| 摘 要： | 通过破坏性取样和树干、枝条解析，研究了华山松林木的生长过程和分化特点。结果表明，树冠扩张在８龄以后进入速生期，２４龄后逐渐趋于平稳；直径生长在１２龄以后进入速生期；高生长在１０龄以后进入速生期；材积及生物量在１６龄后进入速生期。进入速生期后，林木分化严重，应及时采取抚育措施，以提高华山松林木的生产力。

| Abstract: | Growth process and differentiation features of Armandi pine trees were studied by method of stem and branch analysis,using destructive sampling. The results show clearly that tree crown expansion goes into rapid growing period after 8 years,getting stationary after 24 year,also its diameter growth,height growth,volunle and biomass turn into rapid growing period after 12 a,10 a,and 16 a,respectly.Stems differentiate fiercely during its rapid growing period,and in this period Armandi pine forests should be tended so that their productivity can be improved. |
