摘要
土壤种子作为植被自然更新的物质基础,它是所有存在于土壤中以及上层凋落物的具有活力的种子,连接了植物种群群落的过去、现在和将来.土壤种子库时期是植物种群生活史上的一个潜种群阶段,在植被种群更新、演替和恢复的过程中扮演着重要的角色.该文主要从以下几个方面论述了土壤种子库的研究进展,包括土壤种子库的形成、研究方法、分类、空间格局、时间动态、与地表植被的关系、影响因素以及在恢复中的作用.并针对在土壤种子库研究中出现的问题提出了建议,特别提出在干旱河谷区这样的生态极其脆弱的区域,加强本底的调查和研究,有助于该地区植被恢复和重建工作.以期为今后土壤种子库的研究工作提供参考.
The soil seed,being regarded as the material basis of the natural reproduction of plants,is the ac-tive one in the soil and the withering,connecting the past,the present,and the future of the plant population. The period of the soil seed bank is a invisible one for the plant population,and plays an important role in the course of reproduction,succession and resumption. This paper is to discuss the soil seed band from the following aspects,formation,research methods,classification,spatial patterns,temporal dynamic,relation with the land vegetation,influential factors,and the effect on resumption,and put forward some solutions to the problems,es-pecially those of the dry valleys. This will be helpful for the resumption and reconstruction of plants,hoping it will be a reference for the future study of this subject.
