우리나라의 저수지는 어떻게 분류할 수 있는가? | 우리나라 저수지는 이용목적에 따라 농업용, 발전용, 생활·공업용수용, 홍수조절용 저수지로 분류할 수 있으며(Cho and Cho, 2013), 이러한 저수지 용도에 따라서 저수지 전체 및 호안의 지형, 수문, 수질 및 토양 환경에 차이가 나타난다. 특히 우리나라 저수지에서 호안의 환경은 수위변동폭과 수질에 따라서 크게 영향을 받으며 부수적으로 호안 토양의 토성이 중요한 환경 요인이었다 (Cho and Cho, 2013). | |
저수지의 용도에 따라 호안 생태계의 구조와 기능에 차이가 나타나는 예는 무엇이 있는가? | 저수지의 용도에 따라서 수문 관리를 달리하기 때문에 수위변동의 크기와 빈도가 달라지며 이에 따라서 식생을 비롯한 호안 생태계의 구조와 기능에 차이가 나타난다 (Casanova and Brock, 2000). 예를 들면 홍수조절용 저수지는 고도가 높은 곳에 조성되고 규모가 매우 크며 수위변동폭이 크지만 그 빈도가 적은 특징을 보였고, 발전용 저수지는 홍수조절용 저수지에 비하여 규모가 작고 수위변동 폭이 작으나 그 변화 빈도가 매우 높은 특징을 보였다(Cho and Cho, 2013). 또한 저수지의 수질은 저수지의 수심이 얕을수록 체적에 비하여 표면적이 커져서 부영양화에 취약하고 (Yoon et al. | |
부영양화에 취약한 특징을 지닌 저수지는 어디인가? | 예를 들면 홍수조절용 저수지는 고도가 높은 곳에 조성되고 규모가 매우 크며 수위변동폭이 크지만 그 빈도가 적은 특징을 보였고, 발전용 저수지는 홍수조절용 저수지에 비하여 규모가 작고 수위변동 폭이 작으나 그 변화 빈도가 매우 높은 특징을 보였다(Cho and Cho, 2013). 또한 저수지의 수질은 저수지의 수심이 얕을수록 체적에 비하여 표면적이 커져서 부영양화에 취약하고 (Yoon et al., 2003; Kim and Kim, 2010), 수질 관리 목표가 상대적으로 취약한 농업용 저수지에서 부영양화가 심하게 진행되고 있다 (Cho and Cho, 2013). |
