红松林木生长轮材质预测的研究

STUDY ON THE PREDICTION FOR THE WOOD QUALITY OF GROWTH RING OF KOREAN PINE

生长轮材质预测属于新兴的学科,主要是通过生长轮材质分析法,寻求林木生长中生态条件的变化与木材材质变化的相互关系。本文描述了红松树枝与树干材质的变化过程,以数量化的模式揭示了它们的相关性,为用树枝预测树干材质开辟了新的途径。试材取自辽宁草河口解放林(4株),吉林土们岭张二北沟(4株),每株树木在枝下高处、1/2枝下高、1.3 m胸高处截取厚10 cm圆盘各三个,以此进行生长轮材质分析测定。试验结果借助数量化理论Ⅰ模式,得出综合相关方程。

The prediction for the wood quality of growth ring is a new discipline. It finds out the relationship between the variation of the environmental contion and the variation of the wood quality by the method of analyzing the wood quality of growth ring. the variation process of the wood quality of korean pine stems and branches was described in this paper, and the coherency was presented in quantitative model, it makes a new path for wood quality prediction. Materials, three disks with 10cm thickness, were collected from Caohekou of Liaoning province and Tumenling of Jilin province at the height of first branch, half of the height of first branch and the breast height respectively, at last, analyses and determinations were carried on the wood quality of the growth ring. As a result, the comprehensive correlation equation was obtained by the Model 1 of the quatitative theory.
