摘　　要：该文利用河北承德地区天然次生林 3个树种 (白桦 ,柞树 ,山杨 )的 710块标准地 ,进行了分类、筛选、研究 ,从中选出符合条件要求的 6 5 3块标准地 ,对各树种的立地分布进行了分析 ,然后对各树种的林分调查因子的生长方程进行模拟 ,并对生长方程进行了检验 ,分别编制了占比重最大的Ⅱ地位级的经验生长过程表 ,为该地区In this paper, using the data of 653 sample plots, which were screened out through classification, selection and study from 710 sample plots of 3 tree species (B. platyphylla,Q. mongolica,P. davidiana) of natural secondary forest in Chengde area Hebei Province, the site quality distributions are analyzed and the growth equations of stand description factors are stimulated and tested. Based on the above, empirical growth tables of II site quality class for 3 tree species are established. It supplies theoretical basis for forest management, such as growth yield prediction.
