- The concept of resilience is polysemic (i.e. has multiple definitions) in ecology. Despite various attempts at clarification, its meaning is still hotly debated.
- We propose a broad definition of resilience as ‘the capacity of an ecological system to maintain its identity in the face of disturbance’ and posit that the polysemy of the concept is partly due to the multiple meanings of the term ‘identity’.
- We distinguish four definitions of identity and use the landscape metaphor to represent each of them.
- We draw on four historical uses of the resilience concept in ecology, showing that each of them refers to the conservation of a certain type of identity and therefore corresponds to a particular level of persistence. This work leads to the formulation of four definitions that enlighten the polysemy of the concept in ecology.
- Synthesis. We assert that the various facets of the identity concept shed light on the polysemy of the resilience concept. Drawing on four historical uses of the concept, we propose four definitions of resilience, each one referring to the maintenance of a different type of identity and thus to a different level of persistence of ecological systems.

生态系统的身份和复原力的含义
- 复原力的概念在生态学上是多义的（即具有多个定义）。尽管进行了各种尝试来进行澄清，但其含义仍在激烈辩论中。
- 我们将复原力的广义定义定义为“生态系统在面对干扰时保持其身份的能力”，并且认为该概念的多义性部分是由于“身份”一词的多种含义。
- 我们区分身份的四个定义，并使用景观隐喻来代表它们中的每个。
- 我们利用了复原力概念在生态学中的四种历史用途，表明它们中的每一种都指的是某种类型身份的保存，因此对应于持久性的特定水平。这项工作导致提出了四个定义，这些定义启发了生态学概念的多义性。
- 综合。我们断言，身份概念的各个方面揭示了弹性概念的多义性。利用该概念的四个历史用途，我们提出了四个弹性定义，每个定义指的是维持一种不同类型的身份，因此是指不同程度的生态系统持久性。
