Abstract  

Soil seed bank includes all living seeds existing both in litter and in soil.Investigation of the seed and spore bank has become a recognized and indispensable part of plant ecology now and has been an active research area.The soil seed bank is one of the life history stages of plant populations,which is called subpopulation stage and acts as the base of settling,living,reproducing and spreading of plant populations.The theory of soil seed bank is regarded as the basic theory of community ecology and restoration ecology,an important mechanism for natural regeneration in degraded forest ecosystems,and has become a hot issue in plant ecology.With its development,the methods of soil seed bank research are more scientific and precise;meanwhile the content is updated and supplemented constantly and the fields of research include botany,genetics,ecology,weed science,agronomy and other sciences.Up to now,a comparatively full and complete framework of theory in soil seed bank has been achieved,which can be summarized as following: 1.development and direction of soil seed bank;2.characteristics of the soil seed bank;3.dynamics of soil seed banks;4.classification of soil seed bank;5.methods used in the seed bank research;6.its contribution to plant ecology.
