Abstract

우리나라는 산지-도시생활형 국가이면서 수도권 인구 집중화로 개발압력이 높기 때문에, 중 대도시의 산지 인근에 아파트 등 집단 거주지를 개발할 수밖에 없는 인문사회적인 여건을 가지고 있다. 그러나 산지토사재해 연구에 인문사회적인 피해를 다루고 있는 논문은 찾아보기 어렵다. 본 연구는 토사재해의 인문사회학적 위험도를 도출하고 이를 등급을 설정하는 방법론을 개발하는 논문이며 각 건물군을 재분류하여 원단위를 도출하고 GIS분석과정을 거쳐서 예상재실인구수를 도출하였다. 여기에 분석의 오류를 최소화하기 위하여 체류시간을 고려한 가중치와 상주인구 대비 이용인구의 평균 체류시간의 가중치도 함께 적용하였다. 인문 사회적 위험도를 예상재실인구수로 도출한 결과 토사재해 인문사회 위험도는 예상 재실인구수 0, 1~2, 3~7, 8~21, 21이상의 5단계로 구분할 수 있었다. South Korea is one of the mountain-side urbanized countries with the high development demand by population centralization of the Seoul metropolitan region. South Korea has the humanity and social conditions of developing high-dense residential sites in mountain-side urbanized areas of large and medium size cities. However, there is lack of research for humanity and social damage of landslide disasters. This research is to identify humanity and social risks of landslide disasters, and to investigate a method rating the risk. This research computes basic units of buildings by classifying them, and identifies expected building resident indices derived from the GIS analysis process of our research. This research applies weight average staying times considering staying times and resident-user ratios in order to reduce analysis residuals. The five-stage classification of humanity and social risks for landslide disasters is developed the expected building resident indices of 0, 1~2, 3~7, 8~21 and 21+ stages.
