in 5-year planting plots
and
Prunus cerasoides
in 1 –year planting plots.
The similarity among 4 areas were
less than 35%. The height and GBH of tree in
forest restoration area increased with
plot ages. The natural forest profiles s
howed 2 discontinuously canopy layers, while
profile of 9-year planting plots showed
2 continuously canopy layers. The tree density
in forest restoration areas is higher than natural forest, due to density of tree seedling
