摘　　要：本研究提出了辽东山区现有林分类技术标准 ;对商品林经营管理提出了采用里查德生长函数,拟合9参数多形地位指数模型 ,编制落叶松人工林林分密度控制图,进行商品林密度控制 ;在多形地位指数模型基础上 ,引进林分密度指数 ,把编制的落叶松人工林林分密度控制图推导成可变密度收获表 ,对商品林的收获进行预测和控制 ,建立了商品林立地、密度与收获一体化的经营管理技术体系。同时 ,探讨了辽东山区公益林的经营理论与技术措施。The standard of present forest classification and the Chapman-Richards mode of merchantable forest were pointed out in this paper.The polyform site index charts of Pinus sylvestris was compiled with the9parameters of the mode.By combination of site index,density-controlling diagram of artificial stand of Pinus sylvestris was compiled with densith index and was changed into variˉavle-densith yield table,which could forecast and control the harvest for merchantable forest.In addition,the management modes of merchantable and public welfare forest were discussed.
