森林群落结构是森林生产力的基础,是森林经济效益的标志。为了探讨最佳的人工林群落结构,找出有效的经营途径,我们于1958年4月在东北林学院帽儿山实验林场老山营林区55林班建立了实验地,开展了研究工作。 本实验采用兴安落叶松(Larix gmelini),分四个组合,每个组合重复两次,二年生 Forest community structure is the basis of forest productivity and is a symbol of the economic benefits of forests. In order to explore the best structure of plantation community and find out the effective operation way, we established the experimental ground and carried out the research work in April 1958 in the Forest Park of Laoshanyama Forest Farm in Maoershan Experimental Forest Farm of Northeast Forestry University. In this experiment, Larix gmelini was used in four combinations, each combination was repeated twice, biennial
