| 摘 要： | 为探讨不同栽植密度对欧洲云杉林生长量的影响，在国有大老岭林场对4～10年（苗龄3年）生欧洲云杉林，在6种密度下的生长状况进行了调查研究，结果表明：虽然不同密度间欧洲云杉林生长优势还未出现显著差异，但从各生长量指标来看，密度1（1 m×1 m）下欧洲云杉生长优势最明显；10年生林木树高、地径、抽梢、冠幅年生长量分别增长了近15.7％，25.1％，35.3％和26.8％。

| Abstract: | In order to study the effects of different planting density on Picea abies growth,this paper chose six different densities for further studying in Dalaoling national forest farm. The result showed：Although the growth difference of different densities of Picea abies was not significant,but Picea abies with density one（1 m ×1 m） grew the best,and the annual increment of height,ground diameter,sprout,crown width for ten years old plant was 1 5.7%,25.1%,35.3%,26.8% higher than the minimum value. |
