使特定林地上的森林产出最多、收益最大,是森林经营者、林学家们长期关心且颇具吸引力的课题。经过林学家们的不懈努力,长期研究,终于揭示了森林生长的数量规律——林分密度效应。林分密度效应有多种表达式,其基本的规律是,林分在同一生长阶段单位面积上的 It is a long-term concern and an attractive topic for forest managers and forest scientists to maximize the output of forests on the specific forest land and maximize the returns. Through the unremitting efforts of forest scientists, long-term research has finally revealed the quantitative laws of forest growth - stand density effect. There are many kinds of expressions for the effect of stand density, and the basic rule is that the stands are in the unit area of ​​the same growth stage
