摘　　要：土壤是人类赖以生存和文明建设的重要基础资源。作为地球关键带的核心要素,土壤圈是地球表层系统最为活跃的圈层,而且土壤过程是控制地球关键带中物质、能量和信息流动与转化的重要节点。由于土壤的多重功能不断得到重视,传统的土壤概念已经无法全面反应土壤的功能和作用,为此本文提出了土壤安全的概念。土壤安全是一种基于土壤可持续发展目标而提出一种系统战略框架,为土壤资源的可持续利用和保护提供了理论基础。本文重点论述了地球关键带和土壤安全的内涵以及两者之间的差异和紧密关系。此外,还对土壤安全框架下的生态系统服务进行了梳理和总结,最后对面向生态系统服务的土壤安全需求进行了展望。Soil is an important natural resource that humans rely on and civilization is based upon. As the critical component of the Earth＇s critical zone, pedosphere is most active in Earth＇s surface system. Moreover, soil processes are considered as the control point for the flows and transformations of material, energy and information. In wake of the increasing attention to soil＇s multi- functions, traditional soil concept on its functions and roles is being challenged.Therefore, the concept of soil security is proposed, which is a strategic framework with the aim of soil sustainable development, and it can provide guidelines for the sustainable utilization and conservation of soil resources. In this review, the connotations of Earth＇s critical zone and soil security, and the difference and close relationship between each other are discussed. The ecosystem services in the framework of soil security are summarized. Finally, perspectives on future soil security research needs in the context of ecosystem services are proposed.
