Facing a human-dominated world, ecologists are now reconsidering the role of disturbance for coral reef ecosystem dynamics. Human activities alter the natural disturbance regimes of coral reefs by transforming pulse events into persistent disturbance or even chronic stress, by introducing new disturbance, or by suppressing or removing disturbance. Adding these alterations to natural disturbance regimes will probably result in unknown synergistic effects. Simultaneously, humans are altering the capacity of reefs to cope with disturbance (e.g. by habitat fragmentation and reduction of functional diversity), which further exacerbates the effects of altered disturbance regimes. A disturbance that previously triggered the renewal and development of reefs might, under such circumstances, become an obstacle to development. The implications of these changes for reef-associated human activities, such as fishing and tourism, can be substantial.
面对一个由人类主导的世界，生态学家们如今正在重新思考干扰对珊瑚礁生态系统动态变化的作用。人类活动通过将脉冲事件转变为持续干扰甚至长期压力、引入新的干扰或抑制或消除干扰，改变了珊瑚礁的自然干扰模式。将这些改变叠加到自然干扰模式上可能会导致未知的协同效应。同时，人类正在改变珊瑚礁应对干扰的能力（例如通过栖息地破碎化和功能多样性的减少），这进一步加剧了干扰模式改变所带来的影响。在这种情况下，一种以前能引发珊瑚礁更新和发展的干扰可能会成为发展的障碍。这些变化对与珊瑚礁相关的人类活动（如渔业和旅游业）的影响可能是巨大的。
