不同营林措施对黔中马尾松天然次生纯林生物量的影响
|
摘要
以黔中地区马尾松天然次生纯林为研究对象,实施幼龄林抚育、中龄林间伐及近熟林择伐措施林分与对照林分生物量的对比结果表明:抚育林分的平均木、目标树和林分总生物量分别达到对照林分的1.83、1.59和1.15倍;间伐与择伐林分目标树生物量的年增长量均显著高于对照林分,间伐林分乔木层生物量的增长量与增长率均高于对照林分,抚育增加了平均单株生物量和乔木层总生物量,间伐与择伐对林分目标树生物量和乔木层总生物量的增长均有促进作用,对林下植被生物量的促进作用不明显。
The natural secondary Pinus massoniana pure forest was used as the research object, the comparison of the biomass of tended young stand, thinned middle-aged stand and selective fell near-forest stand with control stands showed that: the average tree, target tree and stand accumulated biomass in the tending reached 1.83, 1.59 and 1.15 times higher of the control. The annual growth of the target tree biomass of the thinned and selective fell stands was significantly higher than that of the control stand; The growth and growth rate of arbor layer biomass in the thinned forest were higher than that in the control forest.Tending could increase the average biomass per plant and the total biomass of the arbor layer; Thinning and selective felling can promote the biomass of the target tree and the growth of the total biomass of the tree layer, but the promote of the biomass of the understory vegetation was not obvious.
