- W2047338001 abstract "본 연구에서는 낙동강 유역을 대상으로 물리, 화학, 생물학적의 복합적인 평가요소를 이용하여 수생태 관련 기후변화 취약구간을 선정하였다. 먼저 SWAT 모형을 이용하여 A1B 기후변화 시나리오에 따라 각 소유역별로 유출량, 유사량, 갈수량 변화를 모의하였다. 또한 환경부의 수질 측정망과 수생태 건강성 측정 지점이 서로 일치하는 48개 지점을 대상으로, BOD 및 TP 등의 수질 데이터와 IBI, KSI의 수생물 데이터를 평가에 반영하였다. 한편, 미래 기온 상승에 따른 낙동강 유역 하천에서의 수온 상승 폭을 예측하였고, 이로 인한 수생물 서식처 영향을 분석하여 평가에 반영하였다. 각 평가요소를 종합하여 가장 취약한 상위 10개 지점을 제시하였다. 본 연구는 하천 생태복원을 위한 취약구간 평가 및 종합적인 평가 결과를 토대로 각 하천 특성에 맞는 하천 관리 계획을 수립하는데 있어 효과적일 것으로 사료된다. In this study, using a complex of physical, chemical, and biological evaluation factors, the ecological vulnerability to climate change were evaluated at each river in the Nakdong river basin. First, runoff, sediment rate, and low flow discharge changes according to AIB climate change scenario using the SWAT model were simulated. Also, for the assessment of chemical and biological factors, 48 points that water quality monitoring sites and ecological health measurement points are matched with each other was selected. The water quality data of BOD and T-P and the biological data of IBI and KSI in each point were reflected in the assessment. Also, the future rise in water temperature of the rivers in Nakdong river basin was predicted, and the impact of water temperature rise on the fish habitat was evaluated. The top 10 most vulnerable points was presented through a summary of each evaluation factor. This study has a contribution to river restoration or management plan according to the characteristics of each river." @default.
