土壤种子库研究的热点问题及发展趋向

扫码查看
土壤种子库是指存在于土壤上层凋落物和土壤中全部存活种子的总和.土壤种子库是种群定居、生存、繁衍和扩散的基础,也是植被潜在更新能力的重要组成部分,在植被的更新、演替和恢复过程中起着重要的作用.本文总结提出了土壤种子库研究的几个热点问题以及发展趋向,包括土壤种子库的研究方法,入侵植物的土壤种子库,种子雨、种子库与地上植被的关系,种子库在退化生态系统植被恢复和生物多样性保护中的作用,土壤侵蚀对土壤种子库的影响,全球变化对土壤种子库的影响.同时对这些领域的研究进展进行了综述,旨在为进一步推动今后土壤种子库的研究工作提供参考.
Hot Topics and Developing Trends in Soil Seed Bank
Soil seed bank constitutes all diverse seeds presented on or in soil and the associated litters. It is not only a basis of plant population establishment, survival, reproduction or dispersal, but also plays an important role in vegetation regeneration, succession and restoration. This paper summarized some hot topics and trends in the studies of soil seed bank, which included: 1) research methods of soil seed bank, 2) soil seed bank characteristics of invasive plants, 3) relationships among seed rain, soil seed bank and the related standing vegetation, 4) roles of soil seed bank in vegetation restoration of degraded ecosystems and biodiversity conservation, 4) effects of soil erosion on soil seed bank, S) influences of global change on soil seed bank. Meanwhile, some related research progress was reviewed with an attempt to provide references for future research of this area.
