Abstract

Landslides occur in Korea every year because it has numerous mountainous regions and approximately two-thirds of the annual rainfall falls in Summer. Therefore, it is important to predict potential areas of landslides and minimize the damage in advance to protect property and human life. Therefore, in the present study, the potential danger areas were extracted from a digital map, digital forest map, digital forest site environmental map, and digital geologic map to estimate the landslide hazard. In addition, the assessment of landslide danger was analyzed by first and second estimations based on the criteria from the Korea Forest Research Institute using a GIS technique, which was finally judged by a field investigation.

본 우리나라는 산지가 많고 하절기에 연 강수량의 약 2/3정도가 집중적으로 발생하기 때문에 매년 산사태에 의한 피해가 발생하고 있다. 재산 및 인명을 보호하기 위해서는 사전에 산사태 발생지를 예측하고 피해를 최소화하기 위한 대책이 요구된다. 따라서 본 연구에서는 산사태 위험 판정을 평가하기 위해서 수치지형도, 수치임상도, 수치입지도, 수치지질도를 활용하여 산사태 위험지역을 추출하였다. 그리고 국립산림과학원에서 제시한 산사태 위험지 판정표를 기준으로 GIS 기법을 활용해 연구지역의 산사태 위험지를 판정을 1차와 2차에 걸쳐 분석하였으며, 현장조사를 통해 최종 위험지를 판정하였다.
