The altitude that classified stem mainly concentrated was less than 1000m, slope was less than 25°, aspect was south slope, position was at middle and lower, soil depth less than 17cm. The rate of no interconversion was 66.7% among overtopped stem. It should cut the overtopped stem as intermediate cutting.
