Abstract:Ecological security is one of the primary problems that human is facing in the context of global environmental changes. Ecosystem services, as a significant perception index in the variation of the ecosystem structure and functions, provided a path to connect the nature ecosystem and the society-economy system in the background of human-earth coupling. Although the theory and application of ecosystem services have made great progress in recent years, the studies of ecological security based on ecosystem services are still with large uncertain. In this study, we review the research progress of ecological security based on ecosystem services from three aspects as following:the ecological security research based on the intrinsic relationships among various ecosystem services, and on the combination of ecosystem services and other models or indexes, as well as the application study of the integration between ecological services and ecological security in the regional planning and management. The results show that the research on ecological security in the preliminary stage were mainly refer to the supply and demand relationship, the trade-off/synergy analysis and the importance analysis among various ecosystem services. The development of ecological security study could be significantly improved by combining ecosystem services with ecosystem status indicators and related models. In recent years, the comprehensive research on the combination of ecosystem services and ecological security was constantly being applied in other fields and has especially shown a good development trend in the field of regional planning and management. On this basis, some deficiencies in current research are pointed out, and some challenges and research directions are also suggested to provide a theoretical basis for further research on the coupling of ecosystem services and ecological security.
