摘　　要：本文选取1株苦树风倒木进行了树干解析,分析其胸径、树高、材积的生长量,研究其变化规律。结果表明:树龄10年之前,生长速度较快,树高、胸径和材积随年龄的增长总体呈直线上升的趋势;树龄25年时树高增长缓慢,胸径和材积的增长未出现下降趋势,尚未达到成熟期。The stem analysis was carried out on a blow-down tree of Picrasma quassioides in this paper.The increments of its DBH,tree height and volume were analyzed,and the change rule was studied.The results showed that the growth rate was faster before the age of 10 years,and the tree height,DBH and volume increased linearly with the increase of the age.The growth of tree height was slow at the age of 25 years,the growth of DBH and volume did not show the downward trend,and the tree had not yet reached the maturity stage.
