摘　　要：根据测定的不同密度侧柏林的每木胸径,绘制不同密度侧柏林的径阶分布曲线。结果表明,密度为10335株/hm2的侧柏林需要尽快进行间伐,以减少林木之间的竞争。根据侧柏人工林胸径和冠幅的相关关系,编制了适宜的经营密度表,为徐州人工侧柏林的经营管理提供了理论依据。According to every wood diameter at breast height(DBH) of the Different density of Platycladus orientalis forest,distribution curve of the DBH was charted, indicating the forest of 10 335 trees /hm^2 must be thinned in order to diminish competition between trees.A favorable management density criterion was tabulated according to the relationship between the DBH and crown width of the plantation,providing theoretical basis with practical guidance of management for the Platycladus orientalis plantation in Xuzhou.
