中心点关键信息动态全球植被模型是解释和预测陆地生态系统对气候变化和其他驱动因素反应的关键工具。他们估计植物生长是通过光合作用供应碳的结果。然而，增长本身是受直接控制的，而不是简单地受可用碳量的控制。因此，目前由光合作用驱动的模型预测，由于大气CO(2)浓度的增加，未来植被生物量将大幅增加，这可能是严重高估的。我们描述了如何利用当前对木材形成的理解来重新制定全球植被模型，这可能对它们的行为产生重大影响。
center dot Key messageDynamic global vegetation models are key tools for interpreting and forecasting the responses of terrestrial ecosystems to climatic variation and other drivers. They estimate plant growth as the outcome of the supply of carbon through photosynthesis. However, growth is itself under direct control, and not simply controlled by the amount of available carbon. Therefore predictions by current photosynthesis-driven models of large increases in future vegetation biomass due to increasing concentrations of atmospheric CO(2)may be significant over-estimations. We describe how current understanding of wood formation can be used to reformulate global vegetation models, with potentially major implications for their behaviour.
