利用章古台沙地樟子松密度试验林8个密度水平、3个林龄段(13、21、32 a)的观测资料,分析了造林密度对沙地樟子松人工林胸径、树高、蓄积量的生长和林分自然稀疏、径阶分布、材种出材量及经济效益的影响。结果表明：综合考虑樟子松人工林能否稳定、可持续地发挥防风固沙功能,确定沙地樟子松人工林的适宜造林密度为1667~2500株？hm-2,最佳株行距配置方式为2 m×3 m。

The effect of planting density on growth of DBH,tree height,growth of volume,natural thinning of stand,diameter distribution,timber yields and economic benefit of Pinus sylvestris var.mongolica were analyzed by using observation data of eight density levels and three forest ages stages (13 years,21 years & 32 years)in the experimental forest on Zhanggutai Sandland.Result shows that considering the stability and sustainable of Pinus sylvestris var.mongolica plantations to play sand-fixing function,the optimal planting density and row-spacing could be determined as 1 667-2 500 trees ?hm-2 and 2 m×3 m,respectively.
