초록

본 연구에서는 수질오염총량제의 토지계 발생부하량 산정 방식에서의 지목 단순화로 인한 불확실성을 분석하고, 23 개 중분류 토지피복도를 기존 산정방식에 적용하여 지목 확장을 할 수 있도록 개선하였으며 이를 L-THIA 모형을 이용하여 검증하였다. 진위천 유역에 대하여 지목이 단순화된 기존 방식(시나리오 1)과 23개 중분류 토지피복도를 이용한 방식(시나리 오 2)으로 산정된 TP 부하량을 비교한 결과 기존 방식의 불확실성이 높다는 것이 나타났으며, 시나리오 2에 의한 분석 결과 같은 대지 분류에 속하는 토지피복들에서 T-P 발생부하량의 편차가 3.45 kg/day~56.69 kg/day로 약 16배의 차이를 보였다. 시 나리오 2를 수질오염총량제에 적용할 수 있도록 23개 중분류 토지피복을 지적도 기반 지목으로 매칭하여 TP 발생부하량을 산정하였다(시나리오 3). 개선된 방식(시나리오 3)의 토지계 T-P 발생부하량 산정의 정확도를 검증하기 위해 L-THIA 모형의 결과와 비교하였으며 모형 예측 대비 약 10% 정도로 차이가 매우 적게 나타났다. 본 연구결과는 향후 수질오염총량제의 토 지계 발생부하량 산정의 정확도를 높이는데 있어 기초자료로 사용될 수 있을 것이라 기대된다.

In this study, the uncertainty analysis of present land pollutant load estimation with simplified land category in TMDLs was performed and the enhanced method for land pollutant load estimation with level II land cover consisting of 23 categories was suggested, which was verified by L-THIA model. For land TP load estimation in Jinwi stream basin, the result of comparison between existing method with simplified land category (Scenario 1) and enhanced method with level II land cover (Scenario 2) showed high uncertainty in existing method. TP loads estimated by Scenario 2 for land covers included in the site land category were in the range of 3.45 to 56.69 kg/day, in which TP loads differed by sixteen times as much among them. For application of scenario 2 to TMDLs, Land TP loads were estimated by matching level II land cover to 28 land categories in serial cadastral map (Scenario 3). In order to verify accuracy of TP load estimation by scenario 3, the simulation result of L-THIA was compared with that and the difference between the two was as little as 10%. The result of this study is expected to be used as primary data for accurate estimation of land pollutant load in TMDLs.
