摘　　要：9年生不同立地条件的毛竹实生林新竹平均胸径、平均高之间呈显著差异。立地条件越好,新竹平均胸径、平均高的值越大;虽然新生竹径阶分布符合用材林径阶分布规律,但不同立地条件之间差异不明显;毛竹实生林平均胸径、平均竹高都是前期增长率较大,后期增长率呈下降趋势。New moso culms in 9-year-old seedling forests in different site conditions have remarkable differences in terms of the average DBH and the height. The average DBH and the height of new moso culms are higher in better site conditions. Even though the distribution of diameter grade of new moso culms is accorded with that of timber forest, the difference between different site conditions is not obvious. The average DBH and the height of moso seedling forests increase rapidly in early growth stage but represent the declining tendency in the later stage.
