摘要
研究了坡向、土层厚度、草灌覆盖状况对油松人工林天然更新的影响。结果表明,不同坡向、土层厚度和草灌覆盖状况均对油松人工林的自然更新产生影响,而且阴坡和半阴坡比阳坡和半阳坡更适宜油松林幼树的生长,土层厚度越厚油松林幼树的生长状况越好,草灌覆盖度较小时更有利于油松林幼树的生长。
The effects of slope direction,soil thickness and grass cover on the natural regeneration of Pinus tabulaeformis var.mongolica plantations were studied.Result shows that different slope directions,soil thickness&grassland cover all affect the natural regeneration of Pinus tabulaeformis var.mongolica plantation,and the shady and semi-shain slopes are more suitable for the growth of Pinus tabulaeformis var.mongolica.The thicker the soil layer,the better the growth of the young pine trees,and the smaller the grass irrigation coverage is more conducive to the growth of young Pinus tabulaeformis var.mongolica.
