摘　　要：土壤种子库的功能对植被系统的存在、发展和变化具有重要意义。土壤种子库拥有重要记忆功能,通过研究其记忆能力可以反映植被发展历史,特别是在追源植被演化过程中具有重要指示作用。土壤种子库的重要作用主要体现在受损植被系统的恢复上,其强大的植被恢复功能一直受生态工作者的重视、并得到广泛应用。正常的植被更新在很大程度上依赖于土壤种子库的潜在植被能力,在干扰作用下土壤种子库决定着植被的演替趋势。在退化植被系统恢复中,重视土壤种子库"捐赠"理论和技术的研究,是发挥和重新构建土壤种子库功能的重要基础。Soil seed banks have an important significance in vegetation systems. Memory is an important function of soil seed banks since it can reflect the history and process of vegetation succession, and be used as a means to trace vegetation development. A main use of soil seed banks is in vegetation restoration, so soil seed banks have been widely used by restoration workers. Normal vegetation regeneration depends on the potential vegetation supply of soil seed banks and that determines the trend of vegetation succession or development. In a degraded vegetation system, the theory and technology of soil seed bank donors should be emphasized in studies as a significant base from which to practice and rebuild soil seed bank function （SSBF） for vegetation restoration.
