摘要
随着社会经济的发展,人类对自然生态系统的干扰导致多种生态系统服务的退化或丧失,严重威胁区域生态安全.生态系统服务是生态安全的重要表征,基于生态系统服务的城市生态安全研究可为城市可持续发展提供科技支撑和决策参考.本文在对生态系统服务与城市生态安全的概念界定基础上,梳理了两者间的关系,并从生态系统服务视角,探讨城市生态安全评估、制图与模拟的研究进展,指出存在的不足,提出城市生态安全未来研究的重点方向.即基于生态系统服务流的城市生态安全评估、制图与模拟;多元胁迫下的生态系统服务与生态安全的时空动态;耦合水-能源-粮食系统的生态安全框架构建;构建基于行为主体与生命周期的生态安全评估机制;运用遥感数据、社会经济调查数据以及智慧城市大数据等多元数据,宏微观尺度结合、大数据与小数据融合评价城市内部与外部生态安全,优化城市生态安全格局.
With the development of social economy, human disturbance to natural ecosystems leads to the degradation or loss of various ecosystem services, which seriously threatens regional ecological security. Ecosystem services are an important indicator of ecological security. Cities’ ecological security research on ecosystem services could provide a scientific basis for city sustainable development. Based on the definition of ecosystem services and urban ecological security, this paper sorts out the relationship between the two, and discusses the research progress of urban ecological security assessment, mapping and simulation from the perspective of ecosystem services, pointing out the shortcomings. The focus of future research on urban ecological security: urban ecological security assessment, mapping and simulation based on ecosystem service flow, spatial and temporal dynamics of ecosystem services and ecological security under multiple stress, construction of ecological security framework for coupling water-energy-food systems, construct ecological safety assessment mechanism based on behavioral subject and life cycle, use multi-dimensional data such as remote sensing data, socio-economic survey data and smart city big data, macro-micro scale combination, big data and small data fusion to evaluate urban internal and external ecological security, optimize urban ecological security pattern.
