VARIATION PATTERN OF WOOD PROPERTIES OF NATURALCUNNINGHAMIA LANCEOLATA

In thes paper, the variation pattffe of wood Prpebo was edied for natural Cunninghamia lanceolata. The mathematical models of property were obtained on tracbeidlength, microfibril angle, late wood percdsgn, growth ring width and growth ring dsisity in the radial direction. The interrelation were analynd between tracheid length and microfibril angle. The result can provide sciatilic theory basis for wood utilhaion and early prediction of wood properties .

天然林赤松木材材质变异规律的初步研究

用生长轮材质分析方法研究和分析了天然林赤松木材材质的变异规律．得出了管胞长度、管胞宽度、管胞长宽比、生长轮基本密度、生长轮宽度、晚材率、生长率7项材性指标径向变异规律的数学模型。相关性检验表明,多数材性指标均与生长轮有显著相关性。
