基于生态系统服务的生态安全研究进展

生态安全是全球环境变化背景下人类可持续发展面临的重要问题之一。生态系统服务作为自然环境中人类赖以生存的环境条件与效用，成为人们感知和评价生态系统结构或功能变化的重要指标，同时为研究自然生态与社会-经济两大系统之间的交互作用提供了连接路径。目前，国内外对基于生态系统服务的生态安全研究尚处于起步阶段。在大量查阅国内外相关文献的基础上，总结了生态安全的理论内涵及方法体系，并从基于生态系统服务内在关系和基于生态系统服务拓展的生态安全研究，以及将生态系统服务与生态安全结合应用的综合研究等3个方面系统性梳理了目前国内外基于生态系统服务的生态安全研究进展。结果表明，发展初期的生态安全研究主要基于各种生态系统服务之间的供需关系、权衡/协同关系和服务重要性等内在关系，二者的结合效果能通过耦合生态系统服与生态系统状态指标和相关模型得到改善，近年来将生态系统服务与生态安全结合应用的综合研究在区域规划管理等领域已呈现良好的发展趋势。在此基础上，本文指出了目前研究过程中所存在的一些不足与未来发展的方向，为进一步深入开展生态系统服务与生态安全的耦合研究提供理论依据。

Research progress and prospect of ecological security based on ecosystem services

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.
