人类活动对水环境的影响，特别是在营养方面的影响，是水资源管理面临的一个重大挑战。政策相关的管理单位（如集水区）的异质性，在环境控制营养源和运输方面，导致需要进行整体管理。然而，目前的战略是有限的，目前的理解和知识，是空间尺度和景观类型之间的转移。这项研究提出了一个空间明确的框架，以支持从土地到水的营养物质的建模，包括环境和空间的复杂性。该框架承认九个同质景观单元，不同的营养物质损失的敏感性水体。通过支持环境虚拟观测站试点（EVOp）云网络基础设施中应用的示范营养模型，展示了该框架的功能。我们展示了使用框架作为管理决策支持工具和进一步发展综合地球化学建模的范围。
Anthropogenic impacts on the aquatic environment, especially in the context of nutrients, provide a major challenge for water resource management. The heterogeneous nature of policy relevant management units (e.g. catchments), in terms of environmental controls on nutrient source and transport, leads to the need for holistic management. However, current strategies are limited by current understanding and knowledge that is transferable between spatial scales and landscape typologies. This study presents a spatially-explicit framework to support the modelling of nutrients from land to water, encompassing environmental and spatial complexities. The framework recognises nine homogeneous landscape units, distinct in terms of sensitivity of nutrient losses to waterbodies. The functionality of the framework is demonstrated by supporting an exemplar nutrient model, applied within the Environmental Virtual Observatory pilot (EVOp) cloud cyber-infrastructure. We demonstrate scope for the use of the framework as a management decision support tool and for further development of integrated biogeochemical modelling.
