采用解析木分析方法研究长白落叶松人工林生长过程，结果表明：径级10～15 a生生长较快，20 a生以后趋向稳定；树高15 a生以前生长迅速，20 a生后稳定生长；材积生长从20 a开始到40 a逐年增长，是生长旺盛期，40 a生平均生长量分别较20 a、25 a、30 a生增长了73．5％、41．5％和19．8％。40 a生落叶松每公顷木材产量分别为20 a、25 a生时的220％和169％，产值分别为292％和182％，年产值分别为146％和114％。长白落叶松人工林的培育方向应确定以大径级材为主。%Growth process of Larix olgensis Henry man-made forest was researched by using analytic trees analysis method , results indicated that the diameter class of 10 ~15 a grew quickly , and tended to stabilization from 20 a; The height growth before 15 a was more quickly , and tended to stabilization from 20 a.The volume of wood increased year by year from 20 a to 40 a, which was the vigorous growth period .The average increment of 40 a was 73.5%、41.5%and 19.8%more than 20 a、25 a、30 a, respectively.The timber yield per hectare of 40a was separately 220%and 169%of 20 a and 25 a, and production value was separately 292%and 182%by which annual value of production was 146%and 114%, respec-tively.Breeding direction of Larix olgensis man -made forest would be the large diameter class tree .
