中文摘要	To assess the potential contribution of soil seed banks to seedling recruitment, and to the vegetative processes of dune systems in semi-arid areas, a comparison of temporal variation in soil seed bank was made between active and stabilized dune systems in northeastern Inner Mongolia, China. The results showed that between-year difference in seed density for the stabilized system was smaller than that for the active one, but there were similar variations with season in seed bank for both dune systems. Furthermore, seed densities of the dominant species on the respective dune type (i.e., annuals on the stabilized dune and psammophytes on the active dune) varied more sharply with season, but more gently in annual variation than those of other phytogroups. These findings suggest that (1) seeds of annuals in the soil of the stabilized dune, or seeds of psammophytes in the soil of the active dune contributed much to seedling recruitment or plant species colonization, (2) the relationship between soil seed bank and seedling recruitment was complex in both dune systems.
