We compiled information on 26 numerical models, which consider the terrestrial phosphorus (P) cycle and compared them regarding process description, model structure and applicability to different ecosystems and scales. We address the differences in their hydrological components and between their soil P routines, the implementation of a preferential flow component in soils, as well as whether the model performance has been tested for P transport. The comparison of the models revealed that none offers the flexibility for a realistic representation of P transport through different ecosystems and on diverging scales. Especially the transport of P through macroporous soils (e.g. forests) is deficient. Five models represent macropores accurately, but all of them lack a validated P routine. We therefore present a model blueprint to be able to incorporate a physically realistic representation of macropore flow and particulate P transport in forested systems.

我们汇编了有关26个数值模型的信息，这些数值模型考虑了陆地磷（P）循环，并就过程描述，模型结构以及对不同生态系统和规模的适用性进行了比较。我们解决了它们的水文成分之间以及土壤P例程之间的差异，在土壤中优先流动成分的实现以及模型性能是否已针对P传输进行过测试。对模型的比较表明，没有一种模型可以灵活地代表磷在不同生态系统和不同规模上的真实表达。特别是磷通过大孔土壤（例如森林）的运输不足。五个模型准确地表示了大孔，但它们都缺乏经过验证的P程序。
