Abstract: Soil seed bank includes all live seeds existed both in litter and in soil,which is simply classified into transient soil seed bank with seeds germinated within a year of initial dispersal,and persistent soil seed bank with seeds remained in soil more than one year.Even giving ideal germination conditions such as season,temperature and moisture,some seeds in soil,including persistent soil seed bank,still remain dormant.Investigation of soil seed bank has always been paid attention by plant ecology,and has been an active research area.Persistent soil seed bank confers the potential for regeneration in circumstances where unpredictable disturbance happened to the established vegetation temporally and/or spatially,and accordingly,plays a key role in vegetation restoration and management after disturbance.Researches on persistent soil seed bank can make the content of biodiversity abundant,and provide more ways to understand vegetation regeneration deeply.This paper reviewed the methodologies of persistent soil seed bank study,the classification and indication factors of persistent soil seed bank,and the significance of its study.The problems and further work of the study were pointed out.
