摘要:本文以人工林红松为研究对象,通过生长轮材质分析法,分析了木材碳素储存量分别
与木材各项解剖特征的径向变异规律及相关关系,旨在优化人工林红松高碳素储存量的定向
培育模式。研究结果表明,红松早晚材碳素储存量与早晚材管胞长度、管胞长宽比的拟合度
均很高,呈高度显著的正相关;早晚材碳素储存量与早晚材微纤丝角的拟合度均很高,呈高
度显著的负相关;晚材碳素储存量与晚材管胞直径、晚材胞壁率的拟合度较高,呈较显著的
正相关;早晚材碳素储存量与早晚材管胞壁厚的拟合度均一般,分别呈较显著的负、正相关;
早晚材碳素储存量与早晚材壁腔比的拟合度均较弱,分别呈一定的负、正相关;早材碳素储
存量与早材管胞直径、早材胞壁率的拟合度较差,无明显相关性。这对评价林木的碳素储存
功能及优质经营林木具有重要的指导作用。

Abstract: The paper took the man-planted Pinus koraiensis as research object, analyzed the radial
variation regularity and correlation respectively of wood carbon storage and each wood
anatomical characteristic through the method of growth ring material analysis. It aimed to
optimize the directional cultivating mode of man-planted Pinus koraiensis with high carbon
storage. The research results showed that, the fitting degree of earlywood and latewood carbon
storage and tracheid length, tracheid length-width ratio of Pinus koraiensis was all very high,
respectively had highly significant positive correlation. The fitting degree of earlywood and
latewood carbon storage and microfibril angle was both very high, and had highly significant
negative correlation. The fitting degree of latewood carbon storage and tracheid diameter, tracheid
wall rate was higher, had quite significant positive correlation. The fitting degree of earlywood
and latewood carbon storage and tracheid wall thickness mon, and respectively had quite
significant negative and positive correlation. The fitting degree of earlywood and latewood carbon
storage and wall to cavity ratio was weaker, respectively had certain negativ
