Abstract:

以小黑杨人工林为对象,研究树冠特征对木材性质和生长量的影响。结果表明:树冠特征对木材基本密度影响不显著;对抗弯弹性模量(MOE)和顺纹抗压强度影响显著,对抗弯强度(MOR)影响不显著;对纤维长度、纤维宽度以及纤维长宽比影响不大;对胸高处湿心材、边材影响极显著。MOE、MOR和顺纹抗压强度与冠幅、冠长呈负相关。线性回归方程能较好地拟合顺纹抗压强度与冠幅的关系, R2值达到0. 61;纤维长度、宽度与冠幅、冠长呈一定的正相关;湿心材面积、边材面积与冠幅、冠长呈高度正相关,边材面积与冠幅间存在密切的线性关系,方程的R2值达到0. 78,二次多项式方程能很好地拟合湿心材面积与冠幅的关系, R2值为0. 91。
