【摘要】 应用逐步回归方法分析表明：树皮厚、割宽、冠幅、采脂年数、分枝角、树龄、胸径、侧枝粗度等8个因子是影响马尾松产脂力的主导因素，它们与日产脂量存在着极显著的线性关系，可用这8个因子对马尾松日产脂量进行预测．本文拟合出马尾松产脂力最优预测预报方程，其复相关系数为0．703，呈显著水平．更多还原

【Abstract】 In the paper by multiple regression analysis, the characters of regression significance to yield quantity of resin were shown, and also regression equation was made. The results showed those characters such as bark thick, sever width, crown, sever ages twig angle, tree ages, diameter and twig thick were important factors to influence the yield quantity of resin for masson pine (Pious massoniana Lamb. )variance ananlysis of multiple regression equation is of significance, and the complex correlated coefficience is 0. 703.更多还原
