초록

주암호내 복내 홍수조절지에서 침수 식물체가 수질에 미치는 영향을 조사하기 위해 복내 홍수조절지 내에 자생하는 주요 우점종의 분포와 생육특성을 조사하였고, 이들 결과를 토대로 침수식물체의 영양염류 부하량을 조사하였다. 복내 홍수조절지의 전체 면적은 $1,848,568m^2$로 침수전 (5월 15일) 식생의 총 면적은 $1,146,849m^2$이었고, 8월 19일에는 집중강우로 인하여 식생이 서식하는 전체 홍수 조절지가 침수되었다. 침수지역내 우점 식생은 이삭사초, 물억새 및 매자기로 이삭사초가 전체 홍수조절지 면적의 87%를 차지하였다. 식생별 OM 부하량은 이삭사초가 $865,455kg\;area^{-1}$ (87.7%)로 가장 많았으며, 매자기 및 물억새가36,182 (4.0%) 및 $5,882kg\;area^{-1}$ (0.6%)이었다. T-N 부 하량은 이삭사초가 $17,441kg\;area^{-1}$로 전체 부하량 ($19,570kg\;area^{-1}$)의 약 56%를 차지하였고, 매자기 및 물억새가 3.9 및 0.8%를 차지하였다. T-P 부하량은 이삭사초가 87.6%인 $1,842kg\;area^{-1}$로 가장 높았다. 이상의 결과를 미루어 볼 때, 복내 홍수조절지내 주요 침수 식물체는 침수 후 영양염류를 용출하여 주암호의 부영양화를 촉진시킬 수 있을 것으로 판단된다.

In order to properly manage the quality of water in Juam Lake, distributions and growth characteristics of submerged plants in Boknae flood control reservoir were investigated. In addition, the total amount of nutrient load by submerged plants were investigated. The total vegetation area was $1,146,849m^2$ of total flood control reservoirs ($1,848,568m^2$) before flooding. By August 19, all of Boknae flood control reservoir was flooded during rainy season. Dominant plants were MISSA (Miscanthus sacchariflorus), SCPMA (Scirpus fluviatilis) and CRXDM (Carex dimorpholepis) which occupied 87% of all flood control reservoirs. The total amounts of organic matter loads at different submerged plants were great in the order of CRXDM ($501,642kg\;area^{-1}$) > SCPMA ($20,987kg\;area^{-1}$) > MISSA ($3,413kg\;area^{-1}$). The total amounts of nitrogen loads by CRXDM, SCPMA and MISSA under different submerged plants were 56%, 3.9% and 0.8%, respectively. The total amounts of phosphorus loads at different submerged plants were on the order of CRXDM ($1,842kg\;area^{-1}$) > SCPMA ($78kg\;area^{-1}$) > MISSA ($14.8kg\;area^{-1}$). Therefore, the results of this study suggest that organic matter, T-N and T-P in water quality of Juam lake were strongly influenced by submerged plants in flood control reservoir.
