 발생된 오염물질이 자정작용의 허용치이상으로 유입될 때, 부영양화와 환경 질의 저하가 일어날 수 있다 (Boyer et al., 2002).
