초록

기후변화는 100년 후에 남한의 강수량이 17% 증가할 것으로 예측되었다. 우리나라와 같이 여름철 집중호우가 발생하는 경우는 농경지 토양유실이 많아질 것으로 예상된다. 또한 폭풍을 동반한 국지성 호우는 농경지에 많은 피해를 주고 있기 때문에 이에 대한 영향을 최소화하기 위한 적응계획 수립이 시급한 실정이다. 이에 본 연구는 232개 시군구를 대상으로 농경지 토양유실의 취약성 평가를 실시하였다. 취약성 평가의 기간은 현재는 2000년, 미래는 A1B 시나리오를 기준으로 2020년, 2050년, 20100년에 대한 자료를 취합하였다. 취약성을 평가하기 위해 기후노출, 민감도, 적응능력의 대용변수를 선정하였다. 취합된 자료는 표준화 과정을 거쳐 델파이 조사에서 도출된 가중치를 고려하여 취약성을 산정하였다. 취약성은 현재는 남부지방인 제주도와 경상남도가 취약한 것으로 판단되었으나 미래 취약성은 강원도가 증가 추세를 보였다. 본 연구를 통하여 지자체 단위에서 농경지 토양침식에 대한 기후변화 적응계획을 수립하는데 도움이 되고자 한다.

Due to the climate change in South Korea the annual total precipitation will increase by 17 percent by 2100. Rainfall is concentrated during the summer in South Korea and the landslide of farmland by heavy rain is expected to increase. Because regional torrential rains accompanied by a storm continue to cause the damage in farmland urgent establishment of adaptation plant for minimizing the damage is in need. In this study we assessed vulnerability of landslide of farmland by heavy rain for local governments. Temporal resolution is 2000 year and the future 2020 year, 2050 year, 2100 year via A1B scenario. Vulnerability of local government were evaluated by three indices such as climate exposure, sensitivity, adaptive capacity and each index is calculated by selected alternative variable. Collected data was normalized and then multiplied by weight value that was elicited in delphi investigation. Current vulnerability is concentrated in Jeju island and Gyeongsangnam-do, however, it is postulated that Kangwon-do will be vulnerable in the future. Through this study, local governments can use the data to establish adaptation plans for farmland landslide by climate change.
