樟子松是中国北方地区主要造林树种，影响其林分生长的主导因子之一是密度。研究樟子松生长特性及其与密度的相关性，对引种栽培和林分抚育管理等都有重要意义。选取内蒙古中部地区那日斯台林场为试验地，通过对高密度（>3000株/hm2 ）、中密度（2000~3000株/hm2 ）、低密度（1000~2000株/hm2 ）3个不同密度组被选的8个样地每木检尺和解析木分析，结果显示，各年龄段3个密度组之间在树高生长量上没有大的分化，而在胸径、单株材积和蓄积量具有较大的分化。研究表明，密度对山地樟子松的胸径、单株材积和蓄积量有显著影响，而对树高生长量影响不明显；随着密度的增加，林分胸径和单株材积减少，蓄积增加；20龄高密度组和低密度组胸径总生长量相差10 cm、材积总生长量相差0.9 m3 。密度愈大，材积迅速生长开始期的树龄愈大。

Pinus sylvestris var. mongolica Litv is one of the chief forest species in northern China. To study its growth characteristics and its relation with the stand density is significant to its introduction and cultivation in the north part of China, since stand density is one of the factors that affect its growth. Therefore, the forest stand of P. sylvestris var. mongolica with 3 groups on different densities (>3000 plants/hm2 , 2000-3000 plants/hm2 and 1000-2000 plants/hm2 , respectively) in 8 sample fields are measured and studied in the Naristai Forest Farm in the central part of Inner Mongolia Autonomous Region. The results show that the DBH, individual volume increment and the total volume of the forest stand are significantly affected by the stand density while the height growth is not. In other words, the stand density has a significant impact on DBH, the individual volume increment and the total volume. As the stand density increases, the DBH and individual volume increment are decreasing while the total volume is increasing. The difference of DBH between the high density groups and the low density groups is 10 cm, while the difference of total volume increment is 0.9 m3 . This study also indicates that the higher the stand density, the greater the initial age of the forest stand at which trees begin to grow rapidly.
