摘要： Grassland fire is influenced by fire source, combustible and fire environment. Whether combustible accumulate to a certain amount, and there has meteorological conditions which can cause the grassland fire, it depends critically on fire source whether the fire breaking out or not. Grading research on fire source index has significant meaning for regional disaster prevention management. This study selected grassland fire prevention area of Inner Mongolia - East Ujimqin as the study area, using the MODIS Collection 5 Burned Area Product- MCD45 burned area remote sensing products as a data source and using spatial statistics analysis module of ArcGIS10.1 and SPSS as the operation platform, doing research and analysis grassland fire situation, grassland fire time distribution patterns, grassland fire hot and cold spots distribution pattern, between 2000 to 2011. The results of this paper indicate, the northeast of East Ujimqin is the high frequency region where grassland fire occurrence. And the grassland fire occurred mainly in spring and autumn.
