摘　　要：研究分析了火炬松管胞形态和木材物理力学特征量的变异规律．得出了管胞长度、管胞直径、管胞长宽比、微纤丝角、生长轮宽度、晚材率、胞壁率和生长轮密度等材性指标变异规律的数学模型，为实现林木定向培育和速生优质制定科学集约经营措施以及材质的早期预测提供科学的理论依据。The variation Pattern of wood tracheid morphology and wood physical mechanics properties of pinus taedaL. was studied in this paper. The mathematical models of the variation pattern of tracheid length, tracheiddiameter, ratio of tracheid length and width, microfibril angle. growth ring width. late wood percentage. cell wallratio and growth ring density were obtained. which can provide the theoretical base of man-made forestintensive management and oriented cultivation as well as the early forecast of wood quality.
