摘要:
 为优化蒙栎次生林的林分结构和抚育间伐技术，以汪清林业局蒙栎次生林为研究对象，基于已有的汪清林业局蒙栎自由树冠幅模型，提出了林木冠幅比数的新概念，通过构建林木冠幅比数与林木竞争压力指数的相关模型CCI=1.07-0.001*CSI，采用林木冠幅比数替代林木竞争压力指数，提出一种简便实用的林木分级新方法，即当林木CCI≥0.77为优势木，CCI∈[0.62，0.77）为亚优势木，CCI∈[0.52，0.62）为中庸木，CCI<0.52为被压木。
Abstract:
 For the optimization of the structure and adjustment of thinning technology of the secondary forest of Quercus mongolica in Wangqing,this article introduced a new concept of crown competition index based on existing crown model of the Q.mongolica free-tree,and a simple and practical new method of forest classification by building the correlation model of crown comparison index and competition stress index,CCI=1.07-0.001 CSI and by substituting crown comparison index for competition stress index.Based on this method,when the forest CCI is more than or equal to 0.77,it was catalogued to dominant tree,when CCI is [0.62,0.77),it is sub-dominant tree,CCI∈[0.52,0.62) is for the mean tree,CCI<0.52 is for pressed tree.
