图5. 峨眉冷杉成熟林乔木层及其器官碳利用效率(CUE)的影响因子。箭头正负数值为标准化回归系数, 表示正、负效应; 矩形上方的数字为R2, 其反映了某一变量被其他变量解释的方差解释量; 小圆圈表示残差; 双向箭头表示相关性, 其上方的数字表示相关性大小; 图中虚线表示预设路径。
Fig. 5. Influencing factors of carbon use efficiency (CUE) in tree layer and organs of an old-growth Abies fabri forest. Values associated with solid arrows are standardized path coefficients, indicating positive or negative effects. Values associated with the rectangles are R2, indicating the proportion of variation explained by relationships with other variables. Small circles represent residuals. Values associated with two way arrow indicate the correlation. The dotted line indicates the preset path.
