[Objective] The objective of the study is to explore the differences in soil physical and chemical properties in different seasons and slope positions in earthquake-stricken slopes after replanting forest species

and to assess the vegetation restoration and to provide the theoretical support for managing the slope. [Methods] According to the conventional methods

this study investigated the changes of soil physical and chemical properties

soil enzymic activity and herb growth

in Leigu Town

Beichuan County

Sichuan Province. The relationships between variations of soil physical and chemical properties and enzyme activities and the effect of vegetation restoration were analyzed. [Results] Soil nutrient levels and vegetation recovery showed no significant differences in different seasons and slope positions

however

they showed significant difference in undamaged natural slope. [Conclusion] In the current treatments and curing conditions

improved physical and chemical properties of soil can affect vegetation restoration. Much more attention needs to be paid to concepts of villagers and human disturbance. Soil and water holding capacity need to be monitored timely

pioneer herbs need to be replanted

and organic fertilizer can be used in the crop growing areas to improve soil fertility.
