摘　　要：本文以吉林省汪清林业局红松过伐林为研究对象,利用解析木数据,分析红松单木胸径、树高、材积的生长过程,并选择曲线进行了拟合。结果表明:红松胸径连年生长量在90年时达到最大值,树高连年生长量在80年出现最大值,材积的连年生长量在110年以前不断增加。胸径的最优生长方程是y=-1.0199+0.0375A+0.0014A2,树高的最优生长方程是y=0.0702+0.0600A+0.0006A2,材积的最优生长方程是y=1.7×10-9A4.2589。The research objects were Pinus koraiensis trees in natural forests in Jingouling Forest Farm, Wangqing Forest Bureau, Jilin province. The author analyzed growth process of diameter at breast height（DBH）, height and volume, and then gave appropriate growth curves based on stem analysis data of 61 single Pinus koraiensis trees. The result indicated that annual growth of DBH appeared the maximum value in 90 years, annual growth of height appeared the maximum value in 80 years, and annual growth of volume kept increasing before 110 years. The optimum growth equation of DBH was y=-1.0199＋0.0375A＋0.0014A^2. The optimum growth equation of height wasy=0.0702＋0.0600A ＋0. 0006A^2. The optimum growth equation of volume was y= 1.7×10^-9A^4.2589
