摘要: 土壤种子库物种构成及数量特征一直是植被科学研究的热点问题,同时土壤种子库数量特征具有空间、时间分布属性,这些问题的研究对揭示土壤种子库的植被生态学机制具有重要意义。影响土壤种子库形成的各种因素干扰着种子库存在状态和输入、输出特征,因此研究土壤种子库外在影响因素具有重要意义,土壤种子库的研究方法对土壤种子库数量结果影响很大,因此综合前人研究,发展适宜研究对象的取样、分析方法能够得到可靠的结果。以后的研究还应集中于所研究植被的土壤种子库容量探查上,明确种子库物种构成,这对植被演替、发展及植被管理有重要指导意义。

Abstract: In our study to understand soil seed bank mechanisms we investigated several topics such as species diversity, seed number and their spatio-temporal pattern. All these are important for understanding soil seed bank mechanisms in vegetation ecology. A knowledge of soil seed banks can help with the planning to optimize inputs for vegetation regeneration source and nutrition. All of these factors influenced soil seed bank form, disturbed soil seed bank state, and inputs/outputs. In the study of factors influencing soil seed banks, research methods are an important factor that can affect the result, so we should refer to former experiments to develop good, objective methods to obtain reliable results. In the future, studies of soil seed banks should focus on soil seed bank capacity and composition, as these are important guides to vegetation succession, development and management.
