这一重要的审查介绍了一个模板，链接磷（P）的来源和动员过程中提供的P接收沃茨的有害影响是值得关注的。因此，它是这一特刊的关键介绍性文件。整个过程中描述的“P传输连续体”，以强调跨学科和跨尺度的性质的问题。迄今为止，大多数知识都来自于使用受控实验的P的来源和动员的机械研究，这些实验已经形成了旨在最大限度地减少从农田转移的缓解策略的基础。然而，我们的能力外推这些信息到更大的尺度是有限的，而在复杂系统和分形动力学领域的新概念的进展表明过去的理论框架的局限性，一个贫穷的知识基础。在陆地科学和水生科学中从事不同规模工作的科学家在概念和实际上是分开的，这使情况更加复杂。迫切需要多尺度方法来整合不同的学科，并提供一个平台，以开发机械建模框架，收集新数据和确定关键的研究问题。(c)2005 Elsevier B.V保留所有权利。
This critical review introduces a template that links phosphorus (P) sources and mobilisation processes to the delivery of P to receiving waters where deleterious impact is of concern. It therefore serves as a key introductory paper in this special issue. The entire process is described in terms of a 'P transfer continuum' to emphasise the interdisciplinary and inter-scale nature of the problem. Most knowledge to date is derived from mechanistic studies on the sources and mobilisation of P using controlled experiments that have formed the basis for mitigation strategies aimed at minimising transfer from agricultural fields. However, our ability to extrapolate this information to larger scales is limited by a poor knowledge base while new conceptual advances in the areas of complex systems and fractal dynamics indicate the limitations of past theoretical frameworks. This is compounded by the conceptual and physical separation of scientists working at different scales within the terrestrial and aquatic sciences. Multi-scaled approaches are urgently required to integrate different disciplines and provide a platform to develop mechanistic modelling frameworks, collect new data and identify critical research questions.
