Abstract:
In this study,Larix gmelinii forest burned areas were experienced in different forest types.We investigated the chemical properties of forest soil in an unburned control and burned sites dating 13-year-post-fire in the Great Xing′an Mountains of Northeastern China.This study aimed to provide theoretical basis for the recovery of different types of burned sites.The results showed that the soil pH was higher under three different forest types than in the control while the SOC take the opposite trend.The soil total N and total K were significantly lower under three different forest types than in the control.Fire disturbance has no significant effect on total soil P compared with the control.The soil total P in the different burned sites was basically kept within a range compared with the control.The soil available N,available P and available K were significantly higher under three different forest types than in the control.The soil available N showed a ranking of S-G>S-L>S-R >unburned control.The soil available P showed a ranking of S-R>S-G>S-L>unburned control.The soil available K showed a ranking of S-G>S-L>S-R>unburned control.
