Abstract: Biological soil crusts, which are widely distributed in deserts, can affect morphological features and physical-chemical properties of topsoil and thus affect the seed dispersal, seed germination, seedling survival and growth of annual plants. This paper reviews the studies of the interactions between biological soil crusts and annual plants, summarizing internal mechanisms of the effects of biological soil crusts on soil seed bank, seed germination, seedling survival and growth process. The paper also points out that biological soil crusts have a selection on annual plants growing on them and gives some prospects to the further research.

Key words: biological soil crusts, annual plants, soil seed bank, germination, seedling survival
