| 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.The soil seed bank,as the potential for regeneration,plays an important role in the natural restoration of vegetation.This paper reviewed its research methods,including sampling methods,sampling time and identification of seedling.It suggests that long-term anchor observation is adopted for the dynamics of soil seed bank and seedling specimen bank should be founded to identify seedling correctly. |
