| 摘 要： | 采用5株优势木和平均木对比法,在广西、广东、福建、湖南4省(区)7个县的大叶栎天然次生林中,共初选出大叶栎优树66株,优势木330株。经统计分析,确定大叶栎天然次生林中的大叶栎优树选择标准为:其树高应超过优势木平均树高的11%,胸径应超过优势木平均胸径的22%,材积应超过优势木平均材积的64%。该标准适用于大叶栎天然分布区用材林大叶栎优树选择。

| Abstract: | Taking the methods of 5 dominant tree comparison and mean tree comparison, 66 superior trees and 330 dominant trees of Castanopsis fissa were selected out from the natural secondary stand in 7 counties of Guangxi, Guangdong, Fujian and Hunan province. On the basis of statistical analysis, selection standard of Castanopsis fissa superior tree was formulated as tree height, DBH and volume were 11% , 22 % and 64 % respectively higher than mean tree. This selection standard can be used on superior tree selection in Castanopsis fissa natural distribution area. |
