人工林红松木材碳素储存量与解剖特征的径向变异规律

he 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 was common, 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 negative and positive correlation. The fitting degree of earlywood carbon storage and tracheid diameter, tracheid wall rate was worse, had not obvious correlation. Thus, it had important guiding function to evaluate the forest carbon storage function and manage the forest with high quality.
