Abstract

The continuous social development has led to increasing pollution in lakes. This study proposed the LVRI (Lake Vulnerability Resilience Indicator) based on the vulnerability assessment of climate change for an environmental risk assessment in lakes sufferign water pollution in an integrated aspect of the characteristics in lake watersheds. A total of 11 representative assessment factors were selected and constructed for 6 lake basins in the Geum River Watershed to calculate the exposure, sensitivity and adaptation indicators in a vulnerability assessment classification system. The weight coefficients for assessment factors of the LVRI were also calculated using the Entropy method. This study also compared the rank results of the lake environmental risk with/without the weight coefficients of assessment factors for the practical application of the proposed lake environmental risk assessment method. The lake environmental risk results estimated in this study can be used for long-term water quality analysis and management in lakes.

지속적인 사회발전으로 인하여 호소의 수질오염이 악화되고 있다. 호소의 특성 및 유역의 전반적인 측면에서 수질오염에 따른 호소의 취약성을 평가하기 위해, 본 논문에서는 기후변화 취약성 평가를 이용하여 호소 취약성-탄력성지수(LVRI)를 산정하였다. 금강 수계의 6개 호소에 대하여 취약성평가로 분류되는 3개의 주요 인자인 노출, 민감도, 적응능력을 대표하는 총 11개 세부평가항목들은 선정하였다. 또한, 엔트로피(Entropy) 방법에 의한 가중치를 산정하여 호소 취약성-탄력지수를 산정하였다. 제안된 호소의 취약성 평가방안의 활용성 검토를 위해 가중치 적용 유 무에 따른 취약성 우선순위를 비교 검토하였다. 본 논문에서 선정된 호소의 취약성 우선순위는 장지적인 수질분석 및 수질관리에 도움이 될 것으로 판단된다.
