Abstract

The particulate matters show high values in winter and spring season, it has a bad influence on the outdoor people. That's why government needs to come up with countermeasures for social weak people like elementary school students. In this paper, new particulate matter stations select ed about elementary schools using spatial analysis. Seoul city areas were divided with 608 hexagon grids(500m), and then implement spatial analysis such as kernel analysis. Finally, new particulate matter stations select through the results of kernel density analysis and point displacement. The results show that, 10 hexagon grids about new particulate matter stations were selected and listed 15 elementary schools including 10 hexagon grids. The 15 elementary schools were including Gangbuk gu, Eunpyeong gu, Guro gu, Dong gu, Geumcheon gu, Dongdaemun gu, Gangdong gu, Songpa gu, Gwangjin gu and Gangnam gu. The results suggests a new management plan direction according to the spatial analysis, result in the process of selecting the measures for the '2018 School Fine Dust Comprehensive Management Measures' announced by the Ministry of Education. Also, this study can be expanded by adding specific buildings as well as the school.

미세먼지는 주로 겨울철과 봄철에 높은 수치를 보이며, 실외 활동이 많은 사람들의 건강에 더욱 치명적이다. 특히 초등학생과 같은 사회적 약자에 대한 미세먼지 대책은 국가적 차원에서 더욱 시급한 과제이다. 이에 본 연구는 서울시를 대상으로 GIS를 활용하여 초등학교를 중심으로 미세먼지 신규측정소를 선정하였다. 서울시 전체를 500m 반경의 헥사곤 격자를 활용하여 608개의 헥사곤으로 구분한 뒤 측정소와 학교에 위치에 대한 공간분석을 실시하였다. 최종적으로 학교 밀집도 분석과 포인트 대치기법을 통한 조건식을 활용하여 신규측정소 지역을 산출하였다. 연구 결과로 총 10개의 500m 반경의 헥사곤 격자를 신규측정소 지역으로 선정하였고 해당 폴리곤에 포함된 15개의 초등학교 명단을 나열하였다. 최종 선정 폴리곤이 포함된 행정구는 강북구, 은평구, 구로구, 동작구, 금천구, 동대문구, 강동구, 송파구, 광진구, 강남구로 나타났다. 본 연구의 결과는 교육부에서 발표한 '2018년 학교 미세먼지 종합 관리 대책'에 근거하여 공간적인 분석 결과에 따른 새로운 관리 대책 방향을 제시하였으며, 대상지를 학교 뿐 아니라 대상 건물을 확장하여 차후 연구의 활용도를 더욱 높일 수 있을 것이라 기대한다.
