摘要
近年来,受损湿地生态系统的植被恢复与重建掀起了湿地植被恢复的热潮.种子库是过去植物的"记忆库",是湿地植被自然恢复的重要潜力.本文从湿地种子库的形成、湿地种子库的规模及空间分布格局、湿地种子库的物种组成及种子库与地表植被的关系等几个方面总结了湿地种子库主要研究内容的国内外研究进展,并重点介绍了湿地种子库在湿地植被恢复中的应用研究,尤其是湿地种子库幼苗萌发主要影响因素、湿地种子库种苗建群适宜生境及湿地种子库植被恢复潜力等内容的研究现状.在此基础上,对目前湿地种子库及植被恢复研究存在的问题以及将来可能的研究方向进行分析,以期对湿地种子库植被恢复理论及实践技术的发展提供参考.
Recently, restoration and reclamation of vegetation in degraded wetland ecosystem have become a hot subject. As a res- ervoir of past plants, seed bank has huge potential for natural re-generation of wetland vegetation. In this review, we provided an overview of the major researches and progresses in the wetland seed bank formation, size mad spatial pattern, species composition and relationships between seed bank and standing vegetation at home and abroad. Some case studies of wetland restoration using soil seed bank are introduced here, especially focused on main factors ＇,affecting seedling emergence of soil seed bank, safe sites for establishment of seedling and restoration potential of soil seed bank. We further discussed the main problems presented in the wet- land re-vegetation from soil seed bank at present research and its possible direction of future studies. This review is expected to be a key reference for the development in the theory and practical techniques of restoration of wetland vegetations from soil seed bank.
