图4 2018-2020年广西红锥累积日径向变化量、树木水分亏缺量、径向生长量及径向生长速率。C为由零生长(ZG)模型计算的径向生长量日总和(Zweifel, 2016)。D为Gompertz函数模拟的红锥树干径向日生长速率。阴影部分表示平均值的标准误。

Fig. 4 Cumulative daily stem radius variations (SRV), tree water deficit (TWD), daily growth-induced irreversible stem expansion (GRO_rate) and daily stem growth rates of Castanopsis hystrix from 2018 to 2020. C, Daily sums of growth-induced irreversible stem expansion calculated from a zero-growth (ZG) model (Zweifel, 2016). D, Daily stem growth rates of C. hystrix modeled with a Gompertz function for the years 2018-2020. Shaded areas indicate the standard error of the mean.
