Abstract: To understand the environmental characteristics of lightning fires and improve forecasting accuracy,based on meteorological data,vegetation,terrain and other basic information,the environment of lightning forest fire in Daxing'an Mountains was analyzed.The results showed that the occurrence of lightning fires had a positive correlation with the thunderstorms and a negative correlation with humidity index.65.29% of lightning fires was occurred in larch forest,and 36.77% of those was occurred in flat slope region,of which 84.99% was occurred in the region of slope 1°-4°,and tended to the region of 200-1300m attitude,in particularly 300-800m.
Key words: Daxing'an Mountain, Daxing'an Mountain, Lighting fire, Thunderstorm
