This review considers the cascade of events that link injuries caused by plant pathogens on crop stands to possible (quantitative and qualitative) crop losses (damage), and to the resulting economic losses. To date, much research has focused on injury control to prevent this cascade of events from occurring. However, this cascade involves a complex succession of components and processes whereby knowledge on crop loss generates entry points for management. Proposed here is a framework linking different types of knowledge on crop loss to a range of decision categories, from tactical to strategic short- or long-term. Important advances in this field are now under way, including a probabilistic treatment of the injury-damage relationship, or analyses of the sources of uncertainty attached to some components of the decision process. Management of injury profiles, rather than individual injuries, and shifts in dimensionality of crop losses are anticipated to contribute to the design of sustainable agricultural systems, and address global issues concerning food security and food safety.

作物损失的量化和建模：目的回顾。

这篇综述考虑了一系列事件，这些事件将作物病原体对植物病原体造成的伤害与可能的（定量和定性的）作物损失（损害）以及由此产生的经济损失联系起来。迄今为止，许多研究都集中在伤害控制上，以防止此类事件的发生。但是，这种级联涉及一系列复杂的组件和过程，因此有关作物损失的知识为管理创造了切入点。这里提出了一个框架，该框架将关于作物损失的不同类型的知识与从战术到战略的短期或长期的一系列决策类别联系起来。该领域正在取得重要进展，包括对伤害-损害关系的概率处理，或对决策过程某些组成部分附带的不确定性来源的分析。
