随着全球环境变化和社会生态系统研究的出现，检测和理解干扰是生态学中的一个挑战。我们确定了三个领域的研究需要：开发一个灵活的框架，结合社会和生态系统之间的反馈回路，预测是否干扰将改变其他环境驱动程序的脆弱性，并结合在面对全球变化的环境驱动程序的系统敏感性的变化。在本文中，我们回顾了美国长期生态研究（LTER）网络的发现如何影响干扰生态学的理论范式，我们完善了一个框架，用于描述社会生态干扰，解决这三个挑战。通过对跨越不同生物群落的7个LTER站点实施这一框架，我们展示了干扰如何维持或改变生态系统状态，在景观尺度上驱动空间格局，影响社会生态相互作用，并根据其他环境变化导致不同的结果。
Detecting and understanding disturbance is a challenge in ecology that has grown more critical with global environmental change and the emergence of research on social-ecological systems. We identify three areas of research need: developing a flexible framework that incorporates feedback loops between social and ecological systems, anticipating whether a disturbance will change vulnerability to other environmental drivers, and incorporating changes in system sensitivity to disturbance in the face of global changes in environmental drivers. In the present article, we review how discoveries from the US Long Term Ecological Research (LTER) Network have influenced theoretical paradigms in disturbance ecology, and we refine a framework for describing social-ecological disturbance that addresses these three challenges. By operationalizing this framework for seven LTER sites spanning distinct biomes, we show how disturbance can maintain or alter ecosystem state, drive spatial patterns at landscape scales, influence social-ecological interactions, and cause divergent outcomes depending on other environmental changes.
