国内外城市生态空间土壤种子库研究 进展

城市生态空间是城市空间的重要组成部分，能为城 市提供生态服务。在当前生态文明和绿色发展理念下，城市 生态修复相关研究逐渐增多，其中能为城市生态空间植被恢 复提供潜在种子来源，且低成本、可持续、生态效益高的土 壤种子库技术也日益受到关注。以城市绿地、城市湿地、城 市废弃地等主要城市生态空间为对象，论述了城市生态空间 土壤种子库研究进展，重点综述了城市生态空间土壤种子库 特征、影响因素和实践探索，梳理了城市生态空间土壤种子 库技术体系，包括修复模式、技术路线及评价体系。在此基 础上，提出了今后利用土壤种子库技术进行城市生态空间植 被恢复应加强基础科学研究、合适的工艺与方法开发、生态 修复和景观化融合等方面，以期为城市生态空间土壤种子库 研究与应用提供参考与借鉴。

Research Progress of Soil Seed Banks in Urban Ecological Space at Home and Abroad

Urban ecological space is an important component of urban space, which can provide ecosystem services for cities. Under the current concepts of ecological civilization and green development, researches on urban ecological restoration are gradually increasing, among which, low-cost, sustainable and ecologically efficient soil seed bank technology which can provide potential seed source for vegetation restoration in urban ecological space, is also a growing concern. This paper took urban green space, urban wetland, urban derelict land and other main urban ecological spaces as the objects, discussed the research progress of soil seed banks in urban ecological space, emphatically summarized the characteristics, influencing factors and practice of soil seed banks in urban ecological space, and sorted out the soil seed bank technology system in urban ecological space, including repair mode, technical route and evaluation system. Based on this, this paper put forward that the basic scientific research, the development of suitable processes and methods, ecological restoration and landscape integration shall be strengthened if the soil seed bank technology is applied for vegetation restoration in urban ecological space in the future, which is expected to provide reference for the research and application of soil seed banks in urban ecological space.
