摘　　要：荒漠生态系统是地球上最脆弱的生态系统。近年来,荒漠生态系统保护和恢复的研究已受到广泛关注。土壤种子库作为种子源,在植被恢复过程中起着至关重要的作用。本研究系统回顾了近20年来国内外对干旱荒漠区土壤种子库的研究进展,从土壤种子库的基本特征、时空分布、与地上植被的关系、研究方法以及影响因素等方面进行综述并提出研究展望。The desert ecosystem is the most fragile ecosystem in the world.In recent years,research on conservation and restoration of desert ecosystems has attracted widespread attention.As the seed source,soil seed banks play a vital role in the restoration of vegetation.This paper reviews research on the soil seed banks of desert regions worldwide in the past 20 years and covers the basic features of soil seed banks,their spatial-temporal patterns,the relationship with above-ground vegetation,research methods and the factors influencing soil seed banks.Some suggestions have been made for future work.
