本文详细论述了长白山阔叶红松林内六个主要树种的年龄结构和更新策略。它们明显地表现了二种更新策略。红松(Pinus koraiensis)、水曲柳(Fraxinus mandshurica)、蒙古栎(Quercus mongolica)属于间断更新类型,紫椴(Tilia amurensis)、色木械(Acer mono)、春榆则属于连续更新类型。并对六个主要树种的耐荫性加以讨论,初步提出其耐荫程度由弱至强为:蒙古栎→水曲柳→红松→春榆→紫(?)→色木槭. This article discusses in detail the age structure and regeneration strategy of six major tree species in the broad-leaved Korean pine forest in Changbai Mountain. They clearly demonstrate two update strategies. Pinus koraiensis, Fraxinus mandshurica and Quercus mongolica belong to intermittent renewal type. Tilia amurensis, Acer mono and spring elm belong to the continuous regeneration type. The shade tolerance of the six major tree species was discussed. The degree of shade tolerance of the four main tree species was preliminarily raised from weak to strong as: Quercus mongolica → Fraxinus mandshurica → Korean pine → Spring elm → purple (→) → Seleia.
