摘要
为了解樟子松(Pinus sylvestris var.mongolica)的生长过程,更好地经营樟子松人工林,在辽宁省彰武县的6块不同林龄樟子松人工林样地内各选择1株标准木进行树木解析,分析樟子松的树高、胸径和材积的生长过程,并对樟子松人工林树木的生长过程进行模拟。结果表明:樟子松树高、胸径和材积总生长量均随年龄的增大而增加,但解析木在各个生长阶段的生长量不同。应用Logistic生长方程对樟子松的树高、胸径和材积生长过程拟合较好,经过检验,樟子松自然生长过程和阶段可通过生长方程间接得出,即拟合模型较科学,可以应用到实际的樟子松林经营当中。
In order to understand the growth process of Pinus sylvestris var.mongolica and better manage Pinus sylvestris var.mongolica plantation,one standard tree was selected from each of six plantation plots with Pinus sylvestris var.mongolica of different ages in Zhangwu County of Liaoning Province.The growth process of tree height,DBH and volume of Pinus sylvestris var.mongolica was analyzed,and the growth process of Pinus sylvestris var.mongolica plantation trees was simulated.The results showed that the total growth of tree height,DBH and volume increased with the increase of age,but the growth amount of analytic wood was different at each growth stage.The Logistic growth equation was used to fit the growth process of tree height,DBH and volume of Pinus sylvestris var.mongolica well.The natural growth process and stage of Pinus sylvestris var.mongolica could be obtained indirectly through the growth equation after testing,that is,the fitting model is scientific and can be applied to the actual management of Pinus sylvestris var.mongolica.
