Under globally accelerating rates of ecosystem degradation, maintaining ecosystem function is a priority to avoid loss of valuable ecosystem services. Two factors are important: changes to the disturbance regime (stresses imposed) and resilience of biodiversity and ecosystem functions (the ecosystem's capacity to respond to change). Various attributes at different scales of ecological organisation confer resilience (from individual species to communities at landscape scales), but it is critical to understand how these attributes interact to inform how ecosystem function changes with disturbances that vary in intensity, spatial extent, and frequency. Individual species attributes influence their resistance, while attributes at the landscape-scale influence recovery of communities and function. Understanding resilience to disturbances requires defining the characteristics of a resilient community at multiple scales.
在全球范围内生态系统退化速度不断加快的情况下，维持生态系统功能是优先事项，以避免宝贵的生态系统服务丧失。有两个因素很重要：干扰机制（施加的压力）的变化和生物多样性及生态系统功能的弹性（生态系统应对变化的能力）。不同尺度的生态组织的各种属性赋予弹性（从单个物种到景观尺度的群落），但关键是要了解这些属性如何相互作用，以了解随着强度、空间范围和频率不同的干扰，生态系统功能如何变化。单个物种的属性影响其抵抗力，而景观尺度的属性则影响群落和功能的恢复。要了解对干扰的弹性，就需要在多个尺度上定义具有弹性的群落的特征。
