摘要
恢复力被广泛应用于生态学、经济学、社会学、心理学等众多学科。在描述生态系统方面,恢复力有两种相对清晰的描述性定义。一是Holling恢复力,表示系统在不发生状态转一下吸收的最大干扰量;二是Pimm恢复力,表示系统受干扰后恢复至扰动前的速率和时间。生态系统恢复力既可以表示恢复现状,又可以预测恢复趋势,在防灾减灾方面发挥着重要作用。提升生态系统恢复力可减轻灾害发生风险,开展生态系统恢复力评估可提高灾后重建的科学性。进一步探索灾害驱动下的生态恢复力定义,建立灾害生态恢复力评价指标体系以及构建生态恢复力"绝对值"评价方法是未来研究的重点方向。
Resilience was widely used in ecology,economics,sociology,psychology etc.There were two relatively clear definitions of resilience in describing ecosystems.The Holling resilience,indicated the ability of a system to absorb interference without system transitions or qualitative changes;while Pimm resilience was defined as the system recovery speed and as the time required to recover to the original state after interference.Ecosystem resilience could be applied to demonstrate the current state of ecological recovery and to predict the ecological evolution in the future.It played an important role in disaster prevention and reduction.Strengthening the ecosystem resilience can reduce the risk of disaster,and the evaluation of ecosystem resilience can make post-disaster reconstruction more scientific.Three aspects are the directions of ecosystem resilience in future research:the scientific definition of ecosystem resilience driven by disaster,the evaluation indicators of disaster ecosystem resilience and the method for“absolute value”assessment of ecosystem resilience.
