摘　　要：以塞罕坝地区华北落叶松人工林为研究对象,在对研究区域内抚育间伐后不同保留密度下华北落叶松人工林林木的生长变化进行系统的研究基础上,综合分析了抚育的效果。运用DPS统计软件对相关数据进行分析研究,确定胸径与冠幅的回归方程,并通过方差分析验证得到其回归效果十分显著,最终确定不同径阶的华北落叶松经营密度的最大理论值。为确定塞罕坝地区华北落叶松人工林合理的经营密度提供理论依据,有利于华北落叶松人工林的健康、持续发展。Larix principis-rupprechtii Mayr. plantation in Saihanba area,as the object of study,is discussed in this article.Based on the systematic analysis on the growth variation of the Larix principis-rupprechtii Mayr. plantation in different densities after intermediate cutting,the cultivation effect is statistically analyzed by using the DPS statistics software to establish the regression equation for DBH and the tree crown size.The variance analysis shows an extremely remarkable effect,with the maximum theoretical value determined in the forest management density of Larix principis-rupprechtii Mayr. plantation in different diameter classes,which provides a theoretical basis for reasonable management density of its plantation and contributes to the sustainable development of Larix principis-rupprechtii Mayr. plantation in Saihanba area.
