Abstract

This research demonstrates the application of GIS to the selection of the waste landfill site through the case study of a urban area. The estimation factors for the suitability analysis of the waste landfill site were determined. The database was built through collection, input, and transformation of data. The recent land cover classification data and NDVI data which were obtained through processing of satellite imagery were incorporated into GIS data as estimation factors. The relative weights of importance among 2nd category estimation factors were determined by the pairwise comparison method. Also relative weights of 1st category estimation factors which are divided into the social-economical factor and the natural environmental factor were combined with those of 2nd category estimation factors. As the results of this case study, the suitability analysis was conducted in accordance with various estimation criteria. The highest suitability index was obtained in the case where we considered the relative weights of 2nd category estimation factors as different in the viewpoint which regards the social economical factor as important.

본 논문은 도시지역의 폐기물 매립지의 적지선정에 GIS기법을 적용한 사례연구를 제시한 것이다. 폐기물 매립지의 적지분석을 위한 여러 가지 평가인자들을 결정하고 데이터의 수집, 입력, 변환을 통하여 데이터베이스가 구축되었다. 또한 위성영상의 처리에 의해 대상지역의 최근 토지피복 분류와 식생활력도(NDVI) 데이터가 평가인자로서 GIS데이터에 통합되었다. 사회경제적 인자와 자연환경적 인자로 구분되는 1차 분류 평가인자들의 가중치를 이원비교법에 의해 결정된 2차분류 평가인자들의 가중치와 조합하여 분석하였다. 사례연구의 결과, 여러 가지 평가기준에 따른 적합성 분석이 가능하였으며, 사회경제적 인자를 중요하게 간주하는 관점에서 2차 분류 평가인자들의 가중치를 중요도에 따라 다르게 부여한 경우에서 가장 높은 적합도가 얻어졌다.
