Abstract: In this study, 514 height-age data of 71 sample plots of cork oak natural secondary forest in the northern region and 58 stem analysis sample trees which were average dominate trees were used to establish site index table. The model lgH=-0.205 9+0.770 0lgA was selected as oriented curve from 12 mathematical models. The datum age was 50 years. Exponential distance was 2 m. Six site index curves(7-17 m)of Quercus variabilis natural secondary forest were developed by using the method of standard deviation adjustment. Tested by correlation coefficient, fit significance and forecast accuracy, the results showed that the site index table had promising precision, and it could be used on Quercus variabilis natural secondary forest site evaluation.

Key words: Quercus variabilis, natural secondary forest, site index table, site quality, north China, growth model
