论文摘要
我们分析了Slomp和Van Cappellen（2007，https://doi.org/10.5194/bg-4-155-2007）的海洋中磷循环的模型。该模型包含四个不同的海洋盆地，其中包括水，碳和氧气周期的相关部分。我们表明，该模型可以从本质上进行分析解决，并且它的行为完全理解而无需求助于数值方法。特别是，我们表明，在模型中，不同海洋储层中的碳和磷浓度都被奴役了深海中可溶性反应性磷的浓度，从而在180,000 y的时间尺度上均衡至平衡，我们表明深海是ocicoxic或osic osic osic osic of ocic of ocic of ocic extip extection tection extection extection，我们决定了一个关键的参数，我们可以确定一个关键的参数。最后，我们研究了此关键参数的值如何取决于模型中包含的物理参数。提出的方法基于应用数学的工具，可用于降低其他大型生物地球化学模型的复杂性。
We analyse a model of the phosphorus cycle in the ocean given by Slomp and Van Cappellen (2007, https://doi.org/10.5194/bg-4-155-2007). This model contains four distinct oceanic basins and includes relevant parts of the water, carbon and oxygen cycles. We show that the model can essentially be solved analytically, and its behaviour completely understood without recourse to numerical methods. In particular, we show that, in the model, the carbon and phosphorus concentrations in the different ocean reservoirs are all slaved to the concentration of soluble reactive phosphorus in the deep ocean, which relaxes to an equilibrium on a time scale of 180,000 y, and we show that the deep ocean is either oxic or anoxic, depending on a critical parameter which we can determine explicitly. Finally, we examine how the value of this critical parameter depends on the physical parameters contained in the model. The presented methodology is based on tools from applied mathematics and can be used to reduce the complexity of other large, biogeochemical models.
