Abstract:

Abstract: Data from 252 sample\|plots in the low elevation region of Beijing were used in this research. A site index table of Pinus tabulaeformis plantation was constructed based on the model which made by the statistical relationship between dominant tree height in each plot and the corresponding tree's age. The table was demonstrated to be of high accuracy when tested with three methods: chi-square test, test of falling point and test of height growth increment. Site quality of the 252 plots was evaluated by using the table. The results showed that 63% of the total plots were in the middle site quality level, and the shady slope with thick soil was the best site condition fitting for Pinus tabulaeformis plantation's growth.
