Resilience is a key concept in ecology and describes the capacity of an ecosystem to maintain its state and recover from disturbances. Numerous metrics have been applied to quantify resilience over a range of ecosystems. However, the way resilience is quantified affects the degree to which different trajectories of ecosystem recovery from disturbance are represented as 'resilient', precluding a comparison of disturbance responses across ecosystems and their properties and functions. To approach a broadly comparable assessment of resilience we suggest using a bivariate framework that jointly considers the disturbance impact and the recovery rate, both normalized to the undisturbed state of a system. We demonstrate the potential of the framework for attribution and integration across the various components underlying resilience.
韧性是生态学中的一个关键概念，它描述了生态系统维持其状态和从干扰中恢复的能力。已经应用了许多指标来量化不同生态系统的韧性。然而，韧性的量化方式会影响不同干扰后生态系统恢复轨迹被表示为“韧性”的程度，从而阻碍了对不同生态系统及其特性和功能的干扰响应的比较。为了对韧性进行广泛可比的评估，我们建议使用一个双变量框架，该框架同时考虑了归一化到系统未受干扰状态的干扰影响和恢复速率。我们展示了该框架在归因和整合韧性所涉及的各种组成部分方面的潜力。
