华北地区栓皮栎天然次生林地位指数表的编制
Establishment of Site Index Table for Quercus variabilis Natural Secondary Forest in North China
摘要
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 OlgA 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.关键词
