The site-index table for P. tabulaeformis plantation in this area was made. Meanwhile, the relations between the growth of the P. tabulaeformis dominant trees and their site factors such as altitude, aspect, slope, form of stope surface, characteristics of soil etc. were analyzed with the multiple linear progressive regression.It was pointed out that the thickness of soil layer and the soil moisture were the limiting factors that affect upon the growth of P. tabulaeformis plantation in Jiulong Mountain area.
