dc.description.abstract가뭄은 다른 자연재해에 비해 지속기간이 길고 규모가 광범위하여 사회·경제적인 피해가 크게 발생한다. 또한 공간적, 기술적, 경제적 및 사회적 특성에 따라 같은 규모의 가뭄이 발생하더라도 피해 규모는 지역별로 상이하게 발생한다. 본 연구에서는 가뭄에 대한 사회·경제적 영향인자를 고려하여 가뭄 취약성 평가를 실시하였다. 충청도 지역을 대상으로 가뭄과 관련된 기존 사례 분석을 통해 영향인자들을 파악하고 주성분 분석을 적용하여 최종 평가인자를 선정하였다. 선정된 인자들에 대한 가중치 산정을 위해서 엔트로피 기법을 적용하였다. 그 결과 충청도에서는 농가인구수, 기초생활수급자수, 상수도요금격차지표, 산업단지면적, 지하수이용량, 1인당가용수자원량, 상수도보급률, 물재정건전성, 생활용수이용량, 농업용수이용량 및 농경지면적이 평가인자로 선정되었으며, 이 중 농업관련 인자가 큰 가중치를 가지는 것으로 나타났다. 또한, 취약성 평가를 수행한 결과 청주시와 당진시 그리고 서산시가 가뭄에 가장 취약한 것으로 나타났다.-
dc.description.abstractDrought is a longer lasting and more extensive disaster than other natural disasters, resulting in significant socioeconomic damage. Even though drought events have same severity, their damage vary from region to region because of spatial, technical, economic, and social circumstances. In this study, drought vulnerability was assessed considering socioeconomic factors. Preliminary factors were identified from the case study for Chungcheong province, and evaluative factors were selected by applying the principal component analysis. The entropy method was applied to determine the weights of evaluative factors. As a result, in Chungcheong province, farm population, number of recipient of basic living, water fare gap indicator, area of industrial complex, amount of underground water usage, amount of water available per capita, water supply ratio, financial soundness for water resources, amount of domestic water usage, amount of agricultural water usage and agricultural land area were chosen as the evaluative factors. Among them, the factors associated with agriculture had larger weights. The overall assessment of vulnerability indicated that Cheongju, Dangjin and Seosan were the most vulnerable to drought-
