The rare “5.6” large-scale forest fire destroyed the flora and fauna in the northern part of the Greater Hinggan Mountains and also had some impact on the rodent population. After the fire, we successively set up 29 fixed plots in 11 forest farms in the affected areas such as Tahe and Amur. The investigation used the method of clammy nights and once in mid-month to record the number of rats, species, sex, breeding status, food Structure and population age. The results showed that there were 8 species of rodents in the burned area, belonging to the squirrel family, the hamster family and the murine family.
