총인부하량을 이용한 인공호의 부영양화 평가 = The evaluation of the eutrophication for the lakes by phosphorus loading

다국어 초록 (Multilingual Abstract)

The purpose of this study is to evaluate and to predict of eutrophication in lakes by using Vollenweider-OECD model and total phosphorus concentration and inflow rate which were measurded in 1993 2001. The results of study were as follows.
The annual total phosphorus loading from the watershed was calculated to be 55~195tP/yr at lake Soyang, 221 466tP/yr at lake Taechong, 123~278tP/yr at lake Andong, 57~109tP/yr at lake Seomjin. These are discharged, for the most parts, from population and fishfarm facility.
TP loading on the surface area at lake Soyang was 3.01gP/m²/yr, 2.82gP/m²/yr, 2.84gP/m²/yr, 3.03gP/m²/yr, 2.34gP/m²/yr, 1.78gP/m²/yr, 0.91gP/m²/yr, 0.89gP/m²/yr, 0.86gP/m²/yr, lake Taechong was 6.71gP/m²/yr, 7.25gP/m²/yr, 7.24gP/m²/yr, 6.53gP/m²/yr, 6.50gP/m²/yr, 7.06gP/m²/yr, 7.04gP/m²/yr, 4.05gP/m²/yr, 3.44gP/m²/yr and TP loading on the surface area of lake Andong, lake Soemjin were 5.39gP/m²/yr, 4.47gP/m²/yr, 4.56gP/m²/yr, 4.45gP/m²/yr, 3.33gP/m²/yr, 2.38gP/m²/yr, 2.53gP/m²/yr, 2.46gP/m²/yr, 2.54gP/m²/yr, 4.09gP/m²/yr, 4.10gP/m²/yr, 3.98gP/m²/yr, 3.73gP/m²/yr, 2.80gP/m²/yr, 3.46gP/m²/yr, 3.22gP/m²/yr, 2.19gP/m²/yr, 2.13gP/m²/yr respectively.
The tropic states of four lakes can be assessed as eutrophy because phosphorus loading exceeds the critical phosphorus loading by Vollenweider-OECD model.
