这是Nobel 在 Biophysical plant physiology and ecology (1983)提到的计算的重要性:首先自己去计算,有助于我们理解不同环境要素(辐射、温度、空气湿度、土壤湿度)的贡献。所以,我们使用叶片和环境参数的代表性变量(如气孔导度、空气水汽饱和差、边界层导度、土壤水势等)来描述叶片的气体交换和能量平衡。我们也就能理解植物适应环境的现象,更重要的是,认识到我们需要什么样的实验数据来优化未来的计算(对实验设计的帮助)。(Since it's difficult to appreciate relative contributions of the varous factors without first making calculations, we will use representive values for leaf and environmental parameters to describe the gas fluxes and the energy balance of leaves. We can then begin to understand the consequences of certain adaptions of plants to their environment as well to recognize the experimental dada needed for future refinements of our calculations.)
