Abstract: Forest fire in Korea bas been controlled by local government, so that it is required to understand the characteristics of regional forest fire occurrences for the effective management. In this study, to analyze the patterns of regional forest fire occurrences, we divided South Korea into nine zones based on administrative boundaries and pet-formed spatial statistical analysis using the location data of forest fire occurrences for 199 1-2008. The spatial dis tributions of fo rest fire were analyzed by the variogram, and the ri sk of forest fire was predicted by kriging analysis. As a result, forest fires in metropolitan areas showed strong spatial correlations, while it was hard to find spatial correlations of forest fires in local areas without big city as Gangwon-do, Chungcheongbuk-do and Jeju island.
