摘要

Based on a comprehensive and systematic analysis of the temporal and spatial distribution,periodic changes,and influencing factors of forest fires in Inner Mongolia,through fixed-point observations and experiments on the ground,forest combustibles are divided into the ground litter layer,ground standing litter,and living plants.The combustibles are divided into various grades according to their load,dryness and combustibility.By determining the influencing factors of each combustible grade,a forecast model of the combustibility grade of combustibles is established.The forecast model has been widely used in the mid-and long-term forecast model of fire danger grade,and the accuracy rate of the fall area forecast through back-generation fitting verification is above 88.43%.
