초록

청정한 물환경에 대한 기대가 높아지는 시대에서, 관리가 쉽지 않은 비점오염원에서 발생하는 오염부하량을 산정하여 합리적인 국토관리를 도모할 수 있는 기초자료를 제시하였다. 연구는 2개소의 밭경작지를 대상으로 하였으며 고구마와 벚나무를 재배하는 비점오염원으로 각각 3년 동안에 걸쳐 강우사상을 모니터링 하였다. 오염부하량에 영향을 미치는 가장 중요한 인자는 강우량으로 50 < rainfall (mm)의 강우사상에서는 100% 강우유출량이 발생하여 오염물질을 발생하였다. 그러나 30 < rainfall (mm) ${\leq}50^a$와 10 < rainfall (mm) ${\leq}30^b$에서는 강우유출수에 의한 오염부하에는 작물의 재배방법과 토양의 특성 등이 결정인자로 작용되어, 작물성장이 현저한 벚나무경작지에서 강우유출수 발생빈도는 a : 60%, b : 5%로 고구마경작지에서의 강우유출수 발생빈도보다 낮았으며, 이로 인해 오염부하량도 적었다. 반면, 고구마경작지에서의 강우유출수 발생빈도는 a : 80%, b : 15%로 나타났다.

The management of non point sources was marked by the need for clean water environments. It was proposed the fundamentals to promote the reasonable land management in this study. We monitored rainfall events at two non point sources with different crop cultivations such as a sweet potato and a cherry tree for three years. Because the most important factor was rainfall, the rainfall runoff and pollutant loads were generated 100% in the case of rainfall ranges with 50 < rainfall (mm). However the frequency of rainfall runoff was interacted with the crop cultivation and soil characteristics in the case of rainfall ranges such as 30 < rainfall (mm) ${\leq}50^a$ and 10 < rainfall (mm) ${\leq}30^b$. The frequency of rainfall runoff was a : 60% and b : 5% in the cherry tree cultivation with growing significantly and pollutant loads were lower than that of the sweet potato cultivation. Meanwhile the frequency of rainfall runoff was a : 60% and b : 5% in the sweet potato cultivation.
