摘　　要：以华北地区71块栓皮栎天然次生林标准地和58株平均优势木解析木的514对树高-年龄数据作为编表材料,从12个数学模型中选定lgH=-0.2059+0.7700lgA作为导向曲线,基准年龄为50年,指数级距为2m,运用标准差调整法导出7～17m6条地位指数曲线,最终得到华北地区栓皮栎天然次生林地位指数表。相关系数检验、拟合显著性检验和预报精度检验表明:所编地位指数表精度较高,可用于华北地区栓皮栎天然次生林立地质量评价。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.
