高寒草地土壤种子库研究进展及展望

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。土壤种子库理论作为群落生态学和恢复生态学的基础理论，是退化生态系统重建的重要组成部分，已成为植物生态学研究的热点问题。研究土壤种子库是对生物多样性研究的一个重要补充，有助于对植被更新和植被演替动态的了解，对于植被重建与恢复具有重要意义，更有利于指导生产实践。草地土壤种子库作为潜在的植物群落, 是种群的定居、生存、繁衍和扩散的基础, 是草地未来地上植被发生的源泉。从草地尤其是高寒草地土壤种子库的研究方法、研究内容、意义及存在的问题等方面进行系统的总结并展望了未来的研究趋势，以期为将来高寒草地土壤种子库的研究提供一些理论基础，并为高寒草地的植被重建和恢复提供理论指导。

The advance and prospect of soil seed bank in the alpine grassland

Soil seed bank indicates the total amount of survived seeds in the litter of upper strata and in the soil.The theory of soil seed bank is regarded as the basic theory of community ecology and restoration ecology,an important component for natural regeneration in degraded ecosystems,and has become a hot issue in plant ecology.The study of soil seed bank is an important supplement to biodiversity research,helps to understand vegetation regeneration and the dynamic process of vegetation evolution,and is indisp...
