冀北次生林3个树种林分生长过程表的编制
Compilation of stand growth table for 3 tree species of secondary forest in north Hebei Province
摘要
Abstract
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 Ⅱsite quality class for 3 tree species are established. It supplies theoretical basis for forest management, such as growth yield prediction.关键词
