Abstract

With the adoption of MCD45 product in a consecutive twelve years, the spatial evolution model of fire behavior in the study area is analyzed and the spatial and temporal variation rule in interannual and seasonal duration is mastered. On that basis and starting from the principle of grassland fire combustion mechanism, the index of the source of fire, the combustible state index and the fire environmental index are built. Through comprehensive analysis the grassland fire danger index is obtained, with the fire danger classified into five levels by using the risk matrix method. To verify the accuracy of the model, the fire point data on March 22nd, 2012 is tested and the accuracy proves to be 71%. The result shows that the grassland fire danger warning method can be applied to warning work in grassland regions and can efficiently improve the accuracy of grassland fire warning, which denotes great practical significance in domestic grassland fire prevention and control work.
