摘要：木材质量是决定木材适用性的重要因素。间伐与修枝是人工林经营常用的抚育措施,能减少林分密度,降低林分竞争压力,增加光利用率,改善林分结构。合理间伐和修枝对木材质量有影响。该文梳理两种措施对木材物理力学性质、外观质量、微纤丝角、纤维形态和化学性质的影响,探讨两种措施对木材质量的综合影响。间伐和修枝对木材质量的影响机制仍需进行深入研究,包括间伐和修枝引起的风荷载、内源激素和微观结构的变化,以及这些变化对木材的物理力学性质、干缩特性和外观质量的影响。
Wood quality is important factor to determine applicability of wood.Thinning and pruning are com-mon tending measures in plantation management,which can reduce stand density and stand competition pres-sure,increase light utilization rate and improve stand structure.Reasonable thinning and pruning have effects on wood quality.This thesis investigated effects of these two measures on wood physico-mechanical properties,appearance,microfibril angle,fibre morphology and chemical properties,and explored combined effects of these two measures on wood quality.Further research is needed on impact mechanisms of thinning and pruning on wood quality,which included changes induced by thinning and pruning in terms of wind load,endogenous hormones and microstructure,as well as effects of these changes on physico-mechanical properties,shrinkage characteristics,and appearance of woods.
