Abstract Coastal area is a typical, complex area interacted between terrestrial and ocean systems. Catastrophic regime shifts of coastal ecosystem may occur as a result of gradual changing forces exerted by external factors. In this study, we presented an indicator-based framework which includes the land-water-biodiversity (LWB) nexus indices of catastrophe analysis to emphasize resilience of Xiamen, a coastal city of China, associated with implementation of integrated coastal management (ICM). The results demonstrate the changes of equilibria in land, water, and biodiversity subsystems that were divided into three periods (1996–2000, 2000–2012, and 2012–2015). The implementation of several ICMs helped to preserve resilient coastal ecosystems since 1997, which indicates effective guidance of resilient coastal management on coastal land, water and biodiversity. Based on trends of indicator changes, we identified the main indicators controlling catastrophic transformation of the LWB nexus system state, which include built-up area and coastal reclaimed area in land subsystem, seawater quality in water subsystem, and all four biodiversity indices. The identified key drivers to catastrophic regime shifts can help to navigate decision making in resilient coastal ecosystem management. The Xiamen case study provides a systematic and quantitative framework for resilience assessment of integrated coastal management and sustainable development.
