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.
