摘　　要：本文通过内蒙古大兴安岭林区兴安落叶松幼、中龄林可变密度收获表编制过程,根据生长理论,建立时间-立地-密度连续型方程,对该树种不同起源、不同立地、不同密度的林木的直径、树高、断面积和蓄积量的生长规律进行了研究,所得结果即反映内蒙古大兴安岭林区兴安落叶松幼、中龄林的现状,又为编制林业数表和采取相应经营措施提供理论根据。The variable density yield table of young and middle age stands of dahurian larch (Larix gmelinii Rupr) in Daxing′anling district were compiled base on the growth theory of Von Bertalanffy. We have developed time-site-density continuous equations and studied the growth and yield of DBH, height, basal area and volume of different origins, sites and densities of dahurian larch. The result reflected the present growth situation of dahurian larch and provided the theoretical basis for constructing forestry tables and taking corresponding management treatments.
