The Risk Analysis of Grassland Fire Disasters Based on Historical data in Northern China

摘要

Using the historical data of grassland fire disasters in Northern China, we have obtained the law of grassland fire disaster spatiotemporal distribution through statistical methods and calculated the probability value of grassland fire in different risk levels in the provinces of Northern China by employing information diffusion. After research, we got the grassland fire disasters distribution law, the probability value of annual grassland fire disaster as well as burned area ratio under various risk levels. It can provide an advantageous basis for fire fighting department to make an emergency plan and strategic decision to reduce the grassland fire disasters.
