The vegetation growth of afforested land was studied by numerical classification techniques in the Dry_hot Valleys the Jinsha River, southwestern China. Seven indices that represent the comprehensive nature of vegetation growth were selected as the variables of numerical classification, being tree height, tree diameter at breast height (DBH), total basal area at tree breast height, forest biomass, tree height growth rate, DBH growth rate, and forest net production. Given this condition, the forest productivity of 14 sample plots was classified by a combination of principal component analysis technique with discriminant analysis technique. The result showed that the forest productivity in this area was mostly dependent of the soil parent material/rock types of slopeland. The magnitude of forest productivity for different parent material/rock types was in order: alluvial deposits schist/gravel deposits mudstone.
