| 摘 要： | 通过对新江实验林场不同密度、不同年龄阶段的樟子松人工林土壤水分进行测定，分析与探讨了樟子松人工森对土壤水分的影响以及涵养水分的能力；不同密度的樟子松人工林土壤水分的垂直分布，生长季节变化规律、历年变化情况、贮水量的差别，樟子松的林分密度。研究结果表明，樟子松人工林土壤水变化受密度制约，适宜的密度为６２５－８３０株／ｈｍ＾２。

| Abstract: | Soil water dynamic, such as vertical distribution, seasonal fluctuation, annual fluctuation and water-storage, was investigated in Pinus sylvestris var.mongolica plantations with different densities and ages. Result showed that soil water dynamic of pinus sylvestris var. mongolica plantation was restricted by stand density. The stand density of the pine plantation which suit to Xinjiang forest farm of Nehe district was from 625 stocks/hm 2 to 830 stocks/hm 2. |
