摘　　要：以3~6年生俄罗斯花楸幼林为研究对象,通过观察幼林的生长性状,对其生长规律进行研究的结果表明:俄罗斯花楸幼林树高和冠幅指标年平均生长量较为稳定,平均值为0.55 m和17.4 cm。造林6年林分平均树高为2.65 m,年平均生长量为0.55 m,平均胸径为2.70 cm,年平均生长量为0.62 cm。6年生俄罗斯花楸幼林的生长性状在样地间差异均不显著,表明俄罗斯花楸幼林早期生长稳定性较好。从俄罗斯花楸连年生长量来看,树高、胸径和冠幅指标随着栽植时间均逐渐增加,但树高和胸径增加的幅度没有冠幅增加的幅度大,冠幅指标到第6年已达到117.3 cm。The young forest of Sorbus aucuparia from 3 to 6 years old was studied.By observing the growth characters of young forest,the growth pattern of young forest of Sorbus aucuparia was summarized.The results showed that the average annual growth of height and crown width were stable,the average value were 0.55 and 17.4.The average tree height and breast diameter of 6 years old forest was 2.65 m and 2.70 cm.The average annual growth was 0.55 m and 0.62 cm.The young forest in different plots had no significant differences and had good early growth stability.For the annual growth of Sorbus aucuparia,the tree height,breast diameter and crown width have been increased gradually with the planting time,but the increase range of tree height and breast diameter was not as large as that of crown width.The crown width had grown to 117.3 cm.
