Abstract

BACKGROUND: Eutrophication occurs occasionally in reservoirs around lake in summer and early autumn. Lakeside macrophyte which is one of internal pollutants effects on water quality when it is submerged during rainy season. To improve water quality of water supply source in Boknae reservoir around Juam lake, characteristics of nutrient(N, P) uptake and release by submerged plants were investigated. METHODS AND RESULTS: In order to establish the management plan of submerged plants in Boknae reservoir around Juam lake, water level, rainfall, flooding and non-flooding areas, biomass of dominant plants, contents of nitrogen and phosphorus were investigated during 7 months(August, 2010 through February, 2011). Dominant plants were Miscanthus sacchariflorus(MISSA) and Carex dimorpholepis(CRXDM) in Boknae reservoir. Total plant area of Boknae reservoir in August, 2010 was 987,872 $m^2$. In Boknae reservoir, flooding occurred from August until February caused by rainfall during rainy season. The total amounts of nitrogen and phosphorus uptakes by MISSA were 247 and 22 kg/total reservoir area, respectively. By CRXDM, the total amounts of nitrogen and phosphorus uptakes were 11,340 and 1,231 kg/total reservoir area, respectively. The total amounts of nitrogen and phosphorus residues by MISSA were 34 and 11 kg/total reservoir area, respectively. By CRXDM, the total amounts of nitrogen and phosphorus residues were 491 and 68 kg/total reservoir area, respectively. CONCLUSION(S): Total amounts of nitrogen and phosphorus releases in Boknae reservoir were 12,212 and 1,324 kg/total reservoir area, respectively. The results demonstrate that total nitrogen and total phosphorus in water were strongly influenced by submerged plants. Therefore, management plan for submerged plants during rainy season will be needed to improve water quality of water supply source in Boknae reservoir around Juam lake.

주암호내 복내 저수구역에서 서식하는 자생식물체들이 침수시 주암호 수질에 미치는 영향을 파악하기 위하여 복내 저수구역이 침수되기 전인 2010년 8월의 영양염류(질소 및 인) 최대 흡수량과 침수 후 다시 침수이전 수위로 회복된 2011년 2월에 남은 식생의 영양염류 잔존량 차이를 이용하여 산술적인 영양염류 용출량을 산정하였다. 2010년 8월에 침수되기전 복내 저수구역내 식생의 면적은 987,872 $m^2$이었다. 침수전인 2010년 8월에 복내 저수구역내 식생의 분포면적별 T-N의 흡수량은 물억새가 247 kg/total reservoir area, 이삭사초가 11,340 kg/total reservoir area로 분포면적이 넓은 이삭사초의 T-N 흡수량이 물억새에 비해 많았으며, T-P의 흡수량도 1,231 kg/total reservoir area로 이삭사초가 가장 많았다. 침수 후 2011년 2월에 조사된 상부지역 물억새의 T-N 및 T-P의 잔존량은 각각 34 및 11 kg/total reservoir area로 침수 전에 비해 감소하였고, 이삭사초의 T-N 및 T-P의 잔존량은 각각 491 및 68 kg/total reservoir area로 물억새와 비슷한 경향으로 침수 전에 비해 감소하였다. 이상의 결과를 종합하여 복내 저수구역내 식생의 T-N 및 T-P의 총 용출량을 산정한 결과 T-N 용출량은 복내 저수구역 총 식생면적(987,872 $m^2$)당 12,212 kg, T-P 용출량은 총 식생면적당 1,324 kg이었다. 따라서 복내 저수구역내 자생식물은 침수시 수중에서 분해되면서 식물체내 질소 및 인이 용출되어 주암호의 수질오염을 가중시킬 수 있는 한 요인이 될 수 있으므로 호소내 수질개선을 위해서는 저수구역내 식물체의 관리방안이 필요할 것으로 판단된다.
