The purpose of this study was to analyze the habitat status and species diversity of benthic diatoms and estimate the applicability of TDI (Trophic Diatom Index) to obtain the basic data for the identification and management of created wetlands in the Nakdong River. We observed a total of 38 familie...

낙동강이란? | 낙동강은 한반도의 남동부에 위치하고 있으며, 태백에서 부산까지 유로 구간으로 약 526km의 길이를 가진다. 국내에서 가장 큰 유역면적을 가진 강이지만(유역면적, 23,817km²), 본류와 지류에 설치한 다목적댐(안동, 임하, 합천, 남강, 영천, 밀양, 운문댐 등)과 하구둑으로 물의 흐름이 인위적으로 조절되는 특성을 가진다(Ha et al., 1998). | |
습지의 이탄층이 주는 효과는? | 어류와 같은 포식자는 수생식물이 복잡하게 구성된 지역 내에서는 포식활동이 제한되기 때문에, 미소갑각류 등의 피식자의 생존과 개체군 증식에기여할 수 있다. 또한 습지의 이탄층은 토양 사이의 간격이 넓어 많은 물을 머금을 수 있어 홍수 등의 방지에 도움을 주며,습지식물은 마을오폐수나 오염물질 정화에 큰 효과를 가진다. 이러한 습지의 중요성으로 인해, 현재 160개국이 국제습지협약(Ramsar Convention on Wetlands)에 가입하여, 전 세계적으로 산포된 2018개의 습지를 보호·관리하고 있다. | |
TDI를 서식환경 및 수질 평가지표로 활용할 때, 습지에서 적용가능성이 매우 낮은 이유는? | , 2005; Shen et al., 2008), 습지는 흐름이 적고 정체수역에 가깝기 때문에 대부분 영양염류 농도가 높다. 그래서 흐름이 지속적으로 유지되어 호청수성 종(Saproxenous taxa)이 출현하는 서식환경이 아니라면, 대부분 높은 TDI 값과 낮은 등급이 산출될 수밖에 없다(Della Bella et al., 2007). |
