The spatial variability of vegetation coverage, height, root depth and breadth distribution, aboveground and belowground biomass, and biodiversity were measured on different slope position and exposure of excavated rock soil surface after vegetation restoration by spray seeding technique and incorporation with extra soil. The results showed that significant difference of vegetation coverage variability existed on different slope positions, in the same slope, the value rank as: down-slope(87%)>up-slope( 31%)>mid-slope(190o)along the same slope. Slope position has significant effects on vegetation cover, height and Pielou evenness of plant communities, the effects on root depth and breadth, aboveground and underground biomass, Marglef species richness and Simpson abundance were in- significant. Slope aspect also has significant effects on Pielou evenness index of plant communities, the rank of spatial variability is western-slope>northern-slope>southern-slope>eastern-slope, no significant effects on vegetation cover, height, root depth and breadth, aboveground and belowground biomass, Simpson diversity and Marglef abundance were detected.
