Abstract

The purpose of this study is to analyze the spatial cluster characteristics of fire using long-term fire data. For this, fire data which were broke out in the last 40 years were converted into GIS data and spatial analysis was performed at Gangwon-do province's minimum administrative district level. In order to grasp the spatial distribution of the fire, Moran's I, Geary's Ci and Getis-Ord's Gi*, which are methods that analyze the local indicators of spatial association(LISA), were used. By integrating the characteristics of the spatial distribution of fire by integrating the results obtained from each analysis, the advantages of the individual analysis methods were reflected in the study results. As a result of the study, hotspot areas of fire in Gangwon-do was derived out. Among the hot spot areas, some areas, where the fire frequency is higher than the adjacent areas, have been identified. The results of this study can be used as information for predicting the fire hazard area and relocating of fire-fighting facilities in the study area.

본 연구의 목적은 장기적인 화재 발생 데이터를 이용하여 연구지역에서의 화재 발생에 대한 공간적인 군집 특성을 분석하는 것이다. 이를 위해 강원도 읍 면 동 단위에서 지난 40년 동안 발생한 화재 자료를 GIS 데이터로 변환하여 공간 분석을 수행하였다. 화재의 공간적인 군집 특성 파악에는 국지적 공간 연관성을 분석하는 방법인 Moran's I, Geary's Ci 그리고 Getis-Ord's Gi*를 활용하였다. 그리고 개별 분석방법이 지니는 장점을 연구 결과에 반영하기 위하여, 각각의 분석에서 도출된 결과를 통합하여 화재의 공간적 분포 특성을 해석하였다. 연구 결과 강원도에서는 화재 발생의 핫스팟 지역이 존재하였으며, 핫스팟 지역 중에서도 인접한 지역에 비하여 상대적으로 높은 화재 발생빈도를 보이는 지역을 확인할 수 있었다. 본 연구의 결과는 연구지역에서의 화재 발생 위험지역 예측과 소방 시설 재배치를 위한 자료로 활용될 수 있다.
