图3. 模拟增温对根系总生物量(A)、细根生物量(B)、粗根生物量(C)、根冠比(D)的影响与增温幅度、增温年限、增温方式、生态系统类型的关系。右侧数字代表样本量, 误差线代
Fig. 3. Effects of simulated warming (ln RR) on total root biomass (A), fine root biomass (B), coarse root biomass (C) and root:shoot ratio (D) in relation to the magnitude, duration and method of warming and ecosystem types. The values within the graphic panels show the sample sizes for each of the variables. Error bars represent 95% confidence intervals. Solid circles represent significant warming effects (p < 0.05), and hollow circles indicate insignificant warming effects. OTC, open top container.
