Abstract: Forest fire releases large amounts of emission products into the atmosphere, and this seriously damages the ecological environment, and affects human health.Therefore, it has great significance to conduct the study on forest fire emission products.In this paper, the publications related to the emission productions caused by forest combustion were collected and reviewed, mainly focus on the four emission products (including carbonaceous gas, nitrogen containing gas, PM_2.5 and aerosol), including research contents, emission influencing factors, different estimating parameters of emission. The review indicated that the current researches on the emission products released by forest fire were mainly focus on the emission quantity, impact area, and the factors affecting emission.The main parameters of forest fire emission include burned area, fuel loading, fuel carbon content, combustible efficiency, emission ratio and emission factor, etc. These conclusions will provide good reference for the quantitative study of forest fire emissions.
