摘　　要：种子萌发是湿地植物生活史的重要阶段,种子能否成功萌发对湿地植被的结构组成具有重要意义。作为湿地生态系统结构的决定性因素,水文情势影响湿地植物的种子萌发和种苗更新过程。重点综述了不同水深、淹水持续时间和水位波动对湿地植物种子萌发的影响,分析了淹水影响种子萌发的作用机制。未来应加强野外条件下湿地植物种子萌发特征研究,比较不同生境下同类物种的萌发规律,探究不同湿地植物种子萌发的特异性及内在机理,为湿地植被恢复实践提供科学依据。Seed germination is an important stage in the life cycle of wetland plants,and the success of seed germination is crucial for the composition and structure of wetland vegetation.As a determinant factor of wetland ecosystem structure,hydrological regimes influence the seed germination and seedling recruitment processes of wetland plants.This paper focuses on the impacts of different water depths,duration of flooding,and water level fluctuations on seed germination of wetland plants and analyzes the mechanisms through which flooding affects seed germination.Future researches should focus on enhancing the studies of seed germination characteristics of wetland plants under field conditions,comparing germination patterns of similar species in different habitats,and investigating the specificity and underlying mechanisms of seed germination of different wetland plants.This paper will provide a scientific basis for the practices of wetland vegetation restoration.
