Development of resilience-based state-and-transition models

摘要：

Introduction The objective of this paper is to recommend the incorporation of additional resilience concepts into the state-and-transition model ( STM ) framework.Ecological resilience describes the amount of change or disruption that is required to transform a system from being maintained by one set of mutually reinforcing processes and structures to a different set of processes and structures (e.g.,an alternative stable state).In the light of this concept,effective ecosystem management must focus on the adoption of management practices and policies that maintain or enhance ecological resilience to prevent stable states from exceeding thresholds.Therefore,resilience-based management does not exclusively focus on identifying thresholds per se,but rather on within-state dynamics that influence state vulnerability or proximity to thresholds.
