Review of soil seed bank studies--soil seed bank function in natural ecosystem

Soil seed banks have an important significance in vegetation systems.Memory is an important function of soil seed banks since it can reflect the history and process of vegetation succession,and be used as a means to trace vegetation development.A main use of soil seed banks is in vegetation restoration,so soil seed banks have been widely used by restoration workers.Normal vegetation regeneration depends on the potential vegetation supply of soil seed banks and that determines the trend of vegetation succession or development.In a degraded vegetation system,the theory and technology of soil seed bank donors should be emphasized in studies as a significant base from which to practice and rebuild soil seed bank function(SSBF) for vegetation restoration.
