本文回顾了现有的系统弹性方法，并提出了一种量化水资源系统弹性的方案。一般来说，在水资源系统中考虑弹性的三个方面：(1)防止越过性能阈值；(2)扰动后的响应和恢复；(3)适应能力。传统上，这些方面是分开处理的，而不考虑可能的功能关系或相互依赖性。我们认为，系统的适应能力最好被视为弹性的其他两个方面的输入变量，并且只有当性能阈值未超过时才能考虑响应/恢复。由于水资源系统的动态和演变性质，适当考虑不确定性和相关信息，无论是从定义明确的数字数据还是含糊的语言表达中获得的信息，对于更好地理解和适当管理其复原力至关重要。常量……
This paper reviews existing approaches to system resilience, and proposes a scheme to quantify the resilience of water resource systems. In general, three aspects of resilience are considered in water resource systems: (1) that against crossing a performance threshold; (2) that for response and recovery after disturbances; and (3) that of adaptive capacity. Conventionally these aspects are treated separately without considering possible functional relationships or interdependencies. We argue that the adaptive capacity of the system is better treated as an input variable of the other two aspects of resilience, and that response/recovery may be considered only when the performance threshold is not crossed. Because of the dynamic and evolving nature of water resource systems, proper consideration of uncertainty and associated information, whether obtained from well-defined numerical data or vague linguistic articulation, is essential for better understanding and proper management of their resilience.
