土壤种子库研究现状

根据文献从定义、研究方法、现状、主要结论、研究趋向几个方面对土壤种子库进行了总结。提出对于土壤种子库的研究应着眼于干扰生态学的基本理论,以退化生态系统的重建和群落交错区的演替为主要内容,以定位观测为宜;以群落为整体,从植物结实到种子库的萌发及萌发幼苗的生长这一完整过程来讨论植物群落的种子库,这将更准确地反映植被更新演替的实际情况;还应对在不同环境条件如何影响种子萌发,土壤种子库在野外自然状态下的萌发状况和时间波动规律等方面作进一步的探讨。

Study Progress of Soil Seed Bank

The author summarized the study progress of soil seed bank from the concept,the study methods,the main results and the further research.Those studies of seed bank are not systematic and from the shorttime investigations rather than the long-time.And it is few about the succession of the plant community that is at the edge from one type community of plant to anther type.So at the base of the theory of the disturbed ecology we should strengthen the studies of the plant community succession at the collected plots for a long time at the edge of the two different types;we should study the whole process from the seed germination to the new seed input to the soil to completely mater the law of the succession;and we should study the effect of different condition on the seed germination and the changes of the seed bank in different time.
