Abstract: In order to explore the distribution situations of physical and chemical characteristics of different woodlands damaged in Jiuzhaigou earthquake and further improve the rationality of the rapid restoration model of forest-grass vegetation in the damaged habitat, the soil physical and chemical properties of different plots were analyzed according to the degree of earthquake damage in the study area. The results showed that: (1) The soil bulk density first decreased and then increased with the increasing degree of earthquake damage. (2) The contents of available phosphorus and ammonia nitrogen are positively correlated with the degree of earthquake damage, while the contents of available potassium and nitrate nitrogen showed the opposite pattern. Therefore, targeted soil improvement should be carried out according to the soil physical and chemical properties of different earthquake-damaged plots, in order to improve the recovery speed of forest-grass vegetation restoration, and enhance the supporting conditions of soil fertility in various restoration models.
