    摘要:土壤圈是地球表层系统最为活跃的圈层,是连接大气圈、水圈、岩石圈和生物圈的核心要素。但与大气、水体等环境问题相比,由于土壤问题更具隐蔽性和滞后性,长期以来一直未得到足够重视。在充分认识土壤安全概念及城市绿地土壤安全重要性的基础上,分析城市绿地土壤安全受到的胁迫及成因,介绍近年来项目组开展的提升城市绿地土壤安全的生态技术研究,并对未来城市绿地土壤生态安全维护进行展望,旨在唤起公众对土壤安全的重视。

    Abstract:Pedosphere is the most active and vital sphere of the Earthsurface system, and is the core element connecting the atmosphere, hydrosphere, biosphere and lithosphere. However, its importance has not been paid enough attention, because soil environment had a higher elusiveness and hysteresis when compared with air and water environment. Based on the full understanding of the concept of soil security and its importance for urban green space, stress being pushed and reasons were analysed in the paper, and the technical measures improving soil security of urban landscape that have been studied in recent years were then summarized, and the maintenance of soil security of urban landscape in the future was prospected lastly. The aim of the paper is to arouse public attention to soil security.
