Mathematical Modelling of Terrestrial Ecosystems

需要基于过程的生态系统模拟模型来预测气候和土地利用变化下陆地碳、水和养分循环以及温室气体(GHG)交换的变化。我的研究计划旨在通过构建和测试自然和管理生态系统的数学模型(生态系统)来满足这一需求。 该模型与其他此类模型的不同之处在于其过程的全面性和它们所表示的细节。这一细节允许从基本的化学计量学、能量的能量学和动力学、来自基础理论的C、N和P转化以及独立的、严格限制的实验来模拟生态系统过程。因此，该模型将组成学科(生物气象学、植物生物学、土壤生物学、土壤物理学、土壤化学、农学)的基本研究成果纳入对复杂生态系统行为的研究。其组件过程的细节允许模式在小的时间和空间尺度上运行，例如，针对来自涡旋协方差塔的二氧化碳和能量通量进行良好约束的模式测试所需的。这一模型实现了目前生态系统模型中使用的方法和技术的许多进步。这些进展在同行评议期刊上的80多篇科学出版物中得到了记录。

Process-based ecosystem simulation models are needed to predict changes in terrestrial C, water and nutrient cycles and in greenhouse gas (GHG) exchange under changing climate and land use.  My research program is intended to meet this need by constructing and testing a mathematical model (ecosys) of natural and managed ecosystems. This model is distinguished from other such models by the comprehensiveness of its processes and the detail to which they are represented. This detail allows ecosystem processes to be modelled from the basic stoichiometry, energetics and kinetics of energy, C, N and P transformations derived from fundamental theory and independent, well-constrained experiments. The model thus integrates basic findings from component disciplines (biometeorology, plant biology, soil biology, soil physics, soil chemistry, agronomy) into the study of complex ecosystem behaviour. The detail of its component processes allows the model to function at the small temporal and spatial scales needed for well-constrained model tests against, for example, CO2 and energy fluxes from eddy covariance towers. This modelling implements many advances in approaches and techniques currently used in ecosystem modelling. These advances are documented in over 80 scientific publications in peer-reviewed journals.
