Forest fire is a natural or man- made factor and can change the physical,chemical properties and biological indicators of the soil,and even has great impact on the soil properties and fertilities,as well as the structure and function of the agricultural ecosystem. As China's key state- owned forest,Greater Xing' an mountain region has the vast forest area and high forest coverage rate,which is the important guarantee for the ecological safety of our country. There are more than 500 species of agricultural crops in the abundant forest resources. The main mode of modern agriculture is green farming and breeding industry such as trees,tussah silk,fruit and herbs etc.,in Greater Xing' an mountains. But Greater Xing' an mountain region is the area that the forest fire happened frequently in China. This paper reviewed the effects of fire on forest soil's physical and chemical properties and biological indicators in recent years,with the aim to provide a scientific basis for the vegetation restoration in the burned forest and scientific management of agriculture forest economy.
