Spatial and temporal analysis of fires in Serbia for period November 2000-August 2013 has been performed to investigate whether spatial relationships exist among fire data. MODIS active fire data were used as fire locations. On such data, different tools of spatial analysis and spatial statistics were used, to determine if there is any spatial relationship. Analysis included data screening, identification of land cover of fire locations, aspect, slope, elevation and solar radiation for each location. Later, different spatial statistics tools were executed against fire locations data, including Getis-Ord Gi* Hot Spots, Global Moran’s I Spatial Autocorrelation, Anselin Local Moran’s I Cluster and Outlier, Ordinary Least Square linear regression and Geographically Weighted Regression. Fire radiative power was used as dependant variable, while terrain morphology and solar radiation were used as explanatory variables. Results shows hot spots of fires in Serbia, and indicates that there is strong relationship between fire radiative power on one side and terrain morphology, land cover, solar radiation and spatial distribution on other side. These analysis have highlighted areas with very intensive fire use associated with land management practices.
